Dell G5 or G7 or XPS series -- XTU / ThrottleStop undervolting issue (Crash)

Apparently dell did a "GREAT" job with these^^ machines' thermal performance.

I am reaching 99oC most of the time and experience thermal throttle just like how other users did. (the keyboard deck is so hot which even burnt my fingers at some point)

so I decided to undervolt the laptop and everything went better from that point...

until recently from the latest bios update, I started experiencing crashes whenever I put my laptop to sleep (it will put the laptop into a hard reboot...)

I was using XTU the whole time as I cannot install throttlestop due to the (winring0.dll) error...

below are some users experiencing the same problem:

"Previously the fix was to go into the BIOS and set 'Force S3 Sleep', however Dell in their infinite wisdom have removed this option."

So I really hope Dell can either talk to the XTU guys from intel or tweak the bios in their coming updates???

I really didn't expect to have such a bad experience with a >$1500 laptop...
