First thing I look for its variation in max core temps. Just did a 24 hour Prime95 run at 5.0, 1.41v posted in the stable club. Warning: Spoiler! (Click to show)
Temps were 73, 77, 74, 73. If you are getting 10c difference after delidding then I believe you have some room to experiment to try to get an optimal setup.
(Also did a 24 hour XTU run since some crazy nut who misinterprets posts made by newbs suggested it.smile.gif Temps were noticeably lower during that run though.)

hmmm so what if i ditch the IHS all together and go for direct die, what are the odds ?

A few here have tried with some success, they can answer better than I. Many others have commented that it is not worth the risk. My simple advice is do what I did, take a few hours and try a bunch of times to see if you can get things better. Just enough TIM in the right place, the IHS sitting just right when clamped down, and the cooler installation in the best configuration you can find.

When I had my H100i the best by far was the block upside down and one side tightened before the other - it shouldn't be best like that, but it was the best fit for my particular IHS. If you think something you did to the IHS is making it lopsided, you need to test it to know. Look at the TIM fingerprint and interpret it, get some pressure paper, or lay the rig down so you can test if the IHS is level and flat while clamped down - it may take removing the mobo to see that though.

You may have to remove your CPU socket latch. On my AsRock board it sits just above the height of the DIE. If your heatsink or H20 block are to wide it wont make contact, and you will need to remove it or mod it.

edit: Just know that the only thing that will hold down the CPU at this point is the cooling block itself. You could find a way, I have not tried anything yet, other than trying not to forget its not latched. tongue.gif

Pretty high, 1.39v, so far 3 hrs prime stable. It only takes 1.21v for 4.6ghz, its quite the jump. Might be missing something, still learning the chip.

That sounds good to me. For 4.8Ghz my chip takes somewhere around 1.51v to be semi-stable. That is DMM voltage. CPU-z says it is 1.39v, but it sucks and it lies to me.

I have the same board, I thought I had a golden chip before I bought a DMM...Now I realize I have a slightly better than average chip and a crap board!

Yea man it is a total bummer.

So for my next question..... why is it that all of the knowledged people here just "happen" to have 5Ghz chips????? Me thinks you guys have some secret dead poets society where you hand out the good batch numbers. Yea! Thats right! I know about your little secret!!!!!

..............sorry. I have to be at work in 4 hours and I can't sleep for the life of me. Driving me nuts. I closed and got out 3 hours ago and now I have to open in a foot of snow in 4 hours. Brilliant!!

I guess the temps are making me timid. I never had heat issues with my 2500k under water even at its max of 5.3ghz and 1.55v, no matter what It wouldnt boot at 5.4 even with over 1.6v and single digit temps(window mod). I think it would have eventually done it, I just wasnt willing to push the voltage any higher. My Coollab pro just shipped, hopefully it will be here before the weekend and I can get the temps down where they should be.

Its all I use anymore for pretty much everything, I have no complaints. Anxious to see what the Coollaboratory Pro gives me, hopefully something closer to Sandy temps.

edit: Ok CPU never hit single digits, thats idle temps. Stayed around 30-35°C.
