HP Pavilion x360 14" Convertible - CPU Throttling

[Saa1977]

Hi

I'm experiencing significant CPU throttling on my new 14" HP Pavilion x360.  It has a MX250 GPU with 16GB ram and a Core i7 10th gen CPU.

I've run the HeavyLoad stress test, and for the first minute or so everything seems to be running fine.  At around the 1 minute mark, the CPU clock speed drops to about 0.8GHz, and tends to remain there.  I monitored CPU and GPU temperatures, and they seem ok (HWiNFO64 shows CPU max = 73degC and the MX250 max = 65degC).  The rotating 3D cube on HeavyLoad appears to stutter quite a bit once the CPU has been throttled.

I've also tested Minecraft and it's almost unplayable as soon as the CPU throttling kicks in.  It's extremely choppy as the FPS bounces around from about 80 to less than 10.

Is there any solution to this?  All drivers have been updated with the latest, along with the BIOS (F.06 Rev A).  I've tried  different power management settings, including lowering the maximum CPU performance to 90% in the hope it keeps the temperatures down so the CPU throttling doesn't kick in.  I can't find any other settings that allow you to control how/when the CPU is throttled (the BIOS doesn't seem to allow any changes).  At this point, the laptop is performing significantly worse than what I expected and if the throttling drops CPU performance by more than 50% after only a minute, then I feel I've bought a dud that doesn't meet it's advertised specification.

Any help would be much appreciated.

@Saa1977 Welcome to HP Community!

I understand that the HP Pavilion x360 14" Convertible - CPU Throttling.

HP Pc’s uses a customized BIOS setting (Tattooed BIOS) of which some features including overclocking and increasing the VRAM are locked.

This is done in the best interest of safeguarding the PC for the optimal performance and not to cause any extensive component failure.

To conclude, the VRAM on your PC is already shared with a specific value, and it's locked and cannot be changed.
