Has anyone successfully undervolted a 920 with an 8550U? I've managed to get it running stable at -110mv without BSOD'ing under super heavy loads. When the computer goes to sleep it kicks a reboot of the machine though. Temperature and power saving are tremendous with a -110mv undervolt, so I'd like to figure out how to keep it. I should add that even a -5mv undervolt forces a reboot upon sleep.
Solved! Go to Solution.

how are you able to change the voltage? what program are you using? bios doesn't have any of that setting
also, are you getting any whea error 17 in your windows log? i am tearing my hairs out not knowing what else to do beside returning both. i am wondering if it's because i updated both the bios and the ME to whatever latest ver that is posted by lenovo. or is it because i installed win10 from scratch?

Thanks for the answer about the whea error. one more question: did you upgrade both the bios as well as the MEI firmware on your laptop to the lastest one provided on lenovo site? I have a suspicious feeling that the MEI firmware upgrade could be causing my trouble but it's just a suspicion.
Or are you still on the default bios and MEI firmware that came with it originally?
