Settings in BIOS to make CPU work at high constant frequency

[artsiom82]

Hello.

I have Supermicro X13SAE wit Intel® W680 chipset and i9-14900k. I found settings to force CPU works on high constant frequency (5,7 Ghz).

I bought a new one Supermicro X14SAE-F with Intel® W880. I make similiar settings and the frequency fluctuates a lot.  I talk with support of Supermicro and they said 

" Our R&D said it's a normal behavior on X14SAE. 

BIOS have no settings to fix at 5.2GHz. And the CPU turbo boost function is normal on X14SAE."

But when I make power plan "high performance" E cores fix and works only on 4.6 Ghz, no fluctuation. But P cores have big fluctuation like power plan "high performance" doesn't affect at all. Is there any solution?

If supermicro says they have no such settings in THEIR bios, then that answers the BIOS question.

They also said :

"Our R&D followed intel's SPEC. For now, it cannot fix at turbo frequency. Maybe newer intel micro code in furture will change the behavior."  They mean that it is becaus of Intel microcode...

You need to better understand what Turbo boost/mode is.  Read these:

If you have something to say, say it, otherwise don't spam. Thanks.

I gave you the documents to read.  You dids not understand them.  What do you want me to do?

Turbo boost is automatic depending on your workload.  You cannot set it, period.

Dude, stop speaking for others, whether anyone understood it or not. I realized one thing: your knowledge is only good enough to post links. As for the topic, everything worked out.

Power plan "high performance" is simply way to fry you processor (especially i9(7) 13-14th gen).  Only if you use PC as some type of specific embedded system,  SDR platform or similar... high power plan (MAYBE) make sense , but windows isn't real time system + modern cpu's extremly fast increase clock(turbo boost...) -> latency is very small -> so you don't have any reason for "high" option in power plan. It is similar you hold the gas pedal to full while you wait at the traffic light
