VIA stability problems

[SneakyStuff]

Hey guys, my cousin has an Athlon XP mobo, made by gigabyte, and the model # is: GA-7VT600-L

Anyway, he seems to be having some trouble as of late, and I notced that when I was at his house, there was no way to overclock through the BIOS! Is there any way he could improve stability? Or somehow get overclocking in the BIOS? I find it very strange how simplistic the BIOS is.

EDIT: To be more precise, any overclock at all, on his AXP 2600+ Barton, results in instability, and he is having "Memory Leak" problems. That seem to be resolved when he switches the DIMM position from time to time. The system itself is quite cool, with 2, 120mm fans, one for intake, and one for exhaust, and his ambient temps are good too. I am clueless.

I've built systems around this board and can't recall any of the instability or memory leakage. This is after a dozen systems built around this board/chipset. I also used generic 4layer PC2700 DDR memory(PCboost.com Brokergrade) in the systems as well. Systems went out to clients and haven't come back since. Did he/you upgrade to the latest BIOS?

Yes, I told him to get the latest chipset drivers, and BIOS. He is still haing problems, do you think it is his windows install?
