Anybody have any idea what's the maximum safe voltage for an Athlon64 chip is? The older Barton/Tbred seems to handle 1.80-1.85 no problem. The Athlon64, same 130nm process, however defaults at 1.5V could it handle up to 1.8V for a period of time let's say 2-3years?
If you look at overclockers.com u will see that cpu's in their database are going as high as 1.85v with good aircooling, 2v+ with water or phasechange.
Another advantage of the mobile chip thats not often noted is that its max temp is rated at 100C, not 85-95 like normal ones.
One suspects this is cauz they are hand picked chips and HAVE to endure higher than normal chips given a laptops generally inferior cooling solution.

i would guess, but not guarantee, the chip would survive 1.7v or even 1.8v for extended periods of time. Be carefull increasing vDIMM though, A64's are sensitive to this, and many motherboards will severly overvolt vDIMM for short periods of time (high fluctuation), possibly killing the ODMC, and therefore the cpu.
Also, A64's don't tend to gain all that much from overvolting, you could try it, but if it doesnt yield much better results (what I'd expect), just decrease it again.

Well on my mobo there are quite a few voltage options, there's the VHT, for Hypertransport, the VDDQ, not sure what's that for, I didn't need to raise the vdimm, since i had to use the CPU/12 Divider. Anybody has any idea what VDDQ is?
