I've recently tried to add a second 2GB RAM to a computer. I bought a pair of OCZ OCZ2P8002G and added them to my BioStar GF8200E motherboard... Unfortunately Windows 7 x86 only showed 2GB available. I took a stick out and tested it in Slot 1, it worked. I took the same stick and tested it in Slot 2 and it wouldn't boot (or even reach BIOS). I put them both back in and the machine then refused to boot in the same way... weirdly.
So now I'm stuck with a machine that will only boot with one RAM stick, limited to 2GB. Very annoying.
Is my motherboard just broken? Is there anything I can do?
