Lock up with max RAM

Specs: Windows XP
I am using an Emachine T1220 with a Lomita MB. A short while back I upgraded the RAM from 256mb to 512mb, the max for the board. Unit runs fine for a while then freezes. Dropped the RAM to 384 and everything fine again. Picked up different pair of 256MB sticks and freeze problem returned so it is not the RAM. Is there a known problem with the Lomita MAT128401 motherboard or possible CPU (Celeron 1.2G) deficiency? Is there a bios setting that requires manual change when installing max RAM?

"Picked up different pair of 256MB sticks and freeze problem returned so it is not the RAM"

Until you test the RAM with memtest86, memtest86+ or Windows Memory Diagnostic & it's found to be 100% error free, you can't rule out the RAM as the problem.

And unless you're getting the RAM extremely cheap, you're spending too much on an outdated system.

Indeed, the memory was not expensive. As for memtest, the first supplier did say the sticks he supplied were tested. However, the Kingston part numbers on those were not what Kingston recommended for this machine so I aquired the second pair. Since both pair of sticks make the machine freeze at 512mb, I have to presume that the problem is not in the RAM. If I use one 256 and one 128 stick, everything runs fine. I'll swap the processor next and if I still have the problem, it will have to be the mobo.
And yes, processors are cheap too.
