Undervolting +power limit on 4090

[Elric82]

Hi

I'm trying to reduce the coil whine of my gpu

I managed to do it a but with

80% power limit
0,950mv @2700mhz
+1000 memory

Is it OK to lower power limit and undervolt at the same time? Running fine so far but I was still wondering.

Thanks

Yeah it's fine. I effectively did that on my 3090 and no problems

Basically whatever you're doing, if it's not crashing and temps are fine, no worries.

Hi
someone I know who does not care about noise offers me to trade my tuf against a msi trio x
Would it be a fair trade?

My Tuf is noisy for coil whine but has amazing temperatures and fans are dead silent.

I don't want to regret the change; coil whine is bad but perf and temps are great so..
Here's the coil whine of my card :

you can hear it's even worse when nvidia frame generator is enabled at the end of the video.
Thanks

I would keep the TUF personally, it's one of the best.

I've had the Trio, and whilst there is nothing wrong with it per se, it was the worst 4090 card I've personally tried.

The card is limited to 450W and only comes with a 3-pin adapter. You might be able to flash a BIOS to the Trio which would allow for a higher power limit, but then you'd have to buy a 4-pin adapter separately as one is not included.

The Trio does not have a vapour chamber, so the temps were higher than the other 4090 cards I tried for core, memory and hotspot temps. Oh and MSI RGBs software would not work for me at the time on Windows 10 or 11, so the RGB could not be controlled. OpenRGB wouldn't work as you need to run the MSI software once for it to work. This issue may be fixed by now, this was a couple of months back.

Oh well I guess i'll wait for a better solution but i was worried about this weird coil whine at the end of the video.

It's fairly normal coil whine. What were you doing at the time?

It might get better over time. Or it might hang around like an unwanted turd.

Even at the end of the vidéo? It was on miles morales spiderman when enabling dlss frame generation

High FPS will make coil whine sound worse (louder). There really no reason to use FG with a 4090, better keeping it off IMO.

Also, reducing GPU voltage will help reduce coil whine noise. You can do this by lowering the power limit of the GPU and or limiting in game FPS - if the coil whine really bothers you.

I've already undervolted but what worried me was the weird uneven noise

Well on a scale of 0 to 100 for coil whine, thats a 1 to me, actually its normal almost, guess im a lot less picky than you.
