Pros: Very stable for 7 months running Win Server 2003 64-bit. Never a need to reboot or even pay much attention to it. Plenty of memory expansion, and I'm only using 1 CPU (Xeon E5620). Will buy another for VM's, using more RAM and dual CPU's now that I know this board is fast and solid.
Cons: Yep, it's a HUGE motherboard. Fits well in SM CSE-836TQ-R800B case.
Summary: 1) it's HUGE - i can confirm it will fit in the COOLER MASTER HAF 932 case with minor modifications (bend two tabs at the top meant for holding a water cooler down and drill two holes up there for mounting screws) but even then just barely.
Pros: Really? Pros? What's not to say - with 6 core HT xeons your server think's it's got 24 CPU's - you can load it down with 144 GB of memory with 8 gig sticks. It's got sound, graphics, dual network, an ILO board, craploads of pcix slots, ich10r controller...
Pros: This is an incredible board: fast, solid, stable and reliable. It has built-in IPMI which yields a wealth of information about hardware health remotely (LAN). I think it's hard to go wrong with this board for a server build.
Cons: none (save perhaps that I can't get CPU temps via IPMI using ipmitool but that may be fixed with a BIOS upgrade)
Summary: Also, the IOH get's a bit hot at peak load in the 800D with a modern full sized graphics card blocking the air flow around it. I ended up having to cut into the acrylic for a 20 cm fan when the built in 120 and 140mm fans couldn't get the air where it needed to go. This is more a case issue and not the board but worth mentioning.
Pros: 2 procs, lots of built in USB ports, mostly good layout and TONS of expansion room. It makes a brilliant overall workstation/remote render box.
Cons: This board is going to take work to fit into your normal case. I put it in the 800D and as expected had to drill a few holes for it. The part that caught me offguard was that the 24 pin slot is near the top while the PSU in the 800D is situated near the bottom. My CM Silent Pro Gold just couldn't reach using the back panel cable management. A bit of dremel work and my cable length problems were solved though...
Summary: I am currently using 6 x 4Gig Registered ECC memory from Patriot. [Quad Ranked] When installing the memory I followed the manual's instructions for placement. Upon first boot I received a missing memory beep code (5 short, 1 long).
Pros: Nice board, lots space for ram, solid construction and plenty of features. It really is somewhat of an everything and the kitchen sink kind of board.
Cons: The documentation was a little off. Some of the details of the board listed in the Motherboard manual were off and the manual from the website was no different than the one I received.
Pros: * Obscenely high RAM capacity - 18 DIMM sockets - You can add 72GB of RAM using inexpensive 4GB modules, or 144GB of RAM using 8GB modules.
Cons: * It's got a relatively unusual layout and will not fit any ATX case and only a very few E-ATX cases. The biggest problem is that while most motherboards have their "I/O block" (keyboard, LAN, USB, audio) on the back panel at the upper edge (assuming a tower case) of the board; on this board the I/O block is about an 1.75" from the upper edge of the board - most cases do not provide any additional space here. Additionally, the board maxes out the E-ATX size spec, so m...
Summary: The motherboard is HUGE. It is longer than EATX, and I learned the hard way. I got another case, Cooler Master Cosmos (the largest case for nonserver use) and it did not have enough holes for the screws. I had to drill and tap some holes before I felt comfortable with it holding my CPU without bending the mobo.
Pros: Everything is compatible with VMware ESX 4i. The NICs and ICH10R are all detected by esxi, and work very well. No drivers had to be separately installed.
Cons: The manual has some stuff wrong, such as the triple channel ram configuration. In version 1.0 of the manual, it says use 1A, 2A, 3A, but in version 1.0a, it says 1A, 1B, 1C. Version 1.0a is correct. The board does not post if 1A,2A, 3A is used.
