Question i5-14500 SpeedStep not working

[PuzzledToo]

I replaced the CPU & mobo & SpeedStep is not working.

Intel i5-14500
ASRock B760M PRO RS/D4 Motherboard
G.Skill 16GB DDR4 RAM
Samsung M.2 SSD 970 EVO Plus
Windows 10 Pro

Problem is CPU is stuck at 2600 MHz

BIOS > Advanced Mode shows Processor Max Speed: 2600Mhz and Min Speed: 400Mhz.
BIOS EZ MODE it indicates Processor Speed: 4600Mhz.

Intel states the Performance-core Base Frequency is 2600Mhz. Which happens to be what I'm stuck at.

HWMonitor shows all cores stuck at 2600 Mhz.

I tried to load the CPU and the CPU fan speed went from 1100 RPM to 3100 RPM so I figured the CPU must be under some load. But the cores never went faster.

I was also expecting the cores to slow down at idle with no load, like my old CPU did.

I did contact ASRock Technical Support (not the forum). There is no SpeedStep setting in BIOS and they said it is enabled by default. They said to update the BIOS, which I did, but that made no difference. Then they said to try another CPU, which I don't have.

Before I return/exchange the CPU, is there any "hidden" BIOS setting that I should first change to see if affects SpeedStep?

Thanks foe any suggestions.

Look in windows power management.
In processor power management, Balanced power plan, advanced power settings, you want to specify minimum cpu% to be something like 20% and the maximum 100%

Problem Solved -

I installed HWINFO64 and it showed that it appeared all the clocks were working & varying with load.

I updated HWMonitor & now it shows everything working correctly. I thought it was working properly before because it showed all the cores & frequencies & temperatures & voltages & fan speeds, etc. Apparently it was not accurate though.

Sorry for any confusion.
