RAM Problem

[ctjoyce]

My laptop dosnt want to accept RAM in dual channel, when it did fine before. Now it will accept it in single channel, but when I put in a second stick, it dosnt boot. I need help and fast

Swap sticks and see if one is actually bad?

If not, maybe a slot is bad?

Try fitting it a few times with attempts to boot each time, might be a dodgy slot.

BIOS reset needed ? (doubtful).

Ya i think i may have a faulty slot, as i have tried three different sitcks in there, and none work. I also upgraded my bios, so that might be a problem too.

 Well a failure after a bios upgrade would indicate a stinky bios right?

Did you upgrade the BIOS because you were having problems, or just on a whim or bad advice?

For dual channel to work, the bios must support it.

Also, ideally, the memory sticks should be identical in terms of speed (ex. ddr400), memory amount (ex. 1 gig) and type (SDRAM).
