All I want is an average chip (maybe a bit above average), but I never seem to get those. I always just stuck with the below average chips I got. frown.gif

Thanks for the quick responses by the way. I appreciate it.
If you're up for delidding and metal TIM under the IHS you can drop temps quite a bit. Delidding and CL Pro allowed me to go from 1.375v/4.7 to 1.44v/4.8, so you should probably gain at least 100 MHz headroom. I suggest using x264/HWBOT x265/RealBench etc instead of P95 for testing, though. But even 8K fft's don't get my cpu hot.

I started testing memory just to see if my motherboard was the issue and I noticed VCCSA was at 1.15 and VCCIO was at 1.15. I saw the posted numbers in here made it safe for up to 1.25 VCCIO, so I tried 1.2 to see if that would make that memory speed work, but it refused to post with a code 19 (Problem related to memory). The motherboard (AsRock Extreme6) apparently doesn't reset the settings and I'm forced to reset everything. Could the board/memory be bad if it can't even handle 1.2 VCCIO? Really hate building new PCs since it all feels like a crapshoot.

Don't know...I have 2666 RAM OC'd to 3200, but my board compensates the VCCIO/VCCSA pretty good on it's own so I leave them on Auto. Max readings I get are VCCIO 1.24V & VCCSA 1.216, with the DRAM set to 1.39v. Find someone with the same RAM and see what they are getting? I confess I'm not a RAM guru so can't help much with settings.

seems to be i could stable a 4.8 Ghz OC on 1.414/1.424, but i tried 4.9 Ghz on 1.454/1.464 and it crash...
any tips?

just changed vcore and memory voltage to manual 1.35v
turned off c-sates, virtualization, etc...

My motherboard is weird. For some reason it will set the VCCIO to 1.22 and the VCCSA to 1.21 with a 4.5ghz overclock with things set to auto, but if I try to manually apply those it just won't post like it's putting way more than is necessary. Now I have it set to 4.6ghz@1.375 VCore and it's running fine, but both VCCIO and VCCSA are at 1.18 now. I would rather set those manually, but apparently I can't.

I should probably test the memory at stock to see if the DIMM slots are messed up or something or possibly the ram, but I don't know what's a good way to test skylake. In the past I just used memtest86+, but I don't think they support ddr4/skylake, so I don't know how good the test would be?

My first i7-6700K can only do 1.280V@4.5GHz. Failed x264 and already thermal throttled up to 1.360V using a Hyper 212 EVO.

A second sample can do 1.265V@4.5GHz, or 1.300V@4.6GHz default cache or 1.315V@4.6GHz/cache 4.4GHz, also switched to a Phanteks PH-TC14PE.
Tried up to 1.420V and still failed 4.7GHz.

All tested using x264 stability test, Sync All Cores, LLC@Auto@Level 6, XMP enabled and everything else auto.

Should I stop the silicon lottery and keep the second one? I aim for a daily driver at low noise levels. From the statistics in the first page 1.3V seems to be a good voltage for 4.6GHz.

My setup:
ASUS Sabertooth Z170 Mark 1
Phanteks PH-TC14PE
Corsair DDR4-3000MHz 8GBx4

Use memtest for the ram and open up a copy for each thread (4 for 6600K, 8 for 6700K) and test to at least 200%. But only use 95-96% of available RAM.
For example for my 6700K I open up 8 copies of memtest, and for my 16GB RAM I set each one for 1750 and it works out pretty good.

There's a link in the OP for downloading, I believe.

Hi there

I just build my system yesterday.

Can someone provide a guide on how to get 4.5 - 4.6 Ghz ? I am still kind new to this BIOS, after coming from a X58 i7 930 system, but will be doing some exploring in the BIOS

My specs:

i7 6700K batch L606F380
Asus Z170 Pro Gaming
Kingston HyperX Fury 16GB (2 x 8GB) DDR4 2400MHz
Corsair H110 CPU cooler
EVGA G2 1000W
Asus 980Ti Strix
Fractal Design Define R5 Mid Tower Case


Should I be following one of these guides ?

Best chip I ever got was a 3770k@4.5ghz/1.19vcore, but that was for someone else.

I bought this from microcenter, so I have the option to exchange, I just hate doing it, but bad chips always seem to give me lots of trouble years down the road when I have to up the vcore more and more to keep the overclock completely stable. I'm also worried I won't be able to use an air cooler without getting a decent chip.
What is your batch number?

Wow Vcore jumps from 1.35 to 1.408 is this normal?
This is 50 runs of x264 16t normal max temps is 82c, should I lower multi or keep going?
