Non-Overclocking Question

[Wheeler Dealer]

I just purchased a new CPU/mobo combo, and I have a question.

The CPU is an AMD Athlon XP 2600+ with an ECS L7S7A2 motherboard, and some DDR/400 memory. I don't want to overclock this, but the only way I can get it to be stable seems to be to underclock it...unless something else is wrong

When I put the CPU in, they system defaulted to a frequence of 133, and the BIOS reported that I had a XP2000. It also defaulted the memory frequency to match the CPU.

If I up the CPU frequency to 166 and the memory frequency to 200, the BIOS reports an XP 2600+, but when I perform CPU/memory intensive tasks (like video editing and rendering), the machine freezes. If I reduce everything back down to 133, the computer is stable as heck.

Am I doing something wrong? Could the CPU be bad? Should I leave the memory at the same frequency as the CPU (at 1666)...help...I don't know what to do?

TIA

is that a normal 2600+ or a mobile 2600+?

and is it a 266 fsb or 333 fsb 2600+ if it isn't a mobile one?

Looks like 2600+ should run at 166/333. Synch your ram at that speed too.

Don't know what mobo you got. First check your manual for setting ram FSB to "auto" (may be called cpu/dram ratio). Prolly in "Soft menu" (if you have that) or "advanced chipset features".

Run the memory in synch with the fsb (166/333). If that doesn't fix your problem, back off the memory timings (i.e. set them to larger numbers) and see if that helps.
