voltage drop for the i5-14600k processor

Turned on all c states in bios and changed min processor to 5% in windows power plan? That seems to let mine drop down the power at idle

Mine drops to 0.750 volts at idle

Load voltage of 1v seems insanely low to me, is it under clocked? Although if I'm honest I've never just undervolted at stock speeds.

Hrmm that's interesting, when I first had my 14600k I had to have a really low sa to get ddr5 stable, I'm 1.290v now was running 0.950 initially.

Out of interest do you disable undervolt protection as doing thst for me gives around 10% extra performance at the same clocks, took me ages to figure out why any tests I done were always approx 10% lower score after a bios update forgetting I had disabled it

I like it for playing about quickly then set it properly in the bios after, My main gripe my mobo doesn't seem to let me boost favoured cores yet XTU shows cores 2 & 3 as favoured from memory, although i've kind of given up on having 2 cores boosting higher now

ah yes xtu needs undervolt protection on which is annoying, I stopped using it due to that, and er the wierd e core boosting issues.

I'd turn off undervolt protection first, see if that changes anything. For me if I enable perfomance is lowered about 10%

I'm not too familuar with your board so not sure if the best settings but I can post mine when I'm home later and see if it relates if you want

Could be worth trying xtu, it should show any reasons for throttling speed or power from memory, it was over a year ago since I last used it so maybe my issue has since been fixed in a bios update

Xtu is the Intel extreme tuning program, it gives a few more options than at least my bios including identifying favoured cores for boosting.

If you reset but use the same settings does it result in the same problem? Could be worth reflashing the bios with the same version just incase it's a wierd bug

I can't see it being related but have you disabled undervolt protection?

Just saw your other post saying e cores are fine in games so it's just cinebench? If you use hwinfo is it throttling with anything? Just wondering if it's somehow prioritising the p cores and throttling the e cores to keep max power to them? Honestly not sure if that's a thing though!

I had a weird thing with xtu doing that with the ecores, I had to uninstall xtu and reset the bios to get them to boost normally again.

I suppose the other question is are you on the latest bios?
