Windows only able to use 4GB on 8GB RAM

fuzedzn
Go to solution Solved by Xsilent(X),

then you have a damaged ram stick! try to pull one out and see if it boot if it boots pull that out and place the other one in and see if that boots to. if they boot both then there might be something wrong with the northbridge

for reserved ram :

 

msconfig.exe -> start up -> Advanced Options -> Check max ram and set it to 8Gigs -> reboot

 

If this does fix the error, you're fine

 

If not : i have no idea

Tried this.. Nothing :/

Ok, Checked bios.. RAM is running in Single Channel Mode when it should be in Dual Channel Mode

Try another OS version which is certainly in 64Bits. it will work

You can also try a BIOS reset :)

It's just going into BIOS and pressing default settings...

try to deactivate all bootup software and start one software boot @ a time and look always to your ram usage when enabling a software.

List of things done:

BIOS Flash

Swapped Sticks to different slots

Made sure MAX MEMORY was unchecked in msconfig (also tried with it checked)

Tried redoing windows index (Read some forums saying that fixed it for them)

Booted into Ubuntu to check if it had access to 8GB (still only 4GB)

then you have a damaged ram stick! try to pull one out and see if it boot if it boots pull that out and place the other one in and see if that boots to. if they boot both then there might be something wrong with the northbridge
