Hello, I have a desktop homebrew, I've had for several years with a MSI K8NGM2 MB.
XP has been bogging down recently, running low on RAM. Right now simm1 has dualddr 512mb. I purchased a known good second, identical memory but no matter where I put it, it doesn't show up. Either stick, by itself, works fine but when the second is added it doesn't show up in bios check or XP.
Why can't the system find the added memory??

When you said identical memory, is the mfg part# the same?
With both sticks installed reset the bios with the jumper on the motherboard.
