10850K Overclock

[baris_]

So I got my new rig and,

I'm kind of confused about the overclocking of these 10th gen chips. With the turbo boost (the added wattage PL1/PL2 etc.), the fact that the motherboards already run a lot of voltage on them. I mean, I only overclocked three chips, Q9550 and i7-7700k and i3-8350K. I don't think I ever put more than 1.28v in any of them and at stock (auto) this i9 blasts ~1.39v (~80C average) on all cores after 5 minutes of small FFT's. It feels rather unsafe to even leave it on auto.. Do these chips just run on higher voltages and is, say 1.4v safe long term? Mind you, I'm on air cooling (albeit good air cooling).

Also, it's advertized as 5.2 max turbo, but during the FFT's and all the other testing (like 3dmark) it never went beyond 4.9 except for one core hitting 5.0. What gives?

Seems to me like the stock settings are just **** and we're meant to tweak this chip. Whether that is undervolting and finding a decent stable clock or overclocking with an as low as possible voltage.

I also wonder how accurate the readings of the voltages are in HWMonitor.

Hope you lot can share some thoughts on this!

Regards,

Baris

To check single core performance try cinebench R15 single threaded. Here is an explainer of all of the different boosting algorithms, to hit max boost you have to be under 70c. https://www.tomshardware.com/features/intel-thermal-velocity-boost-glossary-definition-tvb

Thanks! Loud and clear. I could probably already get lower temps by just not leaving the vcore on auto but manually putting in lower constant voltages because obviously with 1.35-1.4v the temps are never gonna be below 70c, at least on air.

what did you end up lowering the vcore to? I notice mine jumps from 1.18 to 1.38 and all in between. Using NZXT Kraken x62 right now and during cenibench I hit around 77 after 1 pass and 81 after second pass and plateaus around 82. I have speeds at stock as overclocking this CPU is rather useless. OC'ing to 5.1 from 4.8ghz is barely a performance boost and isnt worth the added heat and power needed. I just want the lowest possible temps at stock. Idle i am around 30 degrees.

every CPU is different I would suggest just experiment with negative voltage offset on vcore by -0.05v or even smaller increments and test for stability with something like AIDA64. If you have further questions please start new thread including a listing of all of the components on your computer.
