I've been having a lot of problems with this board..
19 May 2014
Summary: Well, I would really go for another board.. I've had this one for about 2 years. My PSU kept on needing replacements every 8 or so months, so I replaced my PSU 3 times before realizing it was my motherboard. (No shortages).
Summary: Guide/Install was easy and product met all of the descriptions; although, I made the mistake of purchasing a processor without Video, so that didn't work right away. I purchased a $30 PCi-e graphics card which was fine.
Summary: This MoBo does NOT support Ivy Bridge CPU's. (Intel i5 / i7) That is Intel's new generation of CPUs. If you call Asrock, they will ship you a new bios chip. However, it was advertised as supporting Ivy Bridge. This clearly isn't true. When Asrock sends the new chip, it will take about a week or so.
Summary: Supports VT-D on i5/i7 non-K SKUs, works OK for an ESX test server for sure. 32GB of RAM, passthru USB, passthru 8 port SAS controller, additional Adaptec controller for VM pool storage. Set n forget.
Summary: Pros: can easily over clock this bad boy with 2500k cpus cons: none. This motherboard delivers, i was able to overclock my 2500k to 4.8 gighz. this monster is also stable with no crash's at all during hard core gaming with my 2 GPU setup.
Summary: The motherboard with an i5 processor works great. Built a work computer with a 1 Tb drive & 8 Gigs of memory. Very responsive with email, browser, several drawings and spreadsheets, etc. open. I'm spoiled now. I'm so impressed that I'm now looking for an Asrock Z77.
Summary: It was a great motherboard, I sent it back thinking it was bad, when its the processor that was bad. I would recomend this to people looking for a nice motherboard with all the bells and whistles for cheap.

Summary: I was getting a code "55" and it was acting as if it wasn't recognizing my memory. (DDR3-1600). It turns out it was that I had an Ivy Bridge (3.3 Quad) Intel CPU Processor, and not a Sandy Bridge. After a small hint on new egg, I called their tech support number (from there website).
Summary: This is my first ASROCK motherboard, and it will be my last. Not that the hardware is that bad, it's decent enough as far as motherboards go, but I had a major issue from day one: the on-board BIOS had no Ivy Bridge support, so I received an error code 55 on the motherboard's LED display upon POST.
