To get ourselves prepared for the transition towards the next Intel mainstream, namely the P67, I

would like to share my personal findings by writing up this overclocking guide to get people to be

more familiarized with this platform. Any further comments and suggestions, please do kindly POST

after this thread.

First of all, lets look at the CPU Core speed. The existing Intel Sandy bridge CPU has been classified

into three categories, being the full unlocked (i.e. the K series), the partial unlocked (the non-K 4

core), and locked (dual core) processors. Up to date, there are only 2 models around, being the

2500K and 2600K. The major difference between the two is with the difference in CPU Ratio and the

support of HT, where the 2500K is a 4C4T processor without HT, while the 2600K is a 4C8T processor

with HT support, both with the absolute highest CPU Turbo Ratio selectable of 57x as I was told.

To my own experience, there is not really too much work involved to maximize the overclock

capability of these two 2 processors. Lets start with the key power options:


3/19

CPU Tweaking under Sandybridge platform:

To maximize the CPU performance on the K series processors, you can try to follow the following

flow chart:


4/19

Note:

- It is recommended to keepC1EandEISToption enabled for the best overclock capability.

- ALL CPUs provides native support of up to DDRIII-2133 when been used on a P67 platform

regardless whether it is a K or not. DRAM Ratio on P67 regardless whether or not it is a K series

processor.

- Considering the raise and fall of BCLK results in the relative change of the DRAM frequency, please

try to clock down the DRAM to the next highest option available if the current DRAM frequency

results in a bottleneck for BCLK overclocking.

- You can also try to trade a few BCLK for the higher DRAM frequency if your DRAM can take it.

- Keep in mind that a higher BCLK is 90% dependent on the CPU, and 10% on the motherboard,

meaning that though a better Motherboard can yield you 1~2 MHz difference in BCLK stability, with a

CPU does 2MHz of BCLK higher would possibly give you more margin for overclocking at the end.

For the partial unlocked processors, just raise the CPU Turbo ratio to the highest CPU Turbo Ratio

option available, follow by the ensuring:

EIST= Enabled

C1E= Enabled

C3 Reporting= Enabled

C6 Reporting= Enabled


5/19

Doing so will give you the absolute best CPU Ratio. Then follow the same flow chat as the K series,

while only doing the BCLK overclocking while with CPU vCore below 1.3V should be able to give you

closed to best performance reachable by your processor.

Now lets get onto some serious business:

OC with K series walkthrough:

Considering we now have the background knowledge necessary for Sandybridge OC, we can now

begin our OC journey. Lets start off with 1.450v CPU VCore, set CPU Turbo Ratio to 44x, then check if

it boosts into OS.

After we had an success with booting into OS, we now raise the CPU Turbo Ratio to 45x, then check if

we can still boot into OS.

If yes, set CPU Turbo Ratio to 46x, then check OS boot capability again.




Somewhere along the way you will encounter trouble booting into the OS. You can try to increasethe Vcore slowly, till around 1.55V (Note: decent CPU is required to raise the CPU Vcore this high).


6/19

You may eventually find your CPU to top at around the CPU Turbo Ratio of between 48x and 49x, i.e.

fails to boot into OS with 49x but 48x does. Now we have gathered the info needed, and lets move

on to the second step, maximizing the overall performance now!

We have talked about previously that BCLK maximizing also maximizes the RAM frequency, and all

Sandybridge CPUs support up to DDRIII-2133 DRAM Ratio when been used with P67 chipset

regardless if it is a K or not. (A 21.33 x BCLK Ram speed in other words) Other ratios including the

1866 (18.66xBCLK), 1600 (16xBCLK), 1333 (13.33x BCLK) and lower are also available for your pick

when needed.

Therefore if you have a set of RAM that can only do 2000MHz and not more, you will have to adjust

your BCLK / DRAM Ratio to try to hit as close to this sweet spot as possible. In this case, either 107.2

BCLK with 1866 DRAM Ratio OR 93.7 BCLK with 2133 DRAM Ratio are both ideal choices. For some

who may feel disgusted with under-clocking their PCIE (though real world performance difference

can be questionable) let us just focus on 107.2 for this example if the CPU boots with this BCLK,

considering the BCLK limit DEPENDS 90% on CPU and 10% on the motherboard.

Back on with our walkthrough, now keep the Vcore that you have set previously (Probably 1.40v to

1.50v region), and try to lower the CPU Turbo Ratio to 36x and try to raise the BCLK to a bootable

state that is not to surpass the ability of your RAM. You can try going by 0.2MHz steps to speedthings up (Yes, you are right, most P67 based motherboards allow BCLK adjustments of 0.1MHz in


7/19

each step).

Once you have found your Max BCLK, you can now go back and find your MAX CPU Speed by going

with 48X and increasing BCLK till it crashes. In this case you should expect to reach something like

4850MHz! This is then the best performance you can squeeze out of your CPU that you should try to

target. Finally, set your configuration to the configuration best suit the top performance you have

found a minute ago, i.e. 45 X 107.2MHz with 1866 DRAM Ratio (i.e. 4824MHz@DDRIII-2000)

and you are most likely to be able to hit the max all round performance, going by the example above.

If you own a non K processor, then skip the part about the CPU Core ratio and just set the Turbo

Ratio to the highest possible option, then find the maximum BCLK, with the minimum Vcore needed

of around 1.30V. This should be more than enough for around 4GHz of speed.

So you see it is such a straight forward platform Much less complicated than P55, X58.


8/19

Some commonly asked Questions:

Q: Why does the board need to shutdown at every change of BCLK?

A: Since almost all boards use the Southbridge PCH to generate the base clocks for the CPU.

However, as the Intel Management Engine requires such process to make even the tiniest BCLK

adjustment of 0.1MHz if that change is done in BIOS.

Note:

(1) Making such changes under OS does not suffer from the same limitation.

(2) The higher BCLK you boot with, the more likely you can hit the maximum speed under OS. (ie

105.0MHz boot + adjust to 108.0MHz in OS is easier than 100.0MHz Boot + adjust to 108.0MHz in OS)

Q: How does it do Under Liquid Nitrogen?

A: As the Core frequency scaling capability is inversely proportional with respect to the change of

temperature when the CPU temperature goes down too low, the overclock capability of the CPU

actually reduces dramatically when it reaches below zero degrees. For example, a CPU may do

5.0GHz @ 0C, but only 4.9GHz @ -40C. The ideal temperature for overclocking the Sandybridge

processor under the P67 platform is around 15~20 degrees.

Q: What kind of BCLK should we expect to hit?

A: A processor with the capability to raise the BCLK up to 106~108MHz should be considered a good

Sandybridge processor in terms of BCLK overclocking.

Q: Is there any specific batch that we should look out for?

A: No Data yet, BUT CPU variance is big so keep watching!

Q: How is its DRAM overclocking capability as compared with P55, X58?

At least on par with P55. However, it is still limited by the 2133 ratio + BCLK Limit restriction. A good

4x 4GB combination with high DRAM frequency may be expected.

I was lucky enough to have received one of the upcoming P67 board for Christmas, which I have used

to write up this overclocking guide. Suppose this is also a good opportunity to showcase it here as

well. Please do feel free to read on if you are also interested in this board.

First is the boxing. Nothing fancy from the first glance, just like its older brothers. All features and

specifications are marked in the inner cover and the back of the package. You will be able to see the

board itself before making the actual purchase. (That is only if I am the one paying for this board of

course)


9/19

Now let me take the board out to eventually be able to take a closer look at it

The colors used on this board is very similar to what has been used among all other Asus ROG board,

using black and red as its main theme, and a bit of white for a high contrast final touch. The heatsink

has been designed with a futuristic look, and of course, with that breathtaking ROG blinking LED logo

on it to tell everyone that you have just passed another ROG.

Enough of chat, now lets go onto business. As it is easier to read from top to bottom, I will start from

the power solution. The Maximus IV Extreme continue to adopt the award winning Extreme Engine

Digi+ VRM design, which was first found on the Rampage III Extreme, featuring the digitalized power

solution with alloy choke, FET+, dual driver, and the ML Cap.


10/19

Unlike traditional digital VRM designs, where each power phases are connected in series, which

requires a high switching frequency, the Extreme Engine Digi+ found on the Maximus IV Extreme

overcame this limitation by changing the VRM structure from serial connection to parallel, allowing

the power to be outputted from each individual power phase instead of having to go through all

phases to prevent the need of high switching frequency. With the use of high quality parts such as

FET+ and alloy choke to enhance the heat dissipation by up to 1.3 times

Together with 40% higher conductivity and 25% higher current capability, and the use of dual driver

which packaged the PEM controller with two power driver in one, delivering the ultimate power

solution that is ideal for Extreme overclockers. Furthermore, with the delivery of up to 5 levels of

Load-Line Calibration, with the industrys most precise control of switching frequency of 10KHz

increment and voltage control of as low as 0.005V per an increment plus the ability to make real-time

adjustments, opening users with the full control of the onboard power solution like never before.

Below is the combination I have found which allow me to stably push my CPU frequency up by

another few BCLK higher, may be worth trying if you own this very same board:

Finally, it is also worth mentioning about its capability to support the software-free implementation

of the Asus EPU via BIOS control. Users are now finally able to utilize this power saving feature

without any software or additional power calibration process which was once needed on the Asus

boards.


11/19

One thing I found interesting is that the Asus ROG team seem to have putted more thoughts into the

design of the PCI Express lane / slot arrangements to try to maximize the overall performance of the

system. Unlike the traditional design of inputting the entire x16 lane of PCIe from the CPU directly

into the NF200 PCI Express bridge chip, it actually divide the PCI Express lanes with a set of 4 quick

switches to two sets of x8 first

to try to minimize the additional latency introduces by the NF200 in the best way they can. According

to their design, you will be able to enjoy completely latency free PCIe connection when one or two

cards are connected, and at least one card without such latency when running 3 way SLI orCrossFireX configuration. Below is the table outlining the best PCIe slot utilizing scenario for this

board to achieve the absolute performance for your next benchmark:


12/19

Out of all available features, the one feature that catches my eyes completely is the USB BIOS

Flashback feature, which allows me to flash BIOS with only an USB flash, the board, and PSU (With

the AC power cord connected of course.). Yes, no CPU, no DRAM, nothing else is required for either

BIOS upgrade, downgrade, or even BIOS recovery.

All I need is the press of the ROG Connect button. Now this is sweet and useful, as I try to fiddle

around with my BIOS a lot, I somehow found a feature that make my hobby bulletproof if I continue

to use this board.

Also onboard are the following neat features which Asus have added to make the overclocking

journey more enjoyable for its users. Though I have yet to be able to have a chance to play with all of

them on this board, I still find them interesting, and will definitely try to spare some time to play with

all of them if I can. After all, they are already there

and it wont hurt to play with them to find my own use of them I suppose. Here after is a direct copyfrom the document that Asus provided me with along with the delivery of this board. Do feel free to

read on if you are interested in them.

RC Bluetooth

System Debug and keyboard-free overclocking have evolved a long way in the past years. However,

regardless of any existing design, users still cannot gain the full control the system without either

opening up the chassis, or simply getting back to the good old trusty keyboard. Thank to the new

Asus TweakIt technology via the iROG processor, users can now gain the full control of the keyboard-

free overclocking and debug tools wirelessly via their very own Bluetooth device anytime, anywhere.

ROG iDirect

The remote control, overclock, as well as hardware monitor capability of RC Bluetooth has made its

way to the MAC platform. With the new ROG iDirect, users can now gain the full control of the

keyboard-free overclocking and debug tools through the USB, Bluetooth or WiFi connections via their

very own handhold devices from MAC such as the iPhone, as well as the iPAD, transforming your

handy everyday gadgets into a power OC Remote.

The new and polished ROG Connect

As recognized by overclockers worldwide, the Asus TweakIt Technology always come with full of

surprises. This new implementation is no exception. Unlike the early design with the need to open up

the chassis while dodging through series of cables to reach the onboard buttons, while having the

limited display and control capability without the need to install additional software on the working

system

users can now kiss goodbye to the limitations of the past, and enjoy the joy of overclocking with the

new and improved TweakIt technology, namely the ROG Connect. Though it is known that ROG

Connect is the one and only solution that allows users to use any separate system as the control

terminal of the ROG system to be overclocked, and conduct the last mile overclocking, or watch POST

status of the system since the launch of this technology, the development did not end there.


13/19

With the newly improved ROG Connect, users are now be able to conduct real-time remote monitor

of system health status together with the control capability of the key functions remotely, and of

course, the ability to update BIOS remotely even when the system needed such update is not

powered up. Finally, and not the least, theGPU Tweakit, allowing its users to tweak the GPU

Frequency, GPU Vcore and GPU RAM Frequency remotely, overclocking the VGA card on the fly

without generating

LN2 Mode

Cold-boot bug is a barrier which overclockers often need to face when conducting subzero

overclocking with LN2 (Liquid Nitrogen). When cold-boot bug occurred, CPU will no longer POST till it

has been warmed up again. The LN2 Mode exclusively supported by Maximus IV Extreme enables

users to remedy this limitation, delivering non-stop smooth extreme overclocking capability, which

makes Maximus IV Extreme the perfect choice for all overclockers under LGA1155 platform.

Q ResetExtreme overclockers may sometimes face the hard decision between whether they should reset or

force power down the system when the extreme overclocked rig half once in a while, as the press of

reset button does not always work, while force power down may often result in freezing the

components under S5 mode. This is where Q Reset comes in. With the exclusively design Q Reset

button at the top left hand corner of the board, users will be able to clear CMOS then power up in a

flash to bypasses S5 mode to avoid the need to face either of these limitations.

EZPlug - More Power for the Power Hungry Monsters

The Maximus IV Extreme comes with two additional set of 4-pin Moles plug, delivering extra power

to both the USB 3.0 ports as well as the VGA cards. This enables not only better compatibility with

USB 3.0 devices, it is also ideal for the power hungry monster VGA card when conducting extreme

overclocking.

PCIe x16 Lane Switch

The five PCIe x16 Lane Switches found at the right hand side of the DIMM slots can be used to disable

the PCIe expansion cards installed onto each individual PCIex16 slots. This is ideal for benchmark

tests when comparing the difference in performance under different configurations, as it allows

quick changes without the need to remove each individual card.

BIOS Flashback

The Asus exclusive Inter-switchable Dual BIOS design allows user to keep two different BIOS versions

for different purposes. Users can keep one version for extreme OC, while the other for stable use.

BIOS configurations set on the two BIOS chips can also be kept separately, and inter-switchable with

simple one touch BIOS switch, making Maximus IV Extreme an ideal choice for all extreme

overclockers.

EFI BIOS featuring EZ Mode

Asus has been long known for its rich available BIOS option, the Maximus IV Extreme is not an

exception. However, considering the adjustments of the BIOS options has always been a difficult taskfor the entry level users when building their very own system for the very first time, Asus has hence


14/19

implemented the most user friendly BIOS interface named EZ Mode. Featuring a simple, clean

yet intuitive user interface listing only the most vital options for everyday usage, the BIOS

adjustments become something that is available to all users. Furthermore, the nature of being an EFI

BIOS also ensures its future-proof for the new technologies to come.

ROG BIOS Print

The dump of the BIOS setup screen often involves highly trained photographic technique, while the

outcome may not always be as satisfactory as it can be. Users can create the BIOS screen dump with

a simple press of theF12 key, and the BIOS screen shot will be stored to your USB storage

device automatically. ROG BIOS Print, your best friend when sharing BIOS screen with your friends.

GPU.DIMM Post

Troubleshooting is a long and tedious job, especially when you dont know what actually fails. Asus

GPU.DIMM Post scans through the PCI Express slots for available graphic cards, as well as the

presence of DIMM modules installed during POST stage, and displays the result in the BIOS setup

screen.

This helps the users to find out if anything has gone wrong with the installation as well as the

detection of the device without the need to try and error on their own, allowing users to

troubleshoot for the cause of errors with ease.


15/19

CPU Socket Monitor

As the numbers of CPU socket pin increases with each new generation of new processors, the CPU

became less tolerant to improper installation. In worse cases, the CPU socket may even burn out in

the result of short circuiting due to improper installation. CPU Socket Monitor enables the

motherboard to detect the temperature of the CPU socket, preventing the CPU socket been burnt

due to short circuiting.

AI Suite II

AI Suite II is a user friendly interface combining all popular Asus applications in one single package forflexible use. With the full customization capability covering the add / remove of application module,

the change of colour and skin and how the software should auto hide itself when not been used. AI

Suite II integrates a large variety of applications covering features from all different, including:

- For System Tweaking:

- TurboV EVO: To enable the instant access to the performance related BIOS options aimed to

provide a little more edge when conducting extreme overclocking

- DIGI+ VRM: Allows making direct alternation to the behaviour of the onboard digital VRM in real-

time.


16/19

- EPU: Allows the access to the intelligent power saving engine onboard, help to save every last

penny on your power bill.

- Fan Xpert: Allows the full customization of how the CPU and chassis should work in the like of the

users with just a few clicks on the mouse.

- For Real-time Monitoring:

- Probe II: Allows the real-time monitoring of the key voltages, temperatures, and fan speeds

together with warning capability to warn the users when any of the readings exceeds the threshold

set by the user.

- Sensor Recorder: Allows the users to show the key voltages, temperatures, and fan speeds in a

graph for a quick tracking of the system status. Furthermore, an historical record can also be kept for

later reference if needed.

- Side bar: There is the display of the sensor and CPU status at the right hand side of AI Suite II to

allow instant monitor of the system status when fiddling around with other applications.

- System information: To quickly show the CPU and DRAM info without the need to install any

additional third-party applications.

CPU Level UP

Users can enjoy the quick and easy system boost of system performance by selecting the processor

users wish to have, and the TPU will handle the rest. With a variety of CPU profiles to choose from,

users are able to experience the performance boost just like having a CPU upgrade.

Go Button

This is yet another exclusive revolutionary feature from Asus, which allows your motherboard to

boot even if there might be some compatibility issues between the motherboard and the memory.

All the user has to do, is to simple hold the Go Button till the red LED begins to blink to ask

motherboard to take the charge of self-memory patching process, and fix the memory compatibility

before your very own eyes

till the system finally able to boot up. Once the system completes the system POST, this button will

then become the quick and easy OC button, which overclocks your system to your desired settings

once been pressed.

iROG

iROG is a series of highly specialized microprocessor on the motherboard that makes overclocking

easier and more rewarding. Together with AiSuite application inside AiSuiteII, allowing users to make

adjustments to the key overclocking related options on the fly

or applied in the next boot sequence whichever way desired. With this specialized microprocessoronboard, users are even able to conduct external control of the BIOS options remotely via desired


17/19

devices using ROG_Connect and RC_Bluetooth, making the last mile overclocking more rewarding.

ProbeIt

Asus ProbeIt allows users to use their own testing equipments to measure the major power sources

on the motherboard, allowing display of the most accurate voltage readings externally without the

need to spend time on the guesswork to locate each measuring points.

COP EX

Being able to overclock is good, however, due to the risk of damaging components, it is always a

good idea to buy some insurance along with that. The COP EX allows overclockers to increase chipset

voltages without the need to worry about overheating. It can also be used to monitor and save a

potentially overheating GPU.

Voltiminder LED

In the pursuit of extreme performance, overvoltage adjustment may sometime be necessary, thoughextensive risks may be brought up along with it. Acting as the "red zone" of a tachometer, the

Voltiminder LED displays the voltage status for CPU, PCH, and Memory in an intuitive colour-coded

fashion for quick voltage monitoring.

Loadline Calibration

To protect the CPU from the possibilities of been damaged due to over loading above its maximum

TDP, the CPU manufacturers specifies a guideline and regulation defining how the voltage behave

with respect to raise of the current consumption of the CPU. However, this behaviour also leads to

the potential instability in the case of overclocking

where the Overclockers has to raise the CPU Vcore higher than it should just to compensate the

result of this effect. This is where Load-Line Calibration comes into play, where the CPU Vcore will be

raised automatically to compensate its drop due to the change in current consumption, allowing the

CPU to be clocked higher with a lower CPU Vcore configuration.

OC Profile

Overclockers often need to keep a number of BIOS configurations for different purposes such as the

optimization for different benchmark applications. Furthermore, considering the CMOS clear is so

widely used by Overclockers, this cannot be ideal if the configuration gets cleared along with the

CMOS clear process.

This is where the idea of the OC Profile came from, not only allowing users to store up to eight sets of

secured configurations on the motherboards, the capability to save and load to the USB storage

device also making it flexible for any purposes, including experience sharing with other Overclockers.

Q-Shield

Asus Q-Shield is the first in the industry to deliver convenience and safety to DIY users. The

revolutionary design makes the tedious and tiring job a joy, at the same time when preventing the

chances for making cuts in the fingers of system builders when installing I/O Shield.


18/19

Q-Connector

Connecting front panel I/O is another tedious yet tiring job when building systems, especially when

the chassis happens to be either compact, or in abnormal shapes, as it is difficult to connect the small

pins into their respective headers in the set order. With Q-Connecter in hand, users can arrange all

cables prior going into the chassis, making system building one more step closer to joy rather than

pain.

Q-DIMM

This is yet another innovative feature Asus has added onto this motherboard. In order to avoid the

need to remove large graphic cards when changing DIMM modules, ASUS has hence developed the

Q-DIMM memory slots, with single sided latch, it does not only avoid the possible conflicts with large

graphic cards on the topmost PCIex16 slot, yet makes the memory removal process faster and easier.

Q-Slot

In order to reduce the difficulty of removing large VGA cards from PCI Express slots, while still beingable to secure the card in place when been installed, Asus has developed the Universal PCI express

slot with auto-lock and easy unlock capability. With the presence of Q-Slot, removing multiple large

graphic cards no longer cause headaches no matter how big the cards are.

Q-LED

Users often wonder around dont know what to do when system fails to boot up properly. Through

more experiences trouble shoots system failures with debug tools such as PC speaker and Debug

Card, the troubleshooting process is still long and tiring. This is why Q-LED was introduced, to give

users the direct indication to where the problem might be, in order to resolve the boot failures faced.

All users have to do, is to check which Q-LED stays on when boot failure occurs, and the cause of

boot failure may be spotted.

Debug LED

Though it is already convenient to read the POST status with both ROG_Connect and Q-LED, there

are still some advanced users who would like to find out the exact state of POST sequence off the

board directly. This is where the Debug LED played its role in the game.

Users can now make use of Q-LED and Debug LED along with the reference table of the POST code to

find out exactly where the POST error occurred, making trouble shooting easier to achieve.

Onboard Switches

Available onboard are three function switches to allow easy access to the most commonly used

functions without the need to short front panel pins. The available function buttons are:

Start: For instant access to power the system ON or OFF outside chassis.

Reset: For instant access to the system power resets outside chassis.

CLRTC: For instant access to CMOS Clear without the need to fiddle around with jumper pins to

complete the CMOS clear process.

Q-Reset: For the instant reset of the system CMOS without interfering without facing cold bug issuewhile conducting extreme OC using LN2.


19/19

Go Button: For the quick and easy heal to DRAM related boot failures or the read in of user defined

OC profile. TPU will tweak and tune the DRAM configurations in the event of a quick 2 second press

of the MEMOK! button during POST failure or from S5 shutdown state. Users will be able to load the

OC Profile via the quick press of this button once the BIOS has passed the complete POST process.

BIOS Switch

For an instant switch between different BIOS chip along with their BIOS settings.

LN2 Mode Switch:

For the boost of OC capability when conducting subzero OC using LN2.

PCIEX16 Switch: For a quick and easy control of PCIe lane. User can switch off any cards installed

onto the four PCIex16 slots simply by a flip of the switch.

EZFlash2

In the past, the BIOS update process requires a functional operating system, or at least a bootable

storage medium to conduct BIOS update process via command line. However, as bootable storage

medium may not be so simple to prepare at present date due to the unavailability of handy tools to

complete such tasks. This is where EZFlash2 comes to play. With the ability to read from virtually any

storage medium partitioned as either FAT16 or FAT32 directly from the BIOS configuration menu,

making BIOS update process much easier in terms of the work involved.

Q-Fan Plus

Q-Fan Plus, the third generation of Q-Fan implementation extends its capability of being able to

adjust fan speed automatically with respect to the temperature detect to achieve quiet and efficient

cooling. With Q-Fan Plus, not only the CPU and chassis fan will be dynamically managed base on the

raise and fall of the CPU temperature, special temperature sensor cables are also provided to allow

temperature detection of up to 3 additional locations or devices. This extends the fan speed

management capability, allowing a more flexible usage of fans.

Fan Xpert

Fan Xpert allows users to design their very own fan curve with ease. With a few simple drag and puts

of fan curve, users can now design their very own fan control curves for the CPU fan wheneverdesired. Furthermore, for non-windows users can also make the use of the newly improved Q-Fan

option in BIOS to design their very own CPU curve as desired.

Lastly (yes, this is really the end of this long review, I promise (at least for today that is) the other

specs of this board are as rich as can be with such a limited number of PCIe lanes they can utilize.

With 10 USB 3.0 ports (front and rear all together of course), from the NEC USB 3.0 controller and

the VIA bridge chip, and 4 SATA 6Gb/s ports each with full bandwidth (as oppose to having two ports

sharing the same 500MB/s bandwidth from one lane of PCIex1.) all with full RAID support, and dual

Premium Intel LAN chip onboard, I really cannot find a reason to criticize the design of this board.
