What'd you graph that on out of curiosity?

thats weird, it looks like you have very high stock voltage... the stock on mine is 1.25... are you sure your bios are accurate?

Thread Starter 
I plotted this in excel, just did a simple two colum spreadsheet, clicked the chart wizard, line graph...done.

This is also a good example of my ever fading memory, that should have been 1.3525, not 1.325.

My E6600 box even says:

Version # D63625-002 1.35Vmax.

Newegg specs say votage is up to 1.3525 here:
http://www.newegg.com/Product/Produc...82E16819115003

Now if you're running speed step, it's supposedly able to handle voltage down to 0.85V. I've also heard of a few people running stock speed in the 1.2 range, but I never tested that myself, as my intent was to get good stable OC with Stable and some degree of cushion as priority over squeezing every last bit out of it.

doesnt really matter on how much voltage it has as long as its below 1.5-1.6...the processor uses as much as it needs.

Slap a water cooler on that baby and you should hit 3.5-3.6GHz stable =]

I'm at 3.6Ghz now.. I could do 3.8 stable if I wanted too but I'd lose performance because of the NB strap..

Good air goes a long way..

That's great. Rep +. Thanks.

As an electrical engineer, it's interesting. This happens because the signal is no longer clear enough at higher speeds to be read as a 0 or 1. Ideally you want a square shape, but then when you go past the limits, it begins rounding, so that the top of the electrical curve is rounded.

Increasing the voltage raises the curve up, so that it's above the "1" voltage for more time. What the heck, I'll plot this for you. At least, this is what I imagine is happening, I'm no CPU guru.

Top image = ideal

second - overclocked with no V increase - CPU can't read it as a 1. Signal attenuates.

Third box - V raised - CPU reads as a 1

thats kinda weird looking but i think i get what your getting at

Updated the stock vcore, and projected the vcore I would need with the limited data I do have.



From my estimate I'd need 1.49v and watercooling to reach 3.6 with my copy. Even with the Scyth Infinity, I'm getting up there in temps enough to know I wouldn't be comfortable without water cooling.

I guess in the end I just wanted to show that the increase in voltage wasn't really linear and the wall comes on more sudden than I expected.

Anyway thanks for the replys, this was one of the more fun OC journeys I've had.
