Antec Nine Hundred Two Black Steel ATX Mid Tower Computer Case
You need to make sure you bought the MB that supports SLI (((I quote.... Four PCI-Express 2.0 x16 cards can be mounted for cutting-edge graphic power with support for quad ATI CrossFireX. Eight 3Gb/s SATA)))) I myself have Crosssfire And the Machine runs like a raped ape. My best guess is that you did not purchase the correct Video Card
Tes a single video card will cause that problem if it is not rated for that mobo ...The mobo he has calls for Crossfire Not SLI
It would be considered fortunate if he didn't cook the rig
SLI and Crossfire only come into play if multiple cards are being used. A single card shouldn't be causing these problems unless it is a chip set conflict. In theory as long as the card is PCI-E it shouldn't be a problem. You may also want to test each stick of memory individually or some mobos have to have the memory in DIMM slots 1 and 3 or 2 and 4 while others the usual 1-2, 3-4.
It is not going to be the power supply unless it is faulty, because even a fecal 900w PSU should be able to power a 9800gtx.
The mobo dimm slots follow away from processor as 1,2,3,4 Unfortunately while referring back to the mobo user manual page en-24 supports ati-crossfire technology No mention sli http://ocss.msi.com.tw they will tell you the very same thing this is an crossfire mobo
You should of got one of the new 890GX chipsets lol, they are sweet azz.
I am buying a PC and I have already spent a month just reading, and researching.
I don't plan on buying till maybe June, once I know what is going down with all the new technology, esp. since things are gona get out dated real quick. That mobo you pick is the same one I did and I honestly think its the best board out(for amd). But you got to look at the things it dosen't have: usb 3.0, Sats 6 gb/s, and HEXcore capable. The boards that are out now arent half bad, just wait a month and will probably see a 890GX-GD70!!!!
