32 bit os by any chance
I don't think even those crap GPU's from both Vendors that use System ram when needed take 1GB.
Hmm You got a Memory Remap Option in your Bios ?.
Ah, thats done the job nicely.
Does that mean I've spent the last 10 months thinking I had 4Gb of ram, but only using 3? T_T
burns
what ram is it? what motherboard is it?
might need to up the voltage of the NB/MCH and ram (or bios update)
