Yes, prime stable. Volts are 1.55v. It will do 2.3 GHz on stock volts, 2.4 GHz on 1.45 volts, and 2.5 at 1.55 volts, but that's pretty much the wall right now. I'm using the stock HSF. I may end up getting an aftermakret heatsink and pop the top of this cpu. That should allow me to lower the voltage a bit, or sqeeze a few more MHz out of it. I'm pretty happy the way it is right now. The T-Force is running 313 fsb. The computer will boot with the cpu all the way up to 2.7 GHz, but it requies WAY TOO MUCH voltage to make it run (1.7-1.8 volts). It will run at the stock 1.6 GHz with as little as 1 volt.
About the Biostar: I has the most overclocking options I've ever seen on a board, especially one this cheap! The biggest pitfalls I've found were the heatsinks and the auto detect ram timings. the IGP simply needs a fan on it, b/c it gets pretty damn hot. The 410 chip (um.."southbrige?") has a pussy heatsink on it as well, and that thing will get up to 47 C in a close case. That is even after I put AS5 on them. I would actively cool that chip as well, but my video capture card is in the way to prevent the mounting of a fan. The ram timings need to be set to manual for everything, even if you change nothing, otherwise it will tighten up the timings on your ram if you knock it from the 1:1 to another divider, causing the sytem to fail to boot and other probs once you clock the frequency back up.
I found the software o'cing and monitering utilities to be crap. The vcore settings in the bios dont match the actual vcore, sometimes by as much as .5 volts! The Biostare software System Moniter temps look too low. When idling in the bios, the temp is around 36 C. In windows it reports it as 29 C. To "fix" this, I simply set the alarm to 46 C (which would be 52 C, if the bios/windows discrepancy be linear). The disturbing thing I've found so far is the bios updating. I attempted to flash the bios through windows and through the biose utility program. Both tell me they were successful, but the bios date on the post screen never changed. Add the fact that the T-force bios update webpage has been FUBAR for the last 3 weeks, and the situation gets a bit more annoying.
Overall though, I am happy with the system. I achieved the goals I wanted. I just wish I didn't have to feel like I am beta testing this board.
If anyone is wondering about the 6100 IGP, it scores a bit more than 10K in AquaMarK3. I did the test with stock cpu settings and max o'c settings...the score was pretty much the same. So, it'll beat an FX 5200, but not an FX 5200 ultra. 2D graphics are of course exceptional.
