DDR2-1066+ on AMD platform?

[imported_shortCircuit]

I have Fry's GQ6130 which has ECS 6100SM-M and Sempron 3200+. Initially, I wasn't planning on overclocking, but the CPU was running at only 1GHz and memory at DDR2-400 rate. After changing couple of BIOS settings, upgrading RAM to Crucial Ballistix DDR2-800, and increasing the CPU reference frequency to 283MHz, I got memory clock running at 566MHz (DDR2-1132), and CPU running at 2.55GHz! I wasn't sure if it was even going to boot since Ballistix requires 2.2V. nTune agrees with CPU-Z.

But Sempron is supposed to only support memory up to DDR2-533, and ECS 6100SM-M DDR2-800. So should believe what nTune and CPU-Z is saying? Or are both simply reporting the BIOS settings?

I would trust my life with cpu-z heh J/k but you can set lower multipliers if mem speed worries you, like 6:5 or 4:3

If your "FSB" is at 283, the memory is running at 566mhz..not 1132, so CPUz and nTune are wrong.

Thanks. Actually I'm more skeptical of the results than worried. Having DDR2-800 ram run at DDR2-1132 rate with only 1.8V is somewhat difficult to believe. This is compounded by the fact that Sempron only supports up to DDR2-533. So I'm running the memory at more than twice the CPU supported frequency with no errors or crashes. Not to mention I'm getting 70%+ overclock on the CPU with only 1.25V.

I guess it's a pretty impressive result for <$200 machine then. Maybe I should upgrade the CPU to Opteron 1212 to see how well it fares.
