For sure. With SKL and 1 GPU, you have massive rad space!

OK guys question, I have been playing with my PC at 2133 memory speeds, and the same 4.7ghz 1.46vcore for the last 3 days. Temps were perfect, just played overwatch for like 2 hours and never saw it go over 60c. I stopped playing, rebooted changed memory to XMP setting which went to 3333mhz. I also changed ram voltage to 1.36. booted back into windows, and my CPU temps were way higher. idle went from 30'ish to 40'ish and load went from about 70c to 90c.

any reason why memory speed / timing would have this effect?

surprisingly after benchmarking and testing, my overclock was not effected from the jump from 2133 to 3333, but temps were.

UPDATE to last post

I manually changed to 3066mhz and tighter timings of 15-15-15-35, and now my core temps are back to normal. If i load the XMP profile they skyrocket even in the bios. bios normally is 32c, w/ xmp loaded its 47c.

I noticed RAM at about 3300 & beyond, the auto voltages for VSA & VCCIO are higher. That could have contributed to the cpu temp increase.

Well! Good news! I should be joining this club most likely very soon! Either Sky Lake or Kaby Lake depending on prices and performances of Kaby... Selling some stuff getting ready for a massive upgrade...

Looking to get an ITX board, 6700k which I'll delid and CLU, and some ~3000MHz DDR4

Overall I'm looking to upgrade my system so It'll be good for the next 5-7 years...
post #8226 of 11360
Well I finally upgraded to a 6700k.

My final settings are:
4.6GHz @ 1.37v (Even 1.4v is not stable at 4.7GHz on Prime95 and temps start to skyrocket)
CPU SA: 1.25v
CPU IO: 1.2v
RAM: 1.35v (DDR4 3200 14-14-14-34)

Both SA/IO show up as red with those voltages. I also noticed after I set my ram to it's rated settings that my SA/IO voltages skyrocketed if left on AUTO, around 1.27v on both. I lowered them down to the recommended voltage, disabled turbo, but left speedstep/etc on. Not sure if I should disable that too, I usually do but I don't really want 1.37v going in tho the processor 24/7..

Firestrike Extreme only gained 400 points compared to my 3770k @ 4.5GHz. Oh well, at least I have M.2 and stuff now. rolleyes.gif

Does this all look fine?

(EDIT: Fixed timings)

Everything looks good IMO minus your ram timings lol, im just going to assume thats a missprint.


im in a similar boat. went from the 3770k to the 6700k. I actually thought I would see more of a jump, but in reality, for games I see 0 difference. I laugh now, cause ive seen youtube videos showing 3770k @4.8ghz next to a 6700k @4.8ghz showing like at times a 20-30 fps difference. Well from all the benchmarks ive run on my 1080, im lucky to see 1-2 fps difference.

your not really going to see a big difference between 4.6 and 4.7ghz, so 4.6 should be fine, specially if your mostly gaming. Stability is key. I got 4.7 stable so im gonna stay there for now, temps are in order, voltage is high at 1.45 vcore. Much higher than yours. I was able to do 4.6 at 1.3v lol. Was kinda hoping to hit 4.8 and call it a day, but oh well ::shrugs::

like you said, i have newer nics, my first n.2 drive that does 2500mb right and 2000mb read biggrin.gif, and just had a fun time putting together a new build. for any of those taht dont have extra money laying about and still have a 3770k or 4770k, i suggest sticking with what you got till the gen 7 i7's come out.

heres those benchmarks i was talking


3dmark Extreme

i7 6700k 4700mhz




i7 3770k 4500mhz



Witcher 3

i7 6700k 4700mhz 63.0 fps

i7 3770k 4500mhz 82.00 fps

(EDIT: Fixed timings)

The memory timing are beautiful! Also the new Prime95 and Intel Burn test use AVX instructions which will increase temps by like 15-20C try Prime95 v26.6

Also up the CPU LLC to level 5 or 6 if you haven't already.

Heaven benchmark isn't a good benchmark to test CPU speed. It is a GPU benchmark. I saw zero improvement when I upgraded from AMD Phenom X3 8550 to Intel I5 6600K.

Hello everyone.

I have recently started to OC my 6700k, currently at 4.6Ghz @ 1.40v stable. Did try 4.7Ghz @ 1.40v, no luck tho.
Done this with the custom x264 stress test, settings: 100 loops - 16 threads - normal. (Stopped it at about 60-70 loops, 8 hours something).
Temps is just fine.

The voltages I mentioned now is the ones I set in bios. When running at 1.40v I get a vcore of 1.44v(max) and 1.42v(average)
I didnt understand some of the info about LLC stuff and so on.. Which is about the voltages and so on if I remember and understand it correctly?


I use my computer for gaming, Arma 3, WoW, Battlefield and so on..
So my question is, should I change something that might help to achieve 4.7Ghz @ 1.40v? Should I stay at 4.6Ghz and try to lower the voltage and be happy with it?
Maybe even try to get it stable with the ring at 4.6Ghz aswell and get it running at XMP?

More then one idea is good.. so keep them coming.
