[OCN] Kabylake-S doing 5GHz on Air

[FlanK3r]

Many of rumours were about 5 GHz validation. Validation process by pro-overlcockers ius easy step.Edit of CPU-Z.ini for less stress for Windows/CPU load. If the CPU is new informations in CPU-Z, example voltage readings is not correct (special with IVR inside the CPU). ANd next process is easy.
1)edit of CPUZ
2)Windows XP or Windows 7, both are tweaked for low system memory
2)disbaling cores or OC only at the best core/cores for validation
3)higher voltage than for stability (example 1.5-1.55V)
4)CPUZ qucik validation process, stability is only for few seconds, after BSOD, crash the PC etc

I know it as overclocker

But it is possible, Kaby Lake could hit up to 5 GHz stable with some pieces without delid.

There have been quite a lot of rumors about 5GHz over the years and many were untrue indeed, but you have to admit that a lot of Sandy Bridges did reach that easily even on air.
It was 22nm and 14nm that overclocked less, now 14nm+ seems finally promising, to the point that a stock chip on air is already at 4.5GHz (7700K at 95W) and another one is coming with even higher speed (Kaby Lake X at 112W).
I doubt that if the latter reaches say 4.8GHz at stock it won't overclock just 200MHz or more, plus given current Skylake average overclocks, let's put it at 4.6GHZ, a less than 10% increase could make 5GHz common again. They stated the process allows for 12% more performance, that seems to hold true for both 3GHz and 4GHz parts (core-M as well as high end quad got a 300-400MHz increase) so the same increase moving toward 5GHz isn't that impossible.

The 32 nm process seems to still be the best one for overclocking. Westmere Xeon's overclock like crazy as well.

5GHz+ and IPC over haswell may be enough to reire this 4770(-k) for VR duty.

Considering my 6700K tops out at 4.5GHz, I'm taking the "easy 5GHz" overclocks with a shaker of salt.

depends on, without AVX my best 6700K can handle 4900 MHz stable. With AVX stress less because temps

That's my feeling as well. My 6700k hits a huge wall at 4.4GHz so I pushed it a bit to 4.5GHz but that's as high as I can go without insane voltages.
