NVIDIA RTX 50 SERIES - Technical/General Discussion

Yes, after too long. Stupidly easy and dropped power usage by about 100w and at least 5C of temps. Do it. Also made the card faster in benches since I also put the core up.

bit worried here, I tried an undervolt but by mistake, I put the graph up wrong, it went really high, and when I clicked apply the pc crashed.. I managed to get into task manager after a reboot, and quit MSI AB, uninstalled it and re-installed..

is this normal? im guessing so as people that overclock and what not chase performance through "crashing" and "stability"??

Yes. It will crash if you push it too high. What card do you have?
Try 0.895v at 2, 800. Will be better than stock and around 100w less in games.
If you chase benchmarks like Steel Nomad, it needs more refining, but in games there will be, (very roughly, 4K example), only 5fps max 'native' of a difference between above and a larger, probably unstable, and defo hotter overclock.
Also, don't set the undervolt in Afterburner to load on Windows boot, then if it crashes, it will just reboot as default gpu values.
Good luck.

its the gamerock 5090.
I will look into that thank you!
yes i left to load into windows by mistake, but somehow on reboot i was able to get into task manager and quit MSI, uninstalled it and reinstalled with default values.!!

Idle temps don't matter unless it is getting hot enough for the fans to come on, that won't cause issues but will be annoying.

It's only max temps you need to worry about.

perfect, thanks!
 
TO NOTE:

I have had my side panel off all day since my setup was complete, and just before I ate, I shut the PC down and put the side panel back on, and now booted up into W11 and my temps have decreased further?

I would have assumed that the panel off would allow better airflow?? go figure!

Nope. Having the panel on will give better air flow in the direction its needed. Else the whole mechanism of air flow is interrupted. If you have the panel off and an external fan blowing into the PC you might get better temps.

well...applied the undervolt last night, came on today (granted its cold in the room atm) and my temps yesterday at "basic use" on the GPU was around 45-48c and today im averaging 38-39c! :eek:

just downloading an intensive game to test it out on. taking forever though with my ***** broadband! :mad:

Undervolting is amazing. Such a massive difference between running at 600W and 450W and the performance is pretty much the same.

and to add to that, my general usage Watts were around 85W ish.. now around 35-40W!!

That's interesting. Maybe your undervolt is affecting the lower voltage points as well then. I left points 0.800v and 0.810v alone and just selected the area between 0.810v and my chosen 0.910v. That said, I do idle the same now around 35-40W like you, with the lowest observed being 25W.

Edit: I guess you are talking about overall using less W.

Yes. That’s wattage reduced under “basic” load by about 120%!
