This soltek board wasn't intended for hardcore overclocking, which I fully knew when I paid the price for this. Paired with my generic Samsung PC3200 RAM, I did a mild overclock of raising my HTT Bus to 219, and leaving the multiplier at 10 with stock voltages for cpu and RAM. RAM and CPU are still running synchonously.
I tightened my RAM timings from 3-3-3-8 2T to 2.5-3-3-10 1T (tRAS of 10 is said to be optimal according to Anandtech on A64 systems)
Prime95 stable for 16 hrs. I can't push 220 HTT Bus without getting a Prime95 error in about an hour. I'm pretty sure it's my RAM holding me back. I've thought about running my RAM asynchously, but I satisfied with my current system power and I will consider such an option at a later date.
Oh, I do have Cool'n'Quiet enabled as well. As long as you leave your CPU voltage at stock, CnQ will have the ability to lower CPU voltage as necessary. I'm not sure if changing the mulitplier affects CnQ or not, I haven't tried it. raising y our HTT Bus certainly does not affect CnQ. (except that my lowest CPU speed is now 1.1GHz instead of 1GHz)
