Summary: I used RAID 5 with WD black drives for 3 years, switched to this motherboard (which is amazing in every other way) when I wanted to upgrade my RAM capacity, and have only had heart ache with the RAID controller. Everyone everywhere says I need to use WD Red drives instead. Thats fair...mostly...kinda...except I had been using WD black for years, now suddenly I have to purchase a bunch of new Red drives instead, really?
Summary: I purchased this item to build a home VM server. I used 2 5667 cpus and 48GB ram along with 2 Noctua NH-U9DX 1366 heat sinks. I spent more on the heat sinks since I'm using this in a home office and I wanted the setup to run quietly. Its working fantastically, here are a few things you should know: This is the version with IPMI support. You probably really do want this feature, so you can reboot and access the console remotely.
Summary: I think I know Mountaineer's problem. He probably has some of the screw hole things in his case in area that the mobo does not have screw holes. I had this problem when I first got my board and it would not detect all my memory (sometimes only half or less) and the machine would turn on and be impossible to turn off. The problem he describes seems very similar to what I had when one of the screw holes was shorting the memory slots and possibly more.
Pros: Alll that I listed before
Cons: All that I listed before except now the PCI-E speed with my areca raid controller is mostly fixed with a new BIOS from SM
Summary: I bought this board instead of the supermicro board that has 18 DIMM slots due to the fact that this one is regular EATX and not E-EATX like super micro's 18 DIMM boards. So far the board has worked great and IPMI is a nice extra but not really needed in my situation. This board cost $30 more than the board that has 18 DIMM slots and had x16 PCI-E slots but they wouldn't fit my case.
