Hi! im kinda new in the pc world and i discovered all this about undervolt!
I want do it to my Amd Ryzen 7 3800x and to my GTX 1060... but firts i wanted to know more or less the problems what i maybe encounter! so im prepared!
Thanks for all your help
Edit: thanks for all your advices,was gold for me,i really appreciate the help
It's not really an undervolt that your looking for, but a voltage offset. It means that you'll give less volts then the CPU basicly requests. Can be anythin from -0.10mv up to -0.350mv. You have to test in order to know which offset works best for you.
My older 2700x would allow a offset of almost 100 milivolts. Because of that it was capable of staying under the 60 degree mark and hang as long as possible at 4.2GHz at all cores.ID: h52bdzt
I see! thanks you 🙂
people here say to set the PPT down to 48 in ryzen masterID: h519hyy
Like so much stated already. Just stay stock. It's a lot of hassle to mess with r7 3800x. I have one and got no performance worth mentioning. Pbo worked alright but wasn't worth the extra heat. My cpu became quite unstable with even the slightest bit of an undervolt.
You will have much better luck messing with the gpu. At least cutting the heat back.ID: h519lg7
I will keep the stock configs,thanks a lot for help meID: h51jnr1
Yer welcome. And I have my cpu at stock, without pbo enabled. Make sure to use the and powerplans and not the windows ones. Those are installed with the and chipset drivers.
My 3800xt does not like undervolt, not even a little bit. Its performance drops with any undervolt.ID: h514kiw
Oh! thanks for the info
you could just use eco mode, basically become a 3700x, maybe with more headroom.
depending on what you do, i doubt you'd notice any difference with the 1060ID: h519k1r
Then i will try the eco mode! thanks a lot
I got some small gains (well, was a tiny amount of effort) setting max boost clock at 175mhz and negative 5 offset on curve optimiser. Free performance for 1 minutes effort.
No, you can't really tune Zen2 chips much. Either leave them stock or simply switch on PBO for a tiny bit more performance (but also higher temperatures).
Either way the most you're probably going to lose out on is 1-3% in performance (stock vs overclocked). Don't lose any sleep about it.ID: h514jwi
Thanks for the advice!ID: h51fmn8
Undervolting my 3800X by -0.075v dropped my temps 10C and wattage by 30w
Performance went down 1%
30W savings for 1%? Good deal.
