I have an ASUS A8V Delux MB which came with 1gb RAM in 2 - 512K modules installed in sockets A1 and B1. I purchased another gb of RAM (Corsair XMS matched pair) to add on. I moved the old module in socket B1 to A2 and added the new matched pair into sockets B1 and B2. It doesn't look like the computer sees the new memory either in BIOS setup or Hardware (control panel). Both still show memory to be 1gb. I made sure the memory matched what the MB used which is DDR 400 . I need some help to go from this point forward. any help would be appreciated

Hi there

Can you try moving your original pair of modules back to slots A1 & B1, then add the two new modules to the other two slots. See if that helps.

Thanks Samm - that worked. It was going to be my next step, but I am glad to have another opinion agreeing with me. It appears the MB recognizes memory pairs by slot number and not letter or color.

I'm happy it was my day to be helped

Glad its working. You are right - the pairs are determined by the slot numbers (in this case A1+B1, then A2+B2).
