Win7 64bit not seeing all 8gb of ram

[Yousuf Khan]

Ok folks an update here with what I have done to solve this minor problem.
I did some searching on this and found some information which said
something about going into msconfig/ boot/advanced, and untick 'maximum
memory'

Any idea what the "maximum memory" option is about? How did it get
ticked in the first place?

Oh, I just tried it in msconfig, looks like the "maximum memory" is
probably some kind of debugging option, to limit the amount of memory
that the system sees. I assume it's to test programs in differing
amounts of memory.

I would never have thought about going to msconfig to see what was going
on if I didn't see the post in a forum I stumbled upon.
I have no idea what this 'maximum memory' means there either.

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.
