I just found out about mVolt+ and decided to spend an hour testing it out on my i7 14700K+4080 Super system to some really good results and the top score in Speed Way for this config. CPU is stock and RAM is 6400CL30.
I bumped up the wattage from 320 to 375 and it used about 360W for this run. Temps with 100% fan speed stayed under 62C on the stock PNY VERTO OC cooler in a hot Southern California room with an ambient temp of 85F, so I'm excited to see better scores once Winter comes around.
DONT COPY MY SETTINGS BLINDLY. DONT BURN DOWN YOUR HOUSE.
Settings: +255 core, +1400 mem , +300 XBAR, 1.1V up from 1.075, and I capped clock range at a max of 3000MHz so it wouldn't randomly spike and cause a crash during the run since I saw clocks wouldn't go over 2940MHz anyway.
Super(pun intended) cool tool and a nice way to get some free performance. From my 7,484 stock score to 8,361 is an 11.72% increase. I plan to do some more testing beyond the hour I had and then dial back the watts and voltage for everyday gaming.
Let me know if you have any tips or tricks!
