I'm not sure you've proved that yet!

A summary of results - tell me if I have this
wrong:

Working sometimes:
2 x 512MB
1 x 512MB
1 x 1GB

Not working:
2 x 1GB
1 x 1GB, 1 x 512MB

My guess is still with a DIMM socket contact
problem, or perhaps a motherboard limitation.
What's your motherboard model?

I had a similar problem with a machine I built a
while ago. Two 512MB DIMMs - fine. Bought two
Crucial 1GB DIMMs and fitted them - no boot.
Turned out to be a mechanical DIMM PCB tolerance
problem - although the socket lugs were engaging
on both modules, they weren't sitting it the
bottom of the socket. Removing a fraction of a
millimeter of fibreglass was enough to fix the
problem.

Not uncommon, even for big name manufacturers.
It's a commodity market.
