Ok here's the lowdown 4 months ago or so I got a box full of PC parts cheap ( Christmas came early ). So I decided to test what I could and get rid of the rest to recoup what I spent. Anyhow a socket 7 board went off to a buyer (PCpartner to be exact). The board was tested it seemed to boot up fine no problems. Told the person if anything goes wrong within a week or so let me know. After a week everything was fine. 4 months go by and he comes back saying the board doesn't take simms!?! I stuck in two 8 megs I had lying around ... and voila it passes POST. Stick in non-parity chips and *bzzz* wrong answer. Anyone ever experience this type of an error before? If the slots were shot it shouldn't take anything at all. Bios problem? Board problem? Let me know ... otherwise I'm going to either have to bite the bullet give him $20 only a $5 difference that what he paid for the board or rip my server apart ( which I don't want to do ). Calling out all PC gurus I need answers and soon! Cheers!:frown:
