Nvidia 4090 - Power limit / undervolt / both? Coil whine issue

[Asryan]

Hi,

We've seen in number of articles that reducing the power limit on a 4090, even to 60% does not decrease the performances that much.

On my GPU here's what i did :

80% power limit
Undervolt : 2700mhz @ 0,950mv

All is running fine and i've noticed no loss in FPS.

I was wondering if it's the best way to do and if limiting power + undervolt might be redundant for instance.

Also i expected to fix my coil whine issue which is pretty heavy and even worse when using DLSS3 frame generator (i don't have to use it, I know, even with it all is maxed out but still)
https://www.youtube.com/shorts/J0kfjvtOMXA you can hear in the middle of the video when it's activated, it's quite awful

I've asked the reseller if I can get an exchange they told me yes but I have to send back the card first since they have no stock but that does not help a lot since i work from home and I have a KF CPU.

Any insights?

Thanks

Just undervolt seems to work best and gives better results (lower power draw, better performance). I'm running 2700mhz @ 0.95v too, didn't touch the power limit slider.

Yes power limit and undervolting is kinda redundant.

It will whine, no matter what. I run my 3080 Ti @850 mV and it still whines at high load. Don't bother with replacing it.

isn't that whine really bad? when i use the frame generation it's even worse even if the fps are not really higher actually

Just undervolt seems to work best and gives better results (lower power draw, better performance). I'm running 2700mhz @ 0.95v too, didn't touch the power limit slider.

Ah and what about the wattage max you got? I read different things about all this

you can't do much against it.
plug your PC directly into a outlet (no splitters or power strips)
use seperate cables for PCIe Power (on different rails if you have a multirail PSU)
and what you already did, lower the VCore. that's all you can do.

I'll check in Forza Horizon 5 and New World if the Geforce Experience overlay will work, on the wall it's around 80-90W less at 950mv than default at 1050mv. I think it was around 280W when i checked in HWinfo for FH5 though.

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.
Thanks

I just installed the MSI Trio last night, I can tell you it still has some whine. Maybe not as bad as yours ( haven't heard ) and definitely much worse in synthetic benchmarks rather than in game. From what I've been reading these cards almost all have whine.
