This worked for me, I did a RAM upgrade in a x-64 machine that had 3 strips of 2 Gb RAM, for a total of 6Gb working fine. Added the identical Kingston CL9 with an empty slot, and immediately got the 8 Gb intalled, 3.2 Gb usable situation.

Long story very short:

Boot to your BIOS, note all your settings (if you ever changed anything), then reset the BIOS.

Save, exit, and reboot to windows. It can't hurt and might work for you, too.

I think it might be something like (in this case ) going from 3 strips to 4 changed the configuration to dual-channel, and the BIOS got hung on making the changes. I don't know, but reset BIOS did it for me.
