Looking at this a little more carefully, the memory itself is fine The problem is _where_ it is being mapped into the address-space at. The first line is the give-awy ".... above 4GB ignored." At this point I'm *guessing*, but it looks like 'main memory' is gettnig mapped into the address-space in 1gb chunks and there is "something" (probably video memory) occuping space up to 0x?38000000 maybe a 128mb video card mapped in at a base 768mb If there is a way to relocate where the (presumed video) memory is mapped, say, down to a bae of 128mb, you could potentialy pick up 640 megs of usable memory. giving 3-3/4 gig less a bit, instead of barely 3 gigs. It's worth checking the video board manual and/or 'configuration' utility for a tweak.
