Hi,

My motherboard is a Asustek S775 Intel 975X ATX

I have bought 2 new sticks of RAM together (2GB each) and if I try them 1 at a time they work OK but if I put both of them in together it doesn't recognize both of them, the physical memory doesn't go up.

So I have 4 sticks in : 1GB, 1GB, 2GB and 2GB the physical memory in Windows task manager is 3455MB (I think its about 400 MB lower than you'd expect because the graphics card takes some of it.

My Windows is 64 bit.

Thanks,

Paul

Some further info, in the BIOS is says this :

System memory
Total 6144MB
Appropriated 640MB
Available 3456MB

I have updated the BIOS to the latest firmware, but it hasn't helped.
