I tried it with one core enabled, and I didn't see any change. And that wouldn't address the other end of the issue, which is that the clocks are supposed to be lower the more load there is. That is unless Turbo works differently these days. With a 2600K, for example, it was 3.8GHz for one core loaded, 3.7 for two cores loaded, 3.6 for three and 3.5 for all four (at least in theory - in practice you almost never saw 3.8, probably for the reason you mentioned above - but the fact remains that at full load it dropped the clocks). I'm assuming that Broadwell-E isn't supposed to be using 3.8 for 6-core loads.

Yeah, I run at 3.7 GHz with 1.26V. But uncore frequency has negligible impact on performance, you're not missing out much (if at all) leaving uncore at stock from what I've seen.

Hey,
I'm new here and was just reading over some of the previous comments about some of the 6800k overclocks and now I'm wondering if my particular chip is a freak or something is wrong. I was able to get a stable overclock at 4.368Ghz, even have seen it boost to 4.37 (I know not much of a difference) but I haven't even touched the voltage. Voltage is sitting at 1.287V. Temps stay in the 40s for the most part, occasionally hitting 50C when under stress testing for extended periods (over 15 mins).

Parts:
i7-6800k
NZXT Kraken X61
ASRock Fatality Professional Gaming i7

Yay another good 6800K!

Aim for 4.5ghz. See what 1.35vcore will net you with

I'll probably try that tomorrow since it's my day off. If it's stable then I may leave it.

I have 2 questions:

the overclocking sockets with additional pins on some boards, in my case Gigabyte X99P SLI, is it safe to use it? And is it any useful for standard overclocking (by that meant no LN2, DICE etc...,rather standard 24/7 clocks, 4,5GHz top, if possible)

The other thing, the pre-applied paste on the Corsair H105, should i use that or another aftermarket TIM? Specifically, i was given for free with the CPU Arctic MX-4. Which one to use?

Thanks

Of course they are safe to use, otherwise they wouldn't even be sold. All high end one from ASUS has the OC socket since HW-E release and it's useful for cache overclock. But on BW-E, it doesn't seems to help much in that regard.
Best TIMs to use right now are Thermal Grizzly Kryonaut, Gelid Solutions GC-Extreme and, if you don't want to spend alot, Noctua NT-H1, it does the job. There are some other good ones out there, I've tried those 3 hence the fact I can recommend them.

Per the link i found now while googling, the pre-applied paste is apparently on par with the Noctua NT-H1 u mentioned...so i guess, i just stick to it.

I Recently Upgraded to a 6850k and an Asus Rampage V edition 10 mobo .. Although i had my reservations as the board had many bad reviews, fortunately its issues have been resolved in the latest BIOS. first thing i did was flash the bios, reinstall win10 and updated the chipset version... i only turned on the XMP profile, rest everything is on stock .. these are my screenshots of CPUz, timespy and firestrike scores .i Plan to OC my CPU but do not know where to start and what voltages to put frown.gif , as i have heard stories of people burning there broadwell chips by giving them to much voltages

That's a quite good sample, but nothing is wrong with it. My 6800K i used before switching to a 6950X could hit 4.4ghz at 1.3v and could hit 4.5ghz at around 1.4v.

So yours appears to be pretty similar to mine that i had which was one of the best of the best (bought it as a 4.4ghz bin from silicon lottery, he said it was one of the best he had seen so far) considering you're "only" using a Kraken X61 cooler and i'm using a full water cooling setup with both a 480mm and a 360mm radiator, i imagine if you were to move up to a bigger cooling setup you would easily be able to get the same 4.4ghz at 1.30v that i could.
