So.... is "stock" Skylake useless under LN2 without a TIM-swap? Seriously.... a possible load swing of 160 degrees?

I dont plan to be voiding an warranty on a AUD$525 CPU though.

Don't need to de-lid for extreme OC on LN2. See for yourself.

 

 

 

Nive vid, though let it run something and you might be surprised... CPU-Z stability is not the only thing what we seek for :)

Problem is not in idle of course but rather in exhausting benchmarks and this i can think of xtu,cinebench,3dmark cpu tests.

 

In any case i would be very carefull when delidding this time,cpu has traces on all pcb unlike haswell where half of cpu was not in danger.Add the thinner pcb and you see what i mean.

So....you'll be running at stock, then? :D

At a certain point the stock TIM will give up and the frequency will drop down by 500-600 MHz on load. Saw this several times now with skylake CPUs.

Dancop also had a good 6600K which could run around 6,2 GHz first using the stock TIM. After few benchsessions he could not exceed 5,8 GHz anymore. Swapping the TIM with Kryonaut he could do 6,3 GHz.

Do Haswell and Devil Canyon also suffer from this?

No they don't.

Deliding there actually might cost you some frequency instead of gaining. This is only for Sub-Zero, ambient, deliding will help you.

I know Ivy lost frequency when delidded but I thought Haswell and DC didn't change at all, except that the cold bug may move a bit because of the different thermal transfer rates.

popped my cherry tonight and delidded a two chips no issue's. It's crazy how light the actual cpu/silicon substrate is in comparison to the ihs. All in all just use a razor blade, simplest method even for a noob like me. Thanks for this guide Splave.

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

 

What about after delid what were the temps like for LN2, did you still hit positive temps ?
