Undervolt not working on Dell XPS 7590 #138

Open BRA1L0R opened 3 years ago

BRA1L0R commented 3 years ago

Yet another dell xps issue,

the XPS 15 7590 has been added to the support list in the latest commit but undervolt doesn't seem to be working on my machine. I tried both 1.5.1 and the latest bios (1.8.1).

same issue here XPS 7590

sudo python undervolt.py --core -150                                                                
WARNING:root:You have supplied different offsets for Core and Cache. The smaller of the two (or none if you only supplied one) will be applied to both planes.
ERROR:root:Failed to apply core: set -150.390625, read 0.0

It may have something to do with msr.allow_writes=on kernel option (have to validate)

Having the same issue on Linux Mint 20.1. Command and results:

sudo undervolt --core -100 --cache -100
ERROR:root:Failed to apply core: set -99.609375, read 0.0

Willing to help with diagnostics and testing if you need anything.

Fixed this by resetting BIOS to factory defaults, per this issue:
