Could you have by accident installed 32bit windows? I know you said it's x64 but it sounds like you're pressing that 4gb limit (~3.25gb addressable)

I can confirm it is indeed x64 via the Control Panel's basic system information. I have the same distro installed on two other rigs, one of which is an Intel Bad Axe 2 seating 1 390x, 1 290x & 1 290 w/ 2 x 1 GB + 2 x 2GB where all 6GB are properly allocated and the other from vague recollection is an Asus P5b also on socket 775 with 2 x 2GB where only 3.25GB is usable as indicated in the motherboard's manual.

Could you humor me for a sec and run cpu-z to see what kind of processor you're running? Just a quick search on the pentium d and there are conflicting answers that some pentium d's are only 32 bit capable. (also the p5b should be able to handle 8gb of ram) You can install a 64 bit OS on a 32bit only processor. I've done it on accident, I put W7 x64 on my dell mini 9 and it worked for what I needed it to do. If your processor is 32bit that would answer the 2 problems, 3.25gb of available ram and not being able to run this 64bit miner.

I'll get back to you as soon as I can. I run multiple 64-bit applications on this sytem and like I have said many times now, if this would truly be the issue, I would have never been able to use it in the first place.

Some intel chipsets from 775 era show less ram if you install more pci devices like more graphics cards. Try to boot only with one graphics card and see if it's only 3.25gb or 3.66, 3.75...

The 290x is the only GPU present in this system.

I built a new rig with only 2GB of ram and it wouldn't start anyways, just wondering what the point of the DAG loading only on GPU is ?
