ASRock 990FX Extreme4 ATX AMD Motherboard


Pros: Price to performance ratio (cost was $144 at time of purchase), Overclockability, Quality components

Cons: Strange voltage, Cheaper aesthetic appearance as compared to the Extreme3

I got this board more than a year ago (Christmas 2012) and paired it up with an FX-6100, thus far they have been a great combination.

This board has been great in many ways: The UEFI BIOS has many features that look cool and function greatly. You can use your mouse in the BIOS (but I still prefer the keyboard). There are many options for overclocking, for example I was able to overclock my PCI-E frequency from 100Mhz to 110Mhz which in turn increased my graphics performance. Speaking of graphics cards, this motherboard allowed me to SLI two 560ti 448's which was a major selling point.

Overclocking the cpu was a bit of a chore because I lost at the silicone lottery with my FX-6100, I know this because I put a friend's FX-6300 in and it overclocked much higher at lower voltages. I had my 6100 running at 4.5Ghz at an idle voltage of 1.488v and a load voltage of 1.504v, the strange thing is I had the voltage set at 1.4625v in the BIOS. Also another strange thing was if I LLC set on at all it wouldn't boot or would crash under load. Anyways, I had to down my overclock to 4Ghz because Far Cry 3 would make it bluescreen. For some reason Far Cry 3 was the only thing that would make it bluescreen at 4.5Ghz, well it doesn't anymore at least.

So all-in-all this motherboard has had its issues, but the main thing is it has lasted for more than a year with the abuse I give it, the same can't be said for other components. Now that I think back on it, this motherboard and I have been through a lot, I got to 5Ghz on this board, I once pushed the voltage to past 1.6v (that was a bad decision by the way), despite this abuse the board keeps on chugging forward.


Pros: Good overclocking mobo especially for beginners and novices. Still enough for the experienced I believe. Very functional bios if you RATS.

Cons: Nb Heat sink may affect having water cooling kit if you have mid tower case.

Hey you guys and ladies .I haven't had this board too long. How ever just from having it the amount of time that I have and for the fact that I am new to Asrock. I was able to catch on to overclocking in bios because of RATS. The auto overclock feature actually does work in the bios. However don't forget to do your research and disable certain functions like cool n quiet.

CLR CMOS button on the back actually works. This is a plus for noobs and people who do suicide runs. Means you can leave your side panel on whilst overclocking. Now if you do something to really just jam up the bios then just pull the side cover off and move the jumper for a few seconds. Put it back and then get back to what you were doing. Now the jumper is a pain in the ASK! The NB heat sink will get in the way so this could have been positioned somewhere else as well as the battery.

My set up is running a phenom ii 1055t with a gtx 650 2gb. No problem Fps are great and wouldn't mind picking up another one to sli or maybe even tri sli. I always hear amd and Nvidia don't get along. I am happy with the setup. There is also no bottle neck.

I have had no real problems from ram. Running just some plain old pny 2x4g kit. It is set at 1333mhz and while overclocking ram actually reached 1666 before I had to back it down to the next ratio and kept right on pushing. Reached about 3960mhz with out no trouble on stock cooler out of case with ambient of 66f. I don't see a lot of guides for clocking with this board and has I learn more about it I will probably make one.

The NB didn't give problems when I tried to keep it around 3000mhz. The heat sink cooled it enough and ran nb voltage at 1.3 but with the optional fan that was scary to put on it stayed cool and rebooted after stressing with no problems.

The power and reset switch on the board is a nice touch. Allows for benching or testing with out having to have a case around.

So if you are new to overclocking or on a budget and need a decent overclocking mobo I would say go this way. 139.00 on amazon good performance/dollar ratio. I have to say this, even though you are new to overclocking read before manually overclocking. You can very well damage stuff if you are not careful read all the screen. Get some basic understanding. If you are just too scared to mess with bios use the auto overclock in the bios for some 30-40% gains. Mine posted 50% for 1055t didn't try it because I didn't have the cooling.

I have no regrets of buying the 990 extreme 4 motherboard.
