Predator Helios 300 PH315-53 (2020 Model) BIOS Backward Compatibility and Overclock Fix.

invador0007

Friend of mine was suffering thermal throttling due to factory overclock of (+50mv) followed by BIOS update 1.07 on Predator PH315-53 (2020) and decided to risk backward BIOS compatibility by flash previous BIOS 1.06 and good thing is it's backward compatible. For those who are having locked out ThrottleStop and Intel XTU, can flash older BIOS to restore and fix thermal issues as well.

For the proof, posting photographs below and if you still don't want to risk, it's all up to you after all that is your laptop and money.


As you can see now the clock speed are unlocked.


Hope it helped, sorry for the image quality and if you are still skeptical about it then don't flash.

Download BIOS 1.06 zip from support page and extract the zip then run exe while plugged into AC adapter further it'll do it by itself.

note: after flashing BIOS it'll take several or two restarts to boot OS, don't panic or force restart/shutdown.

When I do that I get this error..

To bypass version popup.
Just download and execute the "H2OFFT-Wx64.exe" in the zip.
Google Drive - link
This zip is strictly for PH315-53(Intel i7 10750H and RTX 2060) model.

The file you gave me worked perfectly, and when it was done the overvolt was gone and undervolting was open.
but when I restart the system starts updating to 1.07 automatically. I dont know how to stop it.
tried it twice now and it updated automatically twice too.

Update: was able to fix this by going to Device Maneger > Firmware > Proprties > Roll Back and picked 1.06

I still had to use the provided file that our friend provied and I really don't know how to thank him enough.

Thank you buddy looks like its working now.

Fix this by going to Device Manager > Firmware > Properties > Roll Back then select 1.06.

To access voltage offset "Unlock Variable Voltage" should be ticked then it'll be available.(incase you forgot to tick that box)

Oh boy this thread helped me to revert back to 1.06 and I didn't have to do the roll back from device manager

Thanks to the op for this

@AZZIZ You also have the option to permanently disable the firmware driver:

Windows update will not update the driver firmware.
