I just fund this thread cool. I been going around reading and getting info to undervolt my evga ge force rtx 3070 Ti ftw3 as more of a experience and see the benefits of UV. I am surprise none have help you talk about in this GPU. We all know they too busy with 3080- 4090 now to worry about anything else. If I get it going well will post to you again. there lot to read as I google. they using that MSI afterburner but going use EVGA Precision 1 see how that goes. Don't really care msi AB to use but maybe that change as far I used Precision 1 all this time not had any issue with it keeps my setting fine even after shutdown of PC. Looks you having good results Killerrrf. 

I am interested to eventually know if my EVGA 3070 is good for undervolting or not I guess I will eventually find out. there a lot to read too, So making sure i understanded well. Time will tell and really looking forward to maybe accomplish good Undervolting.
