Hi Everyone and happy new year.
I hope i might find some answers to a strange issue i have. I have noticed when i try to update the BIOS to the latest 4 versions i all of a sudden seem unable to maintain a fixed clock speed. Even though all bios settings are disabled that should result in a fixed clock speed it ramps down to base speed of 3500mhz and not the multiplyer 56 that is set. I am using MSI Carbon WIFI z790 mb with 14700kf. I can run fixed clock speed with BIOS v1D, anything newer than this with microcode 0x12b and newer and the cpu will not maintain a fixed speed. I have done everything i would usually do in the past to maintain fixed clock speeds including all windows settings for power management as well as all power management settings in bios, yet cpu refuses to run at fixed speed on newer bioses.
I very much hope to find answers that MSI refused to look for because they couldn’t repeat my issue. Intel have also been absolutely no help. I have tried raising support tickets with both. Alas, no joy finding answers to this issue, which i am sure other people have also reported on other forums.
My personal thoughts are that it could well be something to do with microcode changes, or some weird bug within newer bioses. Of course i could be wrong.

I can’t help but wonder, and if I had knowledge of machine code I would check myself, if there is a possibility that it would be a case of looking at the code to see what is causing this issue within the bios.
I have tried to look myself and got as far as using uefitool to look at the modules. However, that’s as far as I have progressed, and have no idea how to open the modules or even what I would be looking for or at.
This is a clean install because i have been hit by the cpu degradation issue 5 cpu’s in a row, all faulty all causing bsod’s from day one of delivery of them, and all running the latest microcode 0x12f. This is why this is a problem, BECAUSE i am fully aware of the issue and the need to run the latest microcode. However, having already said that i am running a fixed cpu clock speed, i know i need, for safety, to run the latest microcode. Unfortunately. there is some kind of strange issue with microcode 0x12b and newer that prevents me from running a fixed cpu clock! MSI claim to be unable to repeat the issue i am experiencing. But it cannot be anything else aside from a bios/microcode issue causing this because i am running a fixed clock on microcode 0x129, but cannot on any newer bios/microcode than this. I can see that your English is not very good, so let me know if you cannot comprehend what i have said!
So. As anyone can see. This has been debugged already, by running a completely fresh install of Windows 11 25h2. Furthermore, i am fully aware that assembled code functions is not for me, that is why i’m asking a community that does know assembled code for assistance.

Thanks for doing so @Fernando. I admit it was definately not constructive to this issue.
