@chillhour61552 years ago I' d definitely be interested in seeing an undervoltage guide for gpus as well, i live in a very humid area and even on lower end hardware it still gets toasty, maybe a two parter, one for amd and one for nvidia. 1432
@

@gabbz1312 years ago I upgraded from a 95w cpu to this 241w 12900k and the temps are insane even on intel spec/defaults.
i went into bios and adjusted an offset of i thought that 241w would be okay as long as i dont oc, but firing up a game on stock settings and it' s spiking to 90s. Gt; _<

@redtailpilot2 years ago I' ve oc' d cpus in the past, but never undervolted. Just upgraded from 11th to 13th gen (i7-13700kf) and this is extremely helpful. Learned a lot from you! Thanks. 55
@

@Landon7832 years ago I' m glad you made an undervolting guide for 12th gen. I find undervolting is very useful for quite a few instances.
tldr: it' s great for one was my first gaming laptop was running really hot and starting to thermal throttle. Undervolting allowed it to stay cool and maintain turbo performance instead of throttling.
last time, was when my latest build kept flipping a breaker under load. Actually both my desktops have ups' s bc breakers flip and interrupt what i' m doing and cause potential data corruption.
i have to undervolt my desktop, everytime people start running heaters to keep breakers from flipping.
it' s helpful in hot weather to undervolt or turn down the power limit on your gpu in msi afterburner to keep it from pumping unnecessary heat into the room. Same applies for cpu undervolt). ...Expand 65

Did it per core and found different cores definitely had different capabilities one thing i discovered was that stability while idle was more of an issue when under volting.

@fordsrmaster2 years ago Jay, thank you so much for this guide. With you help i was able to get my 12900k system down from 425-450 watts at load, with the fans just screaming id="hidden25" ) to 300-285 watts under load. I had to take away some of the over clock ( i had to set to 5. 5ghz ) but at 5 ghz the system still is awesome. And as an added bonus the radiator fans no longer spin up to loud levels ) i' m much happier with my system now, as power consumption is an issue for me. I run my system on solar / batteries, and now the system won' t completely deplete my solar rack mount batteries overnight ) thanks again for a much needed guide. In an era where energy costs are going up daily, it was really nice to find a guide with a method to conserve some of my power. ...Expand 17

@domeleu12 years ago I played with static cpu voltage and i was very happy to see how well my 12700k responded (on a msi z690 edge) i had a huge drop in power draw and consequently then i discovered that the cinebench score was unexpectedly lower (almost half! Even if the frequencies and core utilization were maxed out during the test.
so i think that lowering statically the cpu core voltage only limits cpu performance.
on the other hand applying a negative offset adjustment gave an improvement. With a -100mv offset i saw an increase in cinebench score from about 22600 to 23175 because it reduced the cpu throttling. Unfortunately with 125mv my cpu started to become unstable. ...Expand 1

@teardowndan53642 years ago cars with catalytic converters need to alternate between rich and lean to prevent their catalytic converters from clogging up: the extra oxygen from lean phases is needed to burn off captured hydrocarbons and monoxides from rich phases.

The only time these should run rich is the first 10-30 seconds until O2 sensors reach operating temperature. .. ...Expand
