Really need help with undervolting the 5800x and copying someone's settings. I hope this can also help other people who are trying to do the same but are unsure how.

Need help undervolting the 5800x. getting 90 degrees in cinebench r20 and r23 this normal?

I have the corsair h115i pro xt 280mm and a 4000D airflow case. Haven't changed anything from stock configurations. multiple people have reported Cinebench fetching 90 degrees so i doubt it's just me i just need to set up a good undervolt.

I'm quite new to pcs this is my first build ever, can you explain how i can undervolt? I've been using ryzen master and changing the peak core voltage and the ghz from 3800 to 4200 just to see what happens. Runs both cinebench tests no higher than 70-80 degrees max. As for PBO and Bios settings i have no clue which to turn on or change, motherboard is a msi b550 tomahawk.
the rad isnt too hot. In ryzen master i have PPT, TDC and EDC all at stock so 1000, 140, 220 respectively. I have peak core voltage at 1.2 volts and running at 4.2ghz. idles at high 30s but still get 85 in cinebench r 20 and r 23
my question is should i reset ryzen master settings to stock and just work in bios?
i dont even know if i have PBO enabled what is/how do i check LOL
what does it mean when in ryzen master it shows all ppt, edc and tdc all say 100% usage when running cinebench? does this mean i have to lower their values or increase them?
im sorry but none of this makes any sense
what about setting the ghz? or do you leave it at stock or change the peak core voltage
ok so i set peak core voltage to 1.2ghz in ryzen master and set the ghz to 4600 and it runs max 75 degrees compared to 90.
it manages to run at 4600 when running cinebench, and the score is higher around low 6000 for r20
see when i boot my cpu temp is 50 degrees then a few minutes later goes down to about 38. i think im fine if i can nail a few settings
does the usages of tdp, edc, ppt and cpu power matter that much?
ok so i think i figured it out. in ryzen master it is defaulting to the highest limits for PBO and they were what i was running. why would this be the case?
almost instantly
yeah ive tried setting new limits and temps are WAY lower. why on earth are my stock pbo limits set stupidly high??
