Look like this is the most common case... the need of 1.4v to get stable at 4GHz...Quote:

I've bent pins before as well and a mechanical pencil works perfect. :)
That sounds like a good chip, the chances you are going to get something better are low.Quote:

Your i940 sounds promising, pump it up :up:

So I started working on the 27 multi with the idea that I could pick up some DDR3 2000.
So I have been able to get 27x159 prime stable with HT on - pretty happy about that actually (see below).
So if I pick up some new 3x1GB DDR 2000, I should be able to run it at 159x12=1908?
someone double check me but I think the .5v delta is between qpi v and ram v, correct?Quote:

rge - how are you liking F5e? Did it get you anything over F4j or m?Quote:

I have never heard that vcore needs to be set to anything vs qpi - intel max v that I know of -Quote:

Will be interesting to see how much more qpi/vtt I need for 6gb vs 3 of ram, currently only 1.31v for 21x200.Quote:

yeah, dont know that I will notice the difference, but I am one of those that has to try everything:p: I am assuming I wont have to go all that high, but that is one of the things I want to know, and best way to do that is try both. But I will run at 4.1 minumum regardless, preferable 4.2Quote:

4ghz @ UNDER 1.3v load with HT on in LinX @ 210 bclk? Something is fishy!Quote:

No, actually my chip does the exact same thing. I just did a 20 pass run maybe 2h ago. Same clock, same voltage. I used memory at 1691, 7-8-7-20-1T timings, uncore at around 3800MHz give or take a few MHz.Quote:

It's funny that OC with higher BCLK actually works better than higher multipler. Completly opposite of what we should be seeing.
No wonder all the chips basically clock the same across the versions (920, 940, and 965 XE).
concur - all chips about the same (I have the 965).Quote:
