My W7 64bit only detects 4 out of 8gb of RAM...

is there any further information i can provide to allow someone to help me out?

What is your windows version?

U need to have a x64bit windows.

i wrote it in the title, but it's listed as

Operating System
MS Windows 7 Ultimate 64-bit


In the Computer - Properties window it states:

Installed Memory (RAM): 8.00GB (3.74 Usable)

Is it unchecked in the msconfig, the max memory?

The max memory box was not checked. I checked it and increased the number to the max (8192). Then I applied and restarted my machine.
Now, when looking at the msconfig-boot-advanced, the checkbox is checked but the number has reverted back to zero.

I can post screenshots, if need be.

No, not needed.


Can u run the Memtest or Windows memory diagnostics?

I will run both when im done with class this evening and post results.

thanks!

Ran memtest for about 1 and 1/2 hours with no errors. Havent had a chance to run the mem diag tool yet.

Would this help? In my resource monitor, all 8gbs is listed but theres a 4gb Hardware Reserve...

:sigh:
i switched the modules slots around in the machine and its working fine now...
thanks for your time!
