Question Core clock reduced due to IA Thermal Velocity Boost- TVB off and still issue

[biggal76]

Hi, I am trying to overclock my I5 13600KF. Have an MSI Z790 motherboard. Running HWiNFO64 shows the IA Cores Clipped due to Thermal Velocity Boost error and it shows the clock speed is generally running around 4800GHz. I have it overclocked in BIOS to 5600 at 1.27V and temps only hit 81 degrees running Cinebench 2024. Speedstep, speedshift, hyperthreading is off. TVB is disabled in BIOS so I am confused. Even running MSI's Turbo mode (which MSI sets at 5200) has CPU throttling similarly and at a max core temp of 72 degrees with TVB disabled and otherwise the stock MSI settings. Any help would be appreciated.

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, used, refurbished)? History of heavy gaming use?

Disk drive(s): make, model, capacity, how full?

What is driving the requirement to overclock? What specific performance increases are expected?

I've spent days on it before posting the question, but this morning I woke up with new ideas and got a seemingly stable 5.7GHz pcores, 4.3 ecores at 1.295V runs 83 degrees on Cinebench. 60s on Iracing and 70s on Project Cars 2. I did a clean overclock starting with stock settings (not Turbo). Set clock speed, voltage, turned on BCLK 100mhz lock, turned off hyperthreading and speedstep, set fan curves, set max wattage to 181W. I think that's all I did. My failed attempts that throttled I had started with the MSI Turbo settings and tried to tweak from there.
