New Memory Gives Me Reboots

[lsamorph2]

I have a shuttle sn45g, amd 2500+, aiw 9800Pro, 512 crucial ram. I just bought 1gb of corsair xms (x2 512mb) and I'm getting reboots. One of the things I notice when i have the crucial ram isntall is that the FSB is at 266 and when I install the 1gb its at 400. Any help will be appriciated. thanks

is the crucial ram ddr400?

Certainly it's not the FSB (the CPU bus) switching to 400, I rather bet it's the RAM bus. Different thing.

www.memtest.org - your first stop after buying new RAM. Always and ever.

try setting your memory to 166 (ie 333 effectively). that should solve the problem. Havent come across 2500+ running at 400Mhz FSB...

Doesn't matter - if the chipset is capable of running the RAM at 200 MHz while the CPU is at 166, which isn't too uncommon today, then the RAM should be working just as well.

Run memtest at 200 MHz, and if you see errors, do it again at 166. Then decide what to do next - return the stuff, or keep it although it doesn't operate at its specified speed.
