![]() Temps and power-draw speak for themselves and in Passmark's performance test, difference in power consumption was even more pronounced. Not entirely stable I reckon, although so far it's only been Doom that seemed to have trouble and I can't be 100% sure it's the UV/OC that caused this.Ġ.9V, 1905 MHz, 7600 MHz VRAM (+600) results. Went down by a notch to 1935 MHz and now all seems well again. With 0.95V and 1950 MHz, Benchmarks all ran fine, but Doom Eternal would occasionally crash/freeze up completely (which it hadn't done before). Only trouble I ran into was on my first attempt with 0.9V I didn't lower clock-speeds far enough and crashed both Heaven and Windows Explorer. With these settings my system was rated as "great" in Time Spy while before (even with a non undervolt, Afterburner Auto-OC) it was only ever rated as "good". I also raised VRAM-speed by 800 MHz, so that too will probably help a little with those scores. I've since upped voltage to 0.95V to be able to go a little higher on the clockspeeds and now the card performs better than stock in all the benchmarks I've tried - while still running cooler and with less power-draw. Card also never runs into power-limit now, which it always did in benchmarks both with stock and Auto-OC settings. Minus 6 to 8☌ on GPU and hotspot temps and between 25 and 45W less power-draw depending on the application. Going down to 0.9V gave me some pretty impressive power and heat savings without affecting performance in any meaningful way. Should be the same procedure for any RTX card I reckon. ![]() Here's a couple of vids that helped me figure it out:: Be methodical and it shouldn't take to long. You will want to make changes, then run the game to see if it stable noting big stutters, freezes, and crashes then move on to the next setting changes. I recommend you watch a few vids on Youtube about how to undervolt and take notes especially while setting up your cards sweet spot to track your changes. ONLY download MSI Afterburner from the MSI website to be sure you don't get any unwanted hitchhiking malware. ![]() Most of the other utilities are cumbersome and non-intuitive. There are a number of utilities and ways to accomplish undervolting, but I highly recommend MSI Afterburner - it works with everything (games that is and other software) is easy to use and it's free. ![]() ![]() There is a period of trial and error while you find the sweet spot for your card, but once it's done it is set and you can pretty much forget about it. The card was running at extremely high temps (90+ C!) in IL-2 even with fans blowing at 100% before and now I can hold temps in the mid 60's C range in IL-2 144 FPS on a 32" inch monitor and low 70's C in MSFS 2020 82 FPS, so it is definitely worth it. I undervolted my EVGA 3080 and the results were awesome. ![]()
