RAM problem - ASUS P7P55D

[mrkz]

Hello.
I have a problem, I have 4 sticks with 2 gb ram on each.
It says my computer is only using 4 GB out of the 8 I have.
My motherboard is: ASUS P7P55D
Its in Norwegian, but I guess you are able to understand it.

Screenshot of the 8 GB (4 gb can be used):

try reseating ram

Did windows previously recognize all 8 gigs of ram? What is the GPU?

Well it seems like reseating the RAM made it work. I believe one of those "pins" which are supposed to keep them on place is a bit loose or something. But anyways. I absolutely didnt believe that was the fault. But thanks anyway, its working correctly now
