Re: Super Pi 1M Rankings
Are you picking up a Phenom II X6 anytime soon?
Yes, within a few days probably (just a matter of where I get it, who has stock, what price)
Holy voltage! Does it really need that much above 3.8? I ran my Linx run at 3.8 with stock clocks (

at 3.8 it can run at stock volts, or 4GHz with ~1.475 (24/7 stable). ~1.425V is 99.5% stable at 4GHz (but it can get random reboots after a few/several hours).
When clocking much higher than 4GHz, you need more volts and/or or lower temperatures.
At ~20ºC, 4.4GHz can be done at 1.65V. But at -40ºC (dry ice) it could probably do it at ~1.525-1.55V
Though in my case, the board isn't making it easy, because of the vdroop (~0.05V). Also, it won't allow voltage to be set any more than 1.7V in BIOS (absolute limit) - which is what gave me the ~1.66V you saw in the screenshot - also, the volts varies a bit under different loads.
In any case, Phenom II's are quite tolerant to voltages compared to Intel CPU's
as long as temperatures can be managed properly.
It will definitely affect power consumption, and overall lifespan of the CPU can be affected e.g. it might last 8 years instead of 16 if you're running it at 1.6V all the time - though the board is generally a lot more likely to die before the CPU does (>=1.6V is a lot of strain on the board's power regulation).
