14900K Dropping Core Clock

[Matutu]

I have a issue with my 14900K, unsure if this is normal. If I have everything on Default including MCE auto and enforce limits of 254Watt P1/P2 I am having my core clocks drop from 5.7 to around 5.2 instantly in any bench mark.
However I have remove all limits I instantly get 330w approx, is this normal?
I thought the stated limit of 254 allowed for full clock speeds.
Thanks.

Whats your temps? Dropped clocks usually indicate thermal throttling.

Sounds normal. Pick between lower power (and performance) or higher power (and more performance) with all limits removed.

Sounds more like throttling due to high temps. I'm getting a higher all core clock on the 13900k with limits enforced. Read into setting the offset voltages and adjusting the load line's.

My 14900k with Intel limits set stays at 5.7 providing cooling keeps up.

Your likely thermal throttling. Run Intel XTU benchmark and it will tell you.

Not 14900 but my 14700 holds its clocks fine in benchmarks up until it hits 100C in extreme multi-thread tests when it starts to drop them unless I turn the fans up.
