On Demand Clock Modulation Throttled when Type-C allowed in BIOS

[ALyons]

Hi all,
Recently ran into an issue where the computer started creeping. After days of troubleshooting and a reset of Windows 10, isolated it to the CPU being throttled.

Looking at HWiNFO64 it seems that said throttling is occurring through the On Demand Clock Modulation which is stuck at 43.8%. This goes back to its happy 100% if type-C settings are allowed in the BIOS. This makes me think it is on the Windows side of things as the standard Intel PowerStep throttling/sleep is working fine.

Running an intel core i7-4800MQ with windows 10. All drivers and BIOS are up to date.

As it is a laptop i'm running it in, any assistance you could give to get that clock modulation back to dynamic but not stuck at 1/2 capacity would be greatly appreciated.

Thanks,

Angus

Ok- it seems to be a speedstep rather than type C issue. I have got around it using a combination of throttlestop and PPMpanel to force full CPU usage but some throttling as well, not as efficient as Speedstep but better than nothing. Just waiting on new drivers/Win updates and hoping for the best

Hi there. Did the issue fix itself later on with new updates?

No, turns out Dell now wants you to use a 180w charger, if you use the 130w that I have used without issues for the last 2 years the system throttles the heck out of the CPU clock.
