Running Vista Business on DFI Infinity 975X/G with 4Gb of DDR2-800. For some
reason the bios reports the full 4Gb but windows only ever reports 2Gb (I
know the GFX card would take some but I was expecting approx 3Gb).

Run MemTest86 tests overnight so it's not the dims.

Any ideas?
 
if I see this question one more time..............................do some
research on Google
 
Sorry BigJim. I had looked on google and changed some of the options in
bcdedit which was why I asked.

Current config is:-
nx - OptIn
pae - ForceEnable
increaseuserva - 3072

Were there any settings I missed?

BIOS settings. Enable memory hole.

Also, running the x64 version will allow you full access to your 4GB
without any 'tricks'.
