5 out of 5 eggsmaybe the best board for the $

Pros: Very low latency between SSD and Graphics card makes gas flow model runs very quick (relatively). running Flownex to model temperatures of a pure H2/O2 combustion in a gas turbine to project potential overheating issues in the metal walls and blades of the engine. 20 minute time takes 22 hours to model in double precision computation. Times using nonM2 boards have been in the 23 1/2 to 25 hour range using a 295X2 and AMD 8320. Memory is OCZ3P1600 LVAM4K and OCS3P1333LVAM4K @1333 set for 16 k page files. Intel does not fully support 16K page files so their times are in the high 25 hour range even with memory set a 2166. .

Cons: Do have to watch heat. Fans for 295X2 are mounted externally to the case.

Other Thoughts: I am trying to do some computations on a budget that others do using Cray or IBM machines at places like LBNL or ORNL. This makes it possible to consider the option.

5 out of 5 eggsAwesome Board

Pros: Awesome board smooth install and very easy to overclock. It comes with 3 preconfigured overclock settings with the highest being a 30% overclock, of course you can still do your own overclock as well. The board boots fast and performs well . With a 35% overclock the board still runs cool with now problems under stress test with prim95, Furmark, as well as 3dmark and crystal for benchmarking, . The looks of the board are great as well as long as you are doing a red and black theme.

Cons: No cons yet hopfully this board has good longevity in it.

3 out of 5 eggsGood but with issues

Pros: - Looks good
- Works well and has solved the base issues I was having with my previous board
- Audio is separated from the motherboard

Cons: - Lots of complaints over the Killer NIC made me get different drivers for it before I ran into issues
- Lots of issues with memory compatibility, from what I have experienced and read online
- Not thrilled with the UEFI Bios, or how it ties my CPU overclock directly to the RAM, which neither myself or a friend of mine had ever seen

Other Thoughts: Bottom line is that the board works and is stable, so I decided to keep it instead of spending the money to return it ($15 shipping + $20 restocking fee + the $25 I paid for shipping to get it) and get the motherboard I should have gotten in the first place.

My only real complaint comes down to the memory compatibility. I run an AMD FX-8320 and had been using 16gb of Patriot Viper Xtreme Series Div 2 DDR3-1600 Ram. When I attempted to overclock my CPU with the new board to 4.0Ghz, I noticed it dropped my Ram speed from 1600 to 1333, no matter what profile I selected, XMP or otherwise.

The UEFI gave me Drop down list options for Ram speeds, either 1333 or over 1600, which my memory could not handle because it doesn't OC at all. I tried manually setting the speeds, but despite multiple attempts and internet searches, I either couldn't figure out how to do it correctly or the Bios just wouldn't allow it.

More searching online led me to other people also having issues with memory, and I found on the ASRock website the fine print saying that this board does not cooperate well with DDR3-1600 Ram with any CPU overclock.

I found a review that had someone saying an ASRock tech told him to use ONLY Corsair Vengeance or G.Skill Ripjaw memory for use with the board. Since I didn't want to be out $60 from shipping and restocking fees and then have to wait for another more expensive board to come in, I decided to upgrade my RAM to some G.Skill Ripjaws X DDR3-2133.

I plugged the RAM in and without an overclock it was detected fine, (although I think the timings are off), but as soon as I bumped my CPU up to 4.0Ghz it dropped my Ram to 1333 again. I was able to manually select 1840 from the drop-down list, but if I tried to select the next closest value to the actual speed, which was about 2150, my computer would not POST.

I tried a few things to remedy this, but for now just have my Ram set at 1840. I know Ram speed isn't that big of a deal, but it doesn't thrill me that I am having all of these issues with this board that I've never had with any other board. If I could have done it all again I'd have gone with one of my other more expensive options for motherboard choice.

That's what being in a hurry to buy a replacement board for a broken one gets me. Live and learn.

Manufacturer Response:

Dear Valued ASRock Customer

We sincerely apologize for any inconvenience this may have caused you.
The mainboard has overclocking function. However, overclocking could damage the components as well as mainboard which depend on user’s knowledge, experience and adopted components.
Please try only multiplier setting, if its adjusting other setting in the BIOS.

If you have any technical Support inquiry, please contact us at http://www.ASRock.com/Support/tsd.asp. We will assist you shortly.

Thank you

4 out of 5 eggsSWEET BOARD FOR THE PRICE POINT

Pros: I got this and a 8350 to bridge the gap till I go intell in August .
I would have gone with an asus board , except they no longer believe in customer service and like a huge amount of others , I've been through heck with trying to deal with them . So since I've had a few great asrock boards and this one had everything I wanted . So far it's been a great oc board .

Cons: Came with no sli bridges .

4 out of 5 eggsGood Board

Pros: Good looks, built-in killer nic, and excellent performance with my 8350.

Cons: If you get random blue screens under light loads then you must reinstall windows. I went from ASRock 970 extreme3 to this board and because of the different chipset I had to reinstall windows 8.1. Some of the drivers were the same however a clean install is the only way I could get it to stop blue screening.

5 out of 5 eggsBang for the buck

Pros: Where to begin ! Built my rig just over a year ago on a budget for gaming. Added a few things here and there when on sale, but mostly the same. First build for me since the Windows 98SE/XP days. Have maybe $700 inside this case.

My stats:
Asrock 990fx Fatal1ty Killer, FX 6300, Arctic Alpine 64 Rev2-AMD, 16 GB Gskill Sniper 1600 (9-9-9-24), 120 GB M.2 Crucial M500 SSD (OS), 256 GB Crucial MX100 SSD(Steam), 250 GB Samsung EVO250(Origin), 1TB WD (data/backup drive), LG DVD-RW, XFX R9-270x, Thermaltake TR2-600 PCU, Rosewill Challenger U3 case. Windows 8.1 64Bit.

Play all types of titles including Shadow of Mordor, BF4, DA:Inquisition, Thief, ES IV Oblivion, ES V Skyrim, Fallout: NV, ESO. This machine performs with NO overclocking needed @Ultra settings, never falling below 60 FPS.

That said, it is easily overclocked. Xboost and AMDs CCC functions give you adequate control and extra oomph if needed. My 6300 went to 4.6 stable with the stock cooler. Simple user interface.

UEFI is also very user friendly. UEFI enabled Bios update over 'net. No work arounds needed for machine to install Windows or recognize the drives. XMP profile works great for G Skill.

No bloatware required. You don't have to install any of the bloat if you don't want it. The Killer E2200 Ethernet port will accept the 8161 driver. On board sound functionality is better with the Realtek software, but not needed. That said, the Apps for this MoBo are decent. See Cons for 1 bugaboo.

Disk transfer rates when installing/backing up games, installing mods, etc. is sufficiently fast. Drive to drive with large files, I average 150-180 MB/sec. Slows down a tad with large amounts of smaller texture files, but never falls below 80MB/sec.

Board layout with this Rosewill case provides for easy installation, upgrade, and cooling. Case fan, USB, and other connections arrayed around the board for ease of cable management for even the most OCD nip and tucker (including myself). Only 4 wire ties were required. Visually appealing. See cons for 1 minor note.

Performance does not change relative to up time or extended use. I get the same FPS on a fresh boot that I will get 6 hours later. Temps are stable. See cons for minor note. OS remains stable.

In short: I purchased this while on sale and it doesn't owe me any money. If I do another FX build, I will be using this board.

Cons: I noted 3 minor cons in my pros, and it's really nitpicking to call them cons. Not even worth subtracting a fraction of an egg.

Con 1: Apps and software updates. AT LAST CHECK. To get the latest updates for some of the bloatware, you have to go to the 88X Killer page on AsRock's site to get them. Network manager being one of them. It's almost as if they stopped uploading the updates to the 990fx page.

The board's memory support list could be updated as well. Although that's probably an issue for all MBs.

Con 2: The SATA connections are on the bottom right corner. Consider having two cables with 90 degree connections and 2 with straight. Was not a real problem with my case and the back wire channel lining up with the ports, but for smaller cases could be an issue.

The M.2 shares with the ESata, so you can't use ESata rear or front with an M.2 SSD on board. I really wish there were 1 or 2 more SATA ports to work with. If I had one beef with this Mobo, this would be it. Would be nice to throw in another HDD or optical drive.

Con 3: As many will find on various forums, the Northbridge runs hot. I'm not sure if it's really a con and designed to run that way. Mine averages 60-63 Celsius. It climbs there within 3 minutes of boot BUT stays there even after extended use.

Not really an issue for me, because to overclock this machine would be only for benchmarks and bragging rights. I don't need it. Those who will be overclocking may want to consider alternate cooling for the north bridge.

Other Thoughts: Would buy again. Would recommend to a friend.

5 out of 5 eggsGreat Upgrade

Pros: 990FX Chipset - Easy setup.

Cons: none

Other Thoughts: I upgraded to this from an ASRock 970 Extreme3. Best part was the base drivers are the same, except for the NIC. Since I use straight up AMD Drivers I easily swapped my boards around, and started up with no issue.

My FX 6300 still tops out at 3.8GHz in Turbo, but I have found this to be the norm with the 6300 revision I am using.

I got this somewhere else as part of a deal when I build a friend a new computer.

5 out of 5 eggsSmooth

Pros: UEFI bios, S/PDIF Out, 3 Year Warranty, easy overclock utility, Purity sound, eSATA, 7.1 CH HD Audio with Content Protection, fast boot, dehumidifier, XFast RAM etc.

Cons: The only con for my configuration, was the positioning of the SATA slots In the chassis. It was very tight on two of the SATA connections.

Other Thoughts: if you are not used to the UEFI bios, walk slowly if you're going to overclock in the bios. It is much more complex than previous bios versions. F-stream an easy to use overclock tool. If you enjoy complexity, you will have fun in the bios. My computer was built using a Samsung 840 EVO SSD drive, a 1 TB HDD drive, and 32 GB of crucial ballistic DDR 3-1866 memory. The memory overclock easily to 2133. This computer is smooth, sleek and fast.

1 out of 5 eggsBAH

Pros: Red and black.

Cons: Requires HDD's to have a special type of partition. Very little support from customer service.

Other Thoughts: I forget if it requires a GPT, or an MBR partition. Whichever is less common. My EaseUS partition master software was unable to configure my SSD (Radeon 240GB SSD) to be compatible. Radeon's support didn't even understand what was going on.... Swapped out with an ASUS Sabertooth, no issues, running.

Manufacturer Response:

Dear Valued ASRock Customer

Thank you for purchase and review.
The HDD partition (GPT or MBR) is not related to mainboard but the drives and OS.
However, mainboard works with both GPT and MBR.

If you have any technical Support inquiry, please contact us at http://www.ASRock.com/Support/tsd.asp. We will assist you shortly.

Thank you
