All core Turbo Overlocking on a 12700KF using Throttlestop

[solarmystic]

I've a 12th gen i7-12700KF that i've just upgraded to on a rather decent B660M motherboard (it had a 12400F previously and i got the 12700KF for cheap, sealed).

I was wondering whether i can do all core turbo overclocking using Throttlestop since it seems to be unlocked and unlimited in the software?

Would TS be able to overwrite the B660M limitations when it comes to any form of overclocking? Undervolting works perfect and is properly applied by the software and the system. Changing PL1 and PL2 limits also works as expected.

B660 is overclocked locked. Other way around is to adjust the BLCK.

@solarmystic
ThrottleStop reports that your K series CPU supports Unlimited overclocking which is correct. I believe the Intel B660 chipset does not support any overclocking so you will not be able to take advantage of your unlocked CPU.

It never hurts to try though. Set all of the turbo ratios in the FIVR window to 50 for each Group, crank up the PL1 and PL2 power limits sky high and then run something simple like Cinebench to load the CPU. I think the chipset will limit you to the 47 multiplier. If you can run the 50 multiplier then you have just discovered a new use for ThrottleStop. You might also need to check the Speed Shift box in the TPL window and set that to the maximum suggested value. Check the Speed Shift box and press Apply if you cannot see the Min and Max values.

Post a screenshot of ThrottleStop with Limit Reasons open when doing your Cinebench testing.

With many other earlier CPUs, you had to undervolt both the CPU core and the cache. Not sure if this is necessary with your 12700KF. Does undervolting just the core work? Can you see a difference in temperatures or some other way to confirm that this is working? I know when I am undervolting my 10850K, adjusting only the core setting in ThrottleStop is good enough. The difference in temperatures when running Cinebench is obvious.

Undervolting just the core of my 12700KF produces the desired power and temperature reduction, so i presume it works perfectly.

Good to know.

Did you try the overclock test yet?

It is as you said in your previous post, the chipset limited it to 4.7 GHz all core unfortunately.

I'll have to make do with stock performance at lower temperatures and power consumption i guess, thanks again @unclewebb !
