Summary: I have 3770 OC to 4.3 with no problems. It's basically left on 24/7, and down volts to around 1.6G unless I'm gaming. Upgraded the BIOS off the bat to Ver (?). I have had no problems at all what so ever.
Summary: I purchased two of these along with Intel Core I5 processors and couldn't be happier - works great on an ATI Crossfire gaming setup with six monitors on one computer and three on the other. ASRock hit it out of the ballpark with this one! Highly Recommend!
Summary: I purchased this MB a year and a half ago and no problems with it what so ever. Great purchase being with the MB they through in a set a 2 x 4 GBs of G-Skill Sniper Ram. Went perfect with the 3570k Intel chip. Glad I decided on the AsRock Extreme 4. Grab it!
Summary: Using this motherboard for a HTPC/plex server build. It has been running great over a year now. I bought it because of the price and features i was looking for in a HTPC build. The 2 feature i must have is the xRAM and THX certification. Added 16 GB ram and i disabled the pagefile and set the all temp and IE cache folders to the RAM disk. Saves my little SSD.
Summary: It's ok. There are no onboard sounds, because the onboard speakres do not work. Also, if you'd like to set up RAID, the 6G SATA will be retarded to 3G SATA for the purpose of your RAID. What? I can have 3 separate, 6G throughput drives, but not one RAID array w/6G throughput? Why would you build a board like that? Outside of that, I really like it.
Summary: Some parts like the onboard usb and the sata are slightly difficult to access from time to time, but once you get them in the function of the board is great. Onboard sound and video are decent (if you're slowly adding parts to a new clone build).
