Back about 3 months ago I took this system down and removed all the RAM, and stuck individual chips into it and booted it, testing each chip on its own. At that time every single one of them worked!

It could be a bad physical RAM slot on the motherboard. Try filling the slots one at a time (or two if paired) until you hit the problem slot.

It could also be a power supply problem... Add memory load, and a bit of heat, and voltage drops a bit...
