Pros: The Asus KCMA-D8 makes a great workstation board for the right set of applications. My work is primarily software development with IDEs and databases. I need lots of fast memory, fast CPUs with a sufficient number of cores, and the ability to run multiple monitors with good 2D performance. Moreover, since I work a lot, I want the system to be quiet.
Cons: The first one of these I received would not power up. I'm not really bothered with Asus; when you sell complex components in the millions, defects are inevitable. Newegg, as always the best in customer service, exchanged it without issue. I always shop Newegg first when looking for computer parts.
Summary: Beware if you plan on waiting to buy your 2nd processor. Windows Vista, 7, and Server 2008 will not accept a processor that has a different revision number or stepping, even if it is the same model and has identical specs. It will generate a BSOD on startup. Windows XP Professional x64 does not have this issue, and tolerates the difference, but you know the compatibility issues you encounter with XP x64.
Pros: For the price, this is an excellent motherboard. Dual processor capability in an ATX form factor. It has a PCIe x16 slot w/ x16 signal, so it can accommodate a gaming GPU.
Cons: Had the old BIOS which does not support the new Opteron 4200 series processors. Limited space if using a larger CPU cooler like the one I bought. Not worth removing an egg though. Does not include the MIO sound card, nor does it have on board sound, so either use a USB headset, or buy the MIO, its $20.
Summary: * Takes bloody FOREVER to get through the BIOS checks - worse, takes a disturbingly long time just to get an image on the screen. I was positive that something was wrong the first time I booted my machine up. Nope - it just takes, seriously, 15s or more just to get the very first bit of POST up, and another... I dunno, 1m or more? to get through the rest of POST.
Pros: * Good price - dual CPU + up to 128GB RAM for <$300? Yes please.
Cons: * Socket C32 == hard to find CPU fans. Not that that's the motherboard's fault.
Pros: Board was DOA on post -- got keyboard not connected error. Requested RMA online but then decided to call customer service to see if there was a way to speed up the replacement process. Got an advanced return where I gave Newegg my credit card info and they next day aired my replacement board to me and they also payed for the return. Very good policy. Replacement board works very well.
Cons: Jumper description to disable on-board vga in manual does not appear to match my motherboard.
Summary: The processors are a little close. Fan mounting on the CPUs was a trick.
Pros: Tons of room. Stable. Tons of fan connections. Dual NICs. Fits in an ATX case. Works with SLI/Crossfire power supplies. (Double-check the specs). Nice mix of PCI and PCI-x slots. Nice spread out layout on the board itself. Thousands cheaper than a comparable Mac.
Cons: If you're using the upright CPU heatsinks with the fans (eg XIGMATEK HDT-S963), one fan will blow across the other heatsink, so you'll have one processor with a higher temp. Also if you're using the upright coolers the memory is under the edge of the cooler. There also aren't a lot of USB ports on this board. Most of the features on the board require an add-on card.
Pros: Running great.. Slapped in four 8GB Kingston ECC memory and off it went.. Fired right up with my 2 Opteron Quad Cores.. I know I could have used reg memory but this is my virtual server and I might expand the memory down the road to add more virtual servers...
Pros: ASUS has given me access to a new BIOS with on-board RAID working now, and it tested out alright. Mostly using it with Adpatec PCI-E cards, but wanted the flexibility of onboard raid as well, which is working now if desired.
Cons: Drop the PIKE and give me an extra PCI-E and make PCI-e RAID cards!
