Hi Everyone, Ok this is just weird. My computer, it appears, is plagued with problems. The latest: I had two sticks of Kingston 1GB DDR2 RAM, both PC-5300. They looked physically different but were rated the same specs - and worked in dual channel mode just fine. Anyways, I RMA’ed one of them because it was giving random errors (confirmed with Memtest). The new RAM stick came in the mail and after installing it, the computer shows me I’m running single channel?! The things I’ve done so far: - ran Memtest over night, no problems - Tried changing slots from B1, B2 to A1,A2 (putting the RAM in the slots as per the manual instructions) - Putting the RAM in A1, B1 - Putting in one stick, booting in windows. Turn off. Installed the second piece of RAM - BIOS update to latest version Um. What’s going on here? Btw, one stick is double-sided while the other is single sided. Don’t know if that makes a difference. Any help would be great! Thanks.
