Overclocking 10600K

[Tan3l6]

I have been trying to get my 10600k work at respectable frequency for a while.

Now I soom to have found stable settings, but after stressing CPU the core frequency lowers for no apparent reason. What might cause that, any ideas?

what did you change in the bios?

 

This looks like the chip is hitting a turbo time+ power limit. Id turn all of those off.

Changed from the start? LLC and voltage levels+ lotys of other stuff. Limits all should be all turned off.

Something like that

Can you list all of those changes?

Check if your hitting the power limit on your cpu. Just in case 

Try maybe Upping the voltage.

I added screenshots to my previous post. But I honestly can't remember all setting changes, as some are convenience settings, others performance settings.

that seems to be still using the stock multipler, try locking the multipler.

In my experience, the symptom of too low voltage is bluescreen, but the big frequency drop only occurs when OCCT small data set or smallFFTs with Prime 95.

This might sound stupid.

But do you have an AVX offset ( highly unlikely the reason)

Set to 0

Lock to 4,7Ghz? I tried and it does nothing different, if even behaves more erratically in response to voltage increase.

can you turn off turbo boost?

I'll try tomorrow, thanks for the help!

Maybe it's just an early adopters thing

Tried latest BIOS, wasn't able to get all-core 4,7Ghz stable, so flashed back.

Anyway it is probably going to be sorted out, as BIOS even lacks tRP timing for RAM, so the RAM can't be overclocked. Although it has tens of different RAM tinkering settings, weird MoBo but not bad.

Ah, tried still though it's late in the evening.

With Turbo boost off, all stay at core 4.1Ghz

Power tab of OCCT:

No difference of load before lowering clock:

so leave turno off, and then set a manuall multipler. What happens?

I set the multiplier manually from the beginning, 50-50-49-48-47-47 

So it's a bit odd, but the multipliers shown by HWinfo is still 4,1Ghz all core.

that seems like a turbo rations

 

what are the turbo power limits and time limits set to?

Yeah, for some reason Intel XTU thinks there's a 125W limit at boot. I think I removed all limits, anyway, heres another image of settings:

does the clock still drop?

 

What if you raise that turbo time limit?

I raised the Turbo Boost Power Max from 125W to 185,5W in XTU and now the stress test hasn't lowered the clocks yet... 7+ minutes already, maybe that was the problem.

Thanks for thinking along!
