My FSBi s at 150mhz with all the timings set to 2. (I don't get any more stability from the slower timings) I am currently running the RAM at 2.9v I am wondering if this is too much power. It won't be stable though if I set the RAM voltage lower. The ram doesn't get warm at all. I have 1 stick 256mb pc-2100 Apacer ram
