Unstable reboot

[Tedster]

Running a 2500XP+ Athlon on an MSI K7N2 Delta 2 platinum
2 sticks of 512mb kingston pc3200 DDR4000 memory
1 stick of 512mb crucial pc 3200 DDR400 memory

Been running the FSB memory a 202 mghz for a long while.
Memory voltage at .270

Last night it started to reboot over and over.
I had to notch down the FSB to 200 to get it to be stable.

I am curious why this would happen.

increasing the memory voltage to .275 had no effect.
I returned it back to .270.

The computer is running fine now, but I am curious why that would happen all of a sudden when it ran fine for 2 months.

Maybe you've found the edge. After 2 months something has tipped the balance - maybe temp increased by a degree or two.

possible. I noticed it happened after I turned off the AC last night.
