3 out of 5 eggsApparently has been opened before

Pros: Fast shipping to FPO/APO

Have yet to test board. Please see cons below.

Cons: Box had a tear in the tab. Opening the ASROCK box cover to display the inner board showed the bottom box (this board ships with the board in a cardboard tray and the accessories in a separate box underneath). Upon removing the motherboard the ASROCK decals show scratches as well as the 12v connector for the board itself showed signs of use.

Other Thoughts: I haven't tested this board yet as I am at work on my lunch break, however I am disappointed to see that this item was tampered with previously. I will update this post to see if this board will post. If the board posts I'm not going to bother with a RMA process, however it is annoying to spend 170.00 on a product that is suppose to be new that isn't new.

4 out of 5 eggsASROCK 990FX Extreme9

Pros: Board looks good, (knocked off 1 egg, See other thoughts), was able to overclock my 8350 out the box at stock volts to 4.6 ghz
Easy overclocking ability.

Cons: Software and Drivers.

Other Thoughts: FIrst of all, when I received this board from NEWEGG, the packaging was perfect, no dents in the box at all, I opened up the box and inside was the motherboard box, again perfect condition. Opened up the box, everything inside was sealed and new. Board was tie wrapped into the protective cover, again perfect.
I took the board out and what catches my eye? SCRATCHES! I looked like it was slid across something. I was thinking that they put a protective coating on the heatsinks and all i had to do is remove them, but there is no plastic covering.
After spending $170 dollars on this board, i would expect to get a NEW board.
Anyhoo, I contacted New egg and after 3 days of going back and forth, they agreed to RMA it for me and send me another one, FYI THIS BOARD IS NON-REFUNDABLE!! They are paying for shipping and stuff so that is good.
Im sure it is not NEWEGGS fault, the board probably came from the factory that way.
Fingers crossed that the next one is in better shape.
plus I have to go without a computer for another 2 weeks. GRRRR!
Now as for the software, Im gonna keep this short. The USB ports (All of them) stay on ALL the time. So after a few reboots, it stopped recognizing my external HD, I worked on it for 2 days with no resolve. I ended up having to use the USB 2.0 slot for it to work correctly.
Again, maybe it was just a bad board and the next will be better.

All in all this IS a good board, everything else works smooth. Im not saying dont buy it, i will repost after I get the replacement board.

3 out of 5 eggsJust so you know

Pros: I do like the layout of the board. The way the heat pipes are laid out actually allows me to get a little bit larger cooling fan for my CPU and memory.

The look of the board is fantastic. I didn't think that I'd like the "doo-doo brown" color, but it actually is subdued enought that you can't really tell what color it is while in your case.

Cons: This board is picky about what memory you use in it. I mean like pickier than a woman, during "that time of the month", and has been spoiled all of her life by her daddy kind of picky.

I've been using a Gigabyte 990FX-UD7 board and had no issue with the 32GB of ram. ASRock...not so much. I tried memory from other computers ranging from Kingston, Corsair, GSkill, and Mushkin. It didn't like any of them. I'm now goated into buying more memory (and I did check the memory compatibility listing before-hand)

Oh! It would be nice if this board came with some Crossfire connectors instead of SLI. Motherboards should have both in their packaging. I know that sounds like much, but it really isn't. There was a single SLI connector and a 3x SLI. Why not get rid of the 3x SLI and add a Crossfire connector.

Other Thoughts: I'm going to keep the board and turn it into a gaming rig. I'm presently over in Afghanistan and it's kind of hard to keep this thing from being/getting dusty. I'm going to seal it up and send it home to my brother so that I'll have it when I get home.

5 out of 5 eggsAnother excellent Asrock high end mobo

Pros: Asrock has really upped their mobo design, engineering and quality in the past two years, IME. They now offer some of if not the best mobos available and for considerably less than the over-hyped Asus mobos - many of which I've also used and tested for reference.

The E9 is a slightly updated version of the 990FX Fatality Professional mobo without all of the Johnny Fatality marketing nonsense. The E9 functions just fine out of the box but it shines when it comes to overclocking because of Asrock's superior 12+2 phase CPU power supply design. The E9 is one of only a handful of AM3+ mobos that can properly power the FX-9590 and FX-9370 CPUs without overheating the VRM and throttle the CPU.

Despite the claims of some reviewers the E9 works just fine with RAM at 2133 MHz. and higher. Obviously if you don't understand that RAM is rated at it's maximum stable frequency and not at what speed it will run overclocked with a specific CPU, then you haven't done your homework and aren't properly setting the BIOS settings for the RAM to run at the default 1866 MHz. or higher frequency. This is a USER Malfunction, not a hardware issue. You folks need to educate yourselves and stop blaming the mobo and RAM makers for your lack of technical knowledge.

Cons: I haven't found any cons yet other than reviewers who lack the technical skills to properly adjust the BIOS settings. Building a properly functioning PC takes more skill than just assembling the components in a PC case. Obviously a number of folks here are in over their heads technically and they should perhaps buy a pre-built PC since they don't seem to have the required skills for building a modern PC.

Other Thoughts: Asrock has some of the best customer support in the Biz, IME. I have used all of the brand name mobos from Asus, Intel, Gigabyte, MSI and many more. IME customer support from all of these mobo makers is terrible. I was pleasantly surprised to find that Asrocks U.S. and Asian customer support is far, far better than the rest. I had heard this prior to trying the Asrock brand but I had my doubts. While there is always room for improvement my experience with Asrock tech support has been lightyears ahead of the other mobo makers.

While I have not had any need to test Asrock's warranty service it has to be better than Asus'. Two of Asus' mobos failed while under warranty and when I returned the one that was 3 months old they sent me what looked like a discarded mobo that had been laying in the trash bin. It was covered in filth and had some caps replaced by hand. It was a complete garbage replacement for a like new, 3 month old mobo that I returned. The trash warranty mobo was returned to Asus and I bought a Gigabyte mobo to replace it. No more Asus mobos for me as they use several companies to manufacture their mobos and as a result you never know what the quality or performance will be. With Asus' warranty service being totally unacceptable, I won't go down that road again.

4 out of 5 eggsasrock 990fx extreme9

Pros: This is an update for my previous review.. While my bios is still un-usable for overclocking anything,, and my 2133mhz gskill is still at 1600mhz,, I was able to get my FX-9370 4.4ghz overclocked stable to 5.0ghz using the asrock extreme tuner utility! Also my thermaltake water 2.0 performer keeps it below 65c degrees during 3D mark 11 which I got a score of 10185 with single EVGA GTX-680 4gb card!! Also the first mobo Ive noticed a difference a difference in speed between USB 2.0 and USB-3.0,, nice! ,, and the Intel lan is also way better!!


Other Thoughts: Here is my system info:
Asrock 990fx extreme 9
AMD FX-9370 4.4ghz @5.0ghz
EVGA GTX-680 4gb
32gb Gskill ripjaws- z 2133 @1600? not on compatibility list?
Kingwin 80+ gold 1000w PSU
Thermaltake water 2.0 performer closed loop cpu cooler
Rosewill thor v2 full tower case..
I am really liking this board now!

5 out of 5 eggsAll of the best, without the price!

Pros: 990FX, lots of PCIe lanes
Additional USB3 and SATA controllers
Intel NIC on-board
Clean UEFI, nothing hidden like in Asus or Gigabyte designs
EXTREME overclockability with 12+2 power phase design on digitally controlled MOSFETs
220W power output for FX-9xxx
4x PCIe 16X size (limited to 8X,8X,8X,8X)
Only one PCI slot (thank you ASRock for finally moving forward)
And a whole lot more

Cons: The placement of the 4 PCIe 16X slots make it impossible to install 4 2-slot video cards into as two are right in sequence.

Other Thoughts: I spent a lot of time researching for a motherboard that could handle the FX-9590 properly and produce a highly stable system for video production, and ASRock caught my eye as the fore-runner with the power phase design on the Extreme9. I do not intend to overclock, but this is really what they were aiming towards, with a system that can increase power dynamically while holding to a very tight tolerance for fluttering.

Some reviewers here and elsewhere have given this motherboard and ASRock a bad reputation, but for the record 99% of the reported problems are driver generated. If you opt to use this motherboard, I recommend you use the most recent drivers from the ASRock website, and the chipset driver directly from AMD.

Please remember that the power requirements for the FX-9xxx series is much greater than the older FX CPUs, and don't short yourself in choosing a power supply unit.

For the record, my build:

ASRock 990FX Extreme9
AMD FX-9590 (bare model)
Corsair Hydro Series H105
G.Skill Sniper Series DDR3 2133Mhz
Corsair GS Series 240Gb SSD
2X WD Black 2Tb
Corsair RM-1000 PSU
Windows 8.1 Professional

3 out of 5 eggsasrock 990fx extreme9

Pros: board looks great,, can use my fx-9370 now ,, uifi bios

Cons: more false advertising about being 2133mhz compatible,, nothing new in the AMD world though..I tried a bunch of different settings even xmp profile, nothing,, wont boot.. will only boot win7 64 ultimate at 1600mhz ! unless you have a degree in memory timings,, which I do not,,your stuck at 1600.. I have 32gb 2133mhz gskill ripjawz z installedI was hoping the memory controller in the piledriver processor was better but I guess not! Also using xfast auto oc at boot failed too.. would not load windows

Other Thoughts: Well so far its not much better than my MSI 990fxa gd80v2 And fx-8150 At least it would run my ddr3 at 2133mhz, And I was able to get the most "unstable" overclocking board to 4.4 ghz stable! Wish msi would get off there butts and make fx-9370 compatible mobo

Manufacturer Response:

Dear Spode911,

We sincerely apologize that you having difficulty with memory speed setting.
Due to CPU memory controller on FX series is 1866, beyond that speed may considered as overclocking.
Please set the speed manfully 1866 or 2100 to check if its solved.
For the reference, visit memory support list link at " ".

1 out of 5 eggsasock 990fx extreme 9

Pros: looks great, dehumidifier, lots of features.

Cons: DOA.... you can hear i running POST the cd rom spinning, hdd spinning. no video report. So I tested the PSU, ram, vid cards, everything worked. I put it all together on the mobo box same results, so I sent it to RMA department. I hope to get my replacement soon then I will re post.

Other Thoughts: I have used other asrock mobos in customer builds with no problem, so I am disapointed that the first I get one for myself I have problems.

Manufacturer Response:

4 out of 5 eggsASRock 990FX Extreme9 AM3+ Motherboard

Pros: ASRock makes great motherboards

Cons: My dual video card covers up the PCI Express 2.0 x 1 slot that I need for my raid card. also its a SATA3 insted of SATA6. this was my fault for overlooking this. I thought it being Extreme9, that it was a new model.

Other Thoughts: I have a ASRock Fatality board in my other computer and would have got another, but Newegg was out of stock. Wish I could have waitted.
