Question Core Ultra 7 265KF doesn't reach full clock speeds under load and only pulls around 200 Watts? Is this normal?

[Stefan Braun]

I have a new PC, with an Core Ultra 7 265KF, a 1,300 Watt PSU (beQuiet! Dark Power Pro 13), a 360 mm AIO (beQuiet! Silent Loop 2) and 64 GB DDR5 RAM. All of that is seated on a MSI Z890 Tomahawk

Normally, the CPU should clock up to 5.4/5.5 GHz on the P-cores and 4.6 on the E-cores. In my UEFI, I enabled XMP and the preset that sets the PL1 to 250 Watts and PL2 to 290 Watts (or something like that, it's the 2nd tier from 4, 1st tier is Intel default).
When I stress my CPU, using either CineBench or CPU-Z, the power draw is around 200 Watts (+/- 20 Watts) and the E-cores reach their 4.6 GHz, but the P-cores don't clock higher than 5.2 GHz. Under stress, the CPU reaches up to 84 °C, but usually stays a bit cooler. 84 °C seems to be the max.

Why is it not clocking to 5.5 GHz? Sure, 0.3 GHz isn't really the word (of 0.2 GHZ if you count out Turbo Boost Max 3.0), but why is it doing that? Is it running too hot?

Stated clocks are the maximum that the cores can go when the workload is light enough for them to do so (fewer threads or lighter threads) all cores at max clocks under any condition would be overclocking, which your mobo supports so you would probably have to either select it somewhere or do it manually.
It's usually called all core enhancement or something.
