Ironically enough, the 45nm Core i7 (Socket 1366) Absolute Maximum Vcore still seems to 1.55v Page 22 and the maximum VTT seems to be 1.35v, which is a little scary for me in particular.

The 45nm Core i7/i5 (Socket 1156) have an absolute maximum Vcore of 1.55v (Page 67) and a Maximum VTT of 1.21v, which is extremely low in my opinion. I'm not saying it is wrong, but overclocking these chips under that VTT requirement doesn't seem to allow much overclocking at all.

I'm still personally keeping my i7 under the 1.45v Vcore maximum, but the 1.55v maximum listed has been up for a few months and has not changed. I'm really beginning to think that they managed to increase the maximum voltage for 45nm chips with the new architecture.

Whoa. That is indeed pretty low.

Lower is always better, and if you're on air cooling, you'll probably not get high enough clocks to need 1.55V anyway.

I was referring more to the 1.21v VTT cap on the socket 1156 chips.

Oh, I was just commenting on the "scary" 1.55v vCore / 1.35v VTT. I should have quoted.

Scary for me because I'm currently at 1.44375v(Bios) VTT with a max of 1.35v. When I checked this with my Fluke, it reads as only 1.402v so it's not horribly high, but is too high. My vcore on the other hand is 1.443750v (Bios) with 1.440v (Fluke).

You're above what many people would get on air cooling though I myself chose to go the other way and I'm running 0.944v vcore which is 0.768v at idle (going off CPU-Z, but it can be rough when undervolting anyway)

.

it's just to scare us all, been running 1.45 for a few months now, still going strong. With a 920, you'll lose a memory channel after a few months @ 1.45+ most of the time. Only time will tell!
