12900ks Pcores clock only 4.300Mhz on Cb23 with 241w pl1/pl2 Asus Rog Strix B760-F

Hello new 12900Ks with B760 Strix F, Default intel Settings (Performance) when Run Cinebech 23 Pcores Max at 4,300/4400 Mhz with 78c max temperature and 241W Package Power, its that normal behavior for 12900ks ?

You're hitting Power Throttle. It's shown on you screenshot as well. And 12900ks is locked at 241W by default. With locked chipset you cannot change it.
You multithreading score is more or less where it should be ~27.5K.

The peek Voltage you get for CPU is rather high as well 1.499. Microcode could limit voltage at 1.550, so that could also cause throttle to prevent CPU degradation.
I'm not sure if the microcode patch was also applied to 12gen CPU though.

Did you try Extreme profile or something like that?

Hello its weird cause with intel default (performance) i have seen video that's cpu 12900ks hit in cinebech 27500+ and Pcores clocks at least 4900 Mhz but with this cpu barely hits 26000 on CB23 with low clocks, im not use any ASUS MultiCore Enhancement or asus oc profile in this screenshot, vcore in Hwinfo64 when at full load its 1.300-1.307v ,i can enable MCE in this Board and this remove all limits but when test in Cinebech 23 package power hit 320-330w with Vcore at 1.42-1.41v and clock on Pcores 5000Mhz its not safe.... im wonder if my 12900ks its very bad bin or id don't know...

Most reviews and published benchmarks used unlocked profiles which were defaults profiles with unlimited power, current and turbo time even a few months ago.

The Intel Base Profiles are new thing to keep processor in power, current and voltage constraints.

When you reach power limit (or any other limit like current) it will throttle down CPU clock to keep it working with in said constraints.

But default these processors (even K series) are not meant to keep drawing max power at all times, meaning that when all cores are active, at full clock and 100% usage.

I believe those can be only achieved on unlocked CPUs and boards and tweaked BIOS settings like Asus OC profile, which will pump enough power to keep processor at max clock even when all cores active and at 100% usage, which might be outside of Intel Base/CPU specification.

Otherwise it will throttle.

Its not normal clock speeds for 12900ks 4,3/4,4 Mhz on Pcores with 241w pl1/pl2 in Cb23 something its just simple wrong and don't thing its So bad bin of 12900ks, something wrong with implement of Intel Default Settings (Performance) or CEP on this board... im not use the intel default Baseline profile ..

I hope Asus take care of this issue with this fail implemented of Intel Default settings (performance) cause this settings its the main sets after reset/default of the bios and for sure not work properly with 12900KS, also the bclk work at 98,8/98,7 Mhz all time they should add option in bios with Vrm Spread spectrum or option for bclk select or fix to 100 Mhz or just they need to fix it, all this on Asus Rog Strix B760-F Gaming WIFI Board, really disappointed..

I'm also on 12th gen (back) with B760 (-F). My cpu is locked at 4.4 GHz under 100 watt and stays cold under 60 degree. P1/P2 is limit to 150 Watt by default. I'm using the intel default profil. Didn't saw boost higher. Dunno if it's normal..

Definitely hitting some limit there. I'm on Z690-i board and a 12900KF, i'm running R23 5,0/4,1 all-core load. 1,350v/1,408v. PL1/PL2 241/280W. 300A (just so not hitting limits). IA VR-Limit of 1500. 100% stable system. R23 29K+. 5,0 Synced + 4,1 synced with added TVB+2. AVX2 Offset 3.The only issue i have is in single core tests, the e-cores drop to 3,9Ghz for unknown reasons. Have tried everything, nothing changes that. Not sure what ASUS did with the 4001 BIOS that causes that.
