Summary: I needed a cheap/cost effective backup server for my operation. My only requirement is it must be able to handle more than 32 GB of ram. This is the cheapest board I can find and I am sorry that I had it. Ended up with a different SuperMicro board. It was more expensive but worked right out of the box.
Pros: low cost
Cons: It was only able to detect 1 dimm for cpu0's dimm slots. I didn't feel like returning the board so thought I would move both the cpu and all 3 dimms to cpu1. The board would not even post.
Summary: Should have bought an Intel board. This one has caused way too much headache. There are many other dual socket 1366 boards out there.
Pros: Cheap, dual socket, lots of PCIE, PCI slots
Cons: First board was stable 2 months, then would randomly crash ESXI. RMA'd to Supermicro and they confirmed it was bad, but out of their initial replacement warranty. They finally overnighted one on our UPS account after two weeks of "Testing".
Pros: price is good, ATX, supermicro's tech support
Cons: too many problems, in win 2003 cpu errors in event viewer if you have 2 CPU's in there. if you enable RAID it wont boot from some CD's , such as memtest. if you update the bios to the beta version it fix all the problems but locks up at NVRAM check because the chip set is too hot. solution is to put a Fan on the chipset and block all the pci-E slots. well I don't call that a solution though
Summary: I bought this board to run ESXi. ESXi installed just fine on this board, but without reliable dual CPU support, I am returning this board and going with an Extended-ATX SuperMicro board. Spending a little more money, but I think it'll be worth it and hopefully it'll work this time.
Pros: Cost, dual Nehalem CPU support, ATX form factor, Supermicro tech support (every time I called, I was on the phone with a real life person within a minute, not only that, they dont spend 20 minutes with ret@rded, useless questions like your name, number, email, address; they get right to the point. I like that)
Cons: 1st one was defective. When both CPU's where installed, it wouldn't post. SuperMicro support said it's bad and to RMA it. Got the second and and it worked for a couple days, then socket #1 went dead. SM said to update the bios which I did and it didin't help. RMA'd
Pros: Rock solid performance, stable, slots are conveniently placed for dual Corsair H50 cooling systems and superb customer support. Every time I called for help somebody is on line in less than a minute!!!
