Reference For Die Size and to show no FIVR in the way.



Test Used:
Wprime1024 5.1ghz 1.48v

Before: 96C hit and failed within seconds (hard to tell what load after 2 minutes would have been probably 105+)
After: 78C Warmest core and passed thumb.gif


Under ln2 without Delid running XTU we are going postive temps at -145c hits 20c loaded. redface.gifredface.gifredface.gif


So I would suggest everyone delid Replace TIM under IHS and then put IHS back on.

The PCB is thin and Ive heard of it breaking in a vice, so I would stick to razor. Press in on each of the 4 corners then do the sides last.

Vice method fail (not me lol)

Also would suggest if you plan to let the ihs float instead of resealing (so you can keep it fresh) loosen the hold down first so you arent forcing the ihs to slide forward under pressure, then tighten the screws after brining the lever down


Also although they look identical, seems that skylake's IHS is a bit heavier than devil's canyon. Kind of interesting

EDIT: some more experience

Sorry for my Ugly hands tongue.gif

Here is a delid...



And Lap....Using A Clamshell to hold it freely as to not put any downward force in it besides its own weight.



Light Lap not even down to to the copper..Im sure there is very small concavity left which is fine I just want to lower the edges a bit.



And Inside Polish....



My Modest Water Cooling Bench Setup



XTU 5GHz on water smile.gif with really nice temps.



Small disclaimer this is in my basement. 21-22c idle temps, 19c ambient temp.

Interesting. That should make it significantly easier to delid than previous generations. What cooling was that WPrime run done after delidding?

So the PCB is thinner then on Devil's Canyon and Ivy Bridge? Fewer layers? Vise only method might not be a good idea then.

Looks like a huge difference though in the Delta after delidding - comparable to the previous generations, if not bigger.

How does it sit in the socket?
Will ANY cooler still make contact without the lid?
or refit the lid with something GOOD in there?

Put something good in there is best, IHS is better than without and much safer.

Ek have told me the naked ivy mounting kit should work on this cpu without sticking the lid back on.

Is there any reason other than safety not to put the IHS back on ? Shouldn't it be cooler WITHOUT putting the IHS back on, and just running direct to die ?

I've found it depends on the board.

I have two Z97's and the bare die mount on the EVGA throws a E55 code every time with more than 16GB and the Asus does not for some reason.

I'm an educator .....Common sense isn't something you are born with (trust me, I've been around people born in IL for 30 years and I see it everyday) but you learn ..... if you've not learned do not it blame others look upon your current educators and parents ....... it's not others responsibility to make sure you succeed or feel good about yourself that is something only you can claim responsibility for.

You can't offend me, I'm a realist. wink.gif

Come on Intel; this is still necessary? And we're forced to do it the harder (razer) way now? :/

Also, that's a really small die. Pentium G3258 for comparison:
