ASRock P67 EXTREME4 (B3) LGA 1155 Intel P67 USB 3.0 ATX Intel Motherboard

Pros: So many of the good things I have to say about this board have already been said in other reviews, so I'll simply reiterate that it is fast, stable, and packed with great features that are seldom found at this price point. The "Clear CMOS" button on the rear panel and POST code display on the motherboard makes the "trial and error" process of overclocking so much less painful!

System runs great configured with:
i2500k @ 4.0 GHz (WEI 7.6)
G.Skill Ripjaws X DDR3 2133 (9-11-9-28 1T) (WEI 7.9)
Crucial RealSSD C300 128GB (WEI 7.9)
Gigabyte GeForce FTX 550 Ti (WEI 7.4)

Cons: The SATA II/III connectors are mounted parallel to the motherboard, which makes them rather hard to get at in many cases. On the flipside, though, this is beneficial to aesthetic cable management

Overall Review: To spare you some hair loss, here are the fixes to some issues you may encounter:

1. Have DDR3-1866 or DDR3-2133? It is undocumented, but only slots 2 & 4 support these XMP profiles. Using slots 1 & 3 will result in failed stability tests like Prime95 or Intel Burn Test unless you've left the RAM running at the slower DDR3-1600 (the default in UEFI).

2. Stuck on POST with code 98 (especially when overclocking)? Move your mouse and/or keyboard to USB3 ports

3. Device manager missing the driver for "Simple PCI Communication Controller"? Download the Intel Management Engine from the Asrock site.

4. Hard drives not scoring as high in WEI as you expect? Download the Intel Rapid Storage Driver & BIOS from the Asrock site.

5. It goes without saying: don't use the CD that comes with the motherboard. Download the latest drivers and BIOS from the Asrock site and save them on a USB drive, then install them all (starting with the INF files) to ensure maximum performance.

Pros: Nice features. LED display on board for error codes is very nice. Handy having power, reset, and c-mos reset buttons on board.

Cons: My board has an error and will not boot up anytime there are 2 sticks of memory present (and the one stick can only be in one particular slot). When I started researching this error code #45, it seems it is a common problem with the board. RMA here I come!

Overall Review: I read a lot of glowing reports on the board before I bought it and found nothing about this memory problem until I had it. Google error code #45 for this board, you'll find no shortage of people discussing it.

I do like the features of the board, so I'm going to try another one, against my better judgement.
