11900k Power Throttling to 3.7 gHz

Hey all

 

I'm running an HP Omen System (yuck I know) with the specs (see screenshot also):

Motherboard: HP 886c

CPU: i9 11900k

GPU: 3080 (10gb, apparently intel xtu has a bug which causes it to display the 4gb falsely)

 

When running cinebench I noticed (see screenshot) that there was constant Power Limit Throttling, aswell as occasional Current/EDP Limit Throttling and Vmax stress throttling (though the latter 2 are constantly on only during idle for some reason? not during the benchmark).

Just looking for some troubleshooting points, I already saw the following somewhere: "Reasons might be numerous but most common would be power limit enabled in BIOS. The other common would be connecting only 4-pin EPS cable to motherboard instead of 8-pin." I can see if I can check the latter, but sadly the kind manufacturer HP Omen has their own bios, in which I can't accessed the advanced tab and according to a support topic on their website this is probably impossible to unlock (thank you hp!).

 

Could it be possible also the power supply is bad? I think its an 800W ATX gold but i am not sure since the product has disappeared from their website (thank you hp!).

 

Looking to build my own with a new motherboard anyway, but I want to see if I can fix this first.

 

any ideas greatly appreciated!

side note: I did all this because I was getting down to 90/100 fps in cs2 which seems insanely bad for a 3080 and 11900k combo, and couldnt identify any bottlenecks with hwinfo other than that the first few cpu cores were pretty high usage (around almost 95-100%)

It isn't a bug as such as a mobo "feature". Does XTU let you raise the power limit? I've used that trick before on a mobo that didn't give options. It might even be the mobo can't sustain higher powers for a long time so they enforce that limit.

Main system: i9-7980XE, Asus X299 TUF mark 2, Noctua D15, Corsair Vengeance Pro 3200 3x 16GB 2R, RTX 3070, NZXT E850, GameMax Abyss, Samsung 980 Pro 2TB, Acer Predator XB241YU 24" 1440p 144Hz G-Sync + HP LP2475w 24" 1200p 60Hz wide gamut
Gaming laptop: Lenovo Legion 5, 5800H, RTX 3070, Kingston DDR4 3200C22 2x16GB 2Rx8, Kingston Fury Renegade 1TB + Crucial P1 1TB SSD, 165 Hz IPS 1080p G-Sync Compatible

Thank you for your answer!

 

The feature sadly basically doesnt let me do anything in my own bios which is insane to me..

 

You're right it lets me raise the power limit for Intels Turbo Boost Technology, which I have enbabled. It says the default is 175, with an active of only 125, and also "Proposed: 125". I found info on the motherboard and it says "TDP: up to 125W" So it seems you're right.

 

Would it be safe to raise it? Or should I get a new motherboard first? And why would they use a motherboard that doesnt have enough power for the 11900k...

 

Other side note: The mobo lists 11900k as a possible cpu, listing the 11900k's TDP as 65W. But intel lists it as 125W. So there's that

Unfortunately common in OEM systems.

The TDP is the nominal long term power draw than Intel defines, and is the minimum expectation for support from a mobo. Short term boosts above that are expected and allowed. It's mainly overclocking tier enthusiast boards with more beefy power delivery where sustaining above that indefinitely is expected. Note Intel don't view power limit adjustment as overclocking. The mobo should protect itself if power draw is sustained beyond its comfort zone.

 

You could try to estimate how much power delivery that mobo has, and compare it to others. Look at the number of power phases as a starting point.

Probably a typo. 11900 is 65W TDP, 11900k is 125W TDP.
