Great board. Easy install & good manual. Nice debugging LEDS. Not everclocked yet. Runs very well with Ubuntu altho dont recommend Redhat flavours (at all)

Great board

Bought this board for my first build. Combined it with a 5750, 2x2gb ram and a phenom ii x6 1050t.

As soon as I booted up the system and had it all set up, it gave me the option to overclock my system, taking the processor from 2.8 up to 3.6 with no effort on my part. It also overclocked my RAM. Being my first build I couldn't compare it, but it seems to tick all the boxes for me.

The first one sent to me was faulty though.

A Masterpiece

This is the best AMD motherboard ever built. The board features tonnes of gadgets to overclock your CPU, Memory and it even has voltage check points for accurate voltage readings. If you are after a high end motherboard then this is it.

Humzah 2011-04-20


Awesome motherboard easy to install, and performs perfectly. And the service with OCOUK was great. cheap cross europe shipping and I had the package in 2 working days which was 2 days faster than expected . Will definitely order all future computing needs from here. Thank you !

Best AMD motherboard

This is by far the best AMD motherboard. I've got an AMD Phenom II X6 1090T CPU and 8GB of Corsair Dominator DDR3-1600MHz RAM on it. I've overclocked the CPU to 4.1GHz with a mere 1.43V and the CPU-Northbridge link to 3.0GHz with as little as 1.28V. This is using Load-Line Calibration at 100% on both. The temperatures I get with these voltages are amazing and stability on my system is absolute.

Add to the overclocking capability USB 3.0 and SATA 6Gbps support and I'm as happy as could be with this motherboard. These are the three reasons I upgraded the motherboard even though my system was alright with the Asus M4A79XTD EVO motherboard I previously had.

A little more expensive that what I used to ever want to pay for a motherboard but the quality shows in every respect and is worth the money. If you're shopping for an AM3 motherboard, do not doubt - get this one!

Kayron Mercieca 2011-01-20

very good

very good . thats all i can say if your no good overclocking just use the turbo evo(software with board ) and it goes to 4 ghz straight away without trying .
if you want to get your hands dirty then there are so many options to power it up and you really feel its rock solid . i used a thermaltake frio cooler and to use all the memory slots you either have to install your memory first or as i did take the front fan off the cooler put your ram in and replace, its very tight in fact i use xms3 ram but if you use ram with big cooling fins on it you wont get it in with this cooler be warned !! . anyway ive never got over 40c with my setup and ive really pushed it my 1090t at 4.3ghz for hours of work, no kidding !!. mind you i have my own method for thermal compound and i always get low temps with coolers . this boards ace, get it get a 1090t and push it . i know i can get more and im just waiting for a rainy day to push it all to the limits awsome board . sorry about the essay !

if u want a computer with power and with a future proof motherboard i would recommend this at the top of the list, not only it has USB 3.0 he looks good fits up to 4 ati graphic cards and with its other features which i cant explain cause theres so many :) 10 / 10 recommended card and i was going for a i7 but AMD just changed my mind with there new core and with motherboards as quality as this

Dez 2010-10-28


I bought this board along with 4Gb of Corsair Dominator RAM, the AMD 1090T CPU and a ATi 5870... which replaced my ageing set up (Asus Commando, Core 2 and 4850 etc).

Absolutely outstanding motherboard in my opinion, looks cool too and should last me a good few years (just like my old Commando board).

Recommended 10/10

Best MotherBoard money can buy

I Bought this a few weeks ago and wanted to give it time to be used before I reviewed it. 100% love this board, its beautiful and works like nothing else I have ever used with some great ideas to make overclocking easy and safe. If you are tempted to buy it DO IT!

Ray Kirkland 2010-09-10

Great Board!!

I bought to replace my AM2+/AM3 board (NF 980SLI) as Ive come back to AMD again and got this nice and cool board, very cool with features,etc.. also working prefect with DDR3-1600mhz (recommend with 6-core CPU) that run so faster that would blow your hair out - highly recommend plus thanks to OCUK for excellent service with higher speed 10 out of 10!!

Martin 2010-07-21

Absolutely Awesome

Asus Crosshairs IV with Phenom II x6 1055T, 4GB 1600 corsair 7,8,7,20 and Sapphire HD 5850 cooled by Zalman CNPSXtreme in Coolermaster Scout case using Raid 0 2x Hitachi 1TB drives.

Board is by far the best ever made for AMD systems, Be aware, no legacy IDE or Floppy one of reasons I bought it, Layout 5*, performance 5*, OC 500* best board for OC on AMD system at moment, have run 1055t to 4.6ghz on air on this board, use good memory though, corsair XMS3 1600mhz 7,8,7,20 runs perfectly at over 1900mhz, 9,9,9,24 on this board

Heatsinks large but low so dont impede large CPU coolers (CNPS10X Extreme) but Memory slots close to bracket so be wary of large memory heatsinks, my XMS3 fit in correct slots under cooler edge, but larger sinks would have meant using black slots only.

Raid works perfectly, Bios perfect for tweaking, Playing out of box is awesome, voltage points are great for death runs, Buttons work well, Unlock cores great, (tested 550 to x4)

Just buy it!!!

Mike 2010-06-30

Just buy

I don't have any issues with the bios version, this product is one of the best product for amd, easy step to get 4.5Ghz and 1800Mhz at 9-9-9-26. Get it now!!!

Ploutarchos 2010-06-10


Did an 8% overclock automatically on install for my 955, so it fsater than a 965 at standard.
So many features that I'll never use them all.
My next step is to crossfire my 5770.
Couldn't get it to post first time so tried another case and bingo.
Great delivery and technical support from OCUK - as is to be expected from them.

Asus Crosshair IV Formumla AMD 890FX

Well brought this board to accomodate a new parts I was using to build a new PC. First off, the board looks very good asthetically. 2. 6 SATA 6Gb/s ports are helpful although I couldnt get a Samsung Spinpoint F3 1TB SATA-II HDD to be recognised in any of them and had to plug it in the single SATA 3Gb/s. Nice range of well layed out PCI slots. However if your running a graphics card that takes up two back slots on the case and you want to run a wireless network pci card and a tv tuner card you have to put the Graphics card at the bottom and cant fit any more in crossfire. Chipset stays around 28 degress (celcius) at idle and after playing silent hunter 5 for 4 hours and pc being on for over 4 days it still didnt rise above 35. degreess.

Pure brilliance

My first proper mobo and I'm not dissapointed at all. It's awesome to just look at, let alone use. Didn't need to do anything to get it up and running, just plugged and played, and matched with the new hexacore it's amazing.

If your thinking of buying it, just do it.

Richard 2010-05-22

Lovely Board, and a great looker too

This board does it's job admirably, and comes with a suite of tools that should get any novice tinkering away at an overclock of some sort!

My only gripe is that after POST, Windows will not boot at default settings requiring an automatic OC to boot properly.

Currently running my AMD X6 1090T @ 3.8GHZ stable simply by the push of a button.

To top it all it looks the nuts in a Corsair 800D case, with red Dominator GT ram installed :)

Now if only overclockers would get some Enermax Magma 120's in to match the colour scheme ;)

Swampy 2010-05-13

Great board

Fantastic board and performs great and look the biz too, specially when it's inside a lian li armorsuit case and matched with g.skill ripjaw ram in red.

My only issue is that it wanted to automatically overclock my 550be from 3.10ghz to 3.60ghz which caused my pc to crash during windows install and had to reload default settings. Also when i unlock cores it decides to overclock again, which caused me problems. However great board
