Safe Voltage

[mk17]

I was wondering about safe volt levels. I understand that high-volts will damage a cpu more than high-temps.
My current setup is X6800, 310 * 11, yeilding 3.41GHz with 1240 System Bus. Volts are currently 1.4813 VCore, 2.05 DDR2, and 1.55 MCH.

[edit]
I only bumped these recently after testing showed instability on air

I'm running an Abit AW9D-Max, 2GB Corsair XMS 2 (and 7950 GX2), with a Corsair HX620 PSU, on air with an AC7 Freezer. Temps are typically 40c idle pushing up to high 50s during S&M cpu/ram testing.
Super PI doesn't seem to stress the system very much with temps near idle, scoring 16m01.375s for 32M.
Do these levels sound good or bad to you guys, what are you running for similar setups? And most importantly, will this take years of my cpu's lifetime?

Thanks.

Its unknown how many years the overvoltage will take off your cpu as the life expectancy is unknown. A cpu dying from volts is rare unless you go above 1.6v. I have had mine past 1.65 and this is considered dangerous. I wouldn't go above 1.55 on air though - depending on cpu temps.

Your 'levels' seem fine to me and are pretty average scores, try using Orthos or Prime95 for a longer stress test. S&M is also good but I generally use that for finding the highest temps rather than instability as prime based programs seem to be more sensative to stability faults.

Thanks for the response. S&M reported just fine for me, however a run of Orthos last night (on small FFTs) pushed the temps to mid 70sC after only 5 mins or so. I dropped to 1.375v on the board - uGuru sometimes reports slightly higher volts, I think on-demand.
I'm still at 310*11, with 2.0v on the ram, and 1.55v MCH. Then I ran Orthos for four hours pushing only into low 60sC. I think I may leave it at this . Normal tests (non-Orthos) push late 40s to low 50s now, worst case.
I think I'd need better cooling to push the voltage, although the side of my case is off atm, so I think this might reduce the airflow benefit.
I'm pretty new to this building/overclocking business, its highly addictive trying to find the safe-limits. Not to mention time-consuming. Thanks again.
