Picked up a new retail E8400 and installed it last night. Batch was Q811A115. VID is 1.1125 as reported by Coretemp.
Installed it in my P5K-E motherboard with Swiftech H20-220 watercooling. Details are in my system specs.
So my resting point at the moment is 3920MHz @ 490X8 with 1.352V load. Max temp is 47C on both cores running Prime95 small FFT's. Ran successfully overnight Prime95. Ran 3 hours cycling through 3DMark06 so video is stable @ 490MHz FSB.
After reading about CPU degradation I am nervous about exceeding 1.365V since I don't want to kill my CPU just to get a few hundred MHz out of it. Even at 1.376V I was not Prime95 stable at the magic 4000MHz mark. I think that I am on the part of the slope where it will take significantly more voltage to get stable >4GHz so diminishing returns for me. The 4GHz barrier is more of a psychological barrier than a real one. Being 80MHz short of it doesn't really bother me.
A few observations:
Although Coretemp reports a VID of 1.1125V my P5K-E seems to set the Vcore to 1.2000V at default clocks. Is that odd?
I notice that "auto" adjusts the Vcore up as you overclock the FSB. I guess they program some sort of curve into the BIOS to account for overclocking?
So watcha think? Is this about average for this CPU? Good enough... or should I set it to (little finger at corner of mouth) 1 MILLION Volts...
