Dells RTX 3090 Are you Undervolting?

I can't remember out of my head, but I think the voltage slider is locked out on these cards.

I lowered the power limit of the card to obtain lower temps without dropping too much performance.

Gotcha , so you just lowered the power limit in AWCC / Gpu. Do you remember how low ? Maybe somewhere around 10% - 90 on the slider.

Down to 65%.

There was a YouTuber that bought an R11 w/ the 3090 the same time I got mine and I notice that his 3090s frequency out the box was like 2040 MHz and he said he didn’t do anything to get it that high. His temps was the same as mine underload which is a comfortable 72-75c. I have always wanted to get a slighter higher frequency on my 3090 so that’s why I’m interested in maybe trying to undervolt with alittle bump in the core memory clocks. Mine is usually around 1905 a 1935 MHz which is really not bad. 

Wow 65% !  Gotcha thx. 

You should be able to run the card 1920 @.925mv using afterburner and get excellent performance while lowering temps.

Just a suggestion…

Voltage on OEM card is locked and not adjustable.

I have been running my Dell RTX3090 at 0.800mv (MAX.Voltage) for 2 years now, in my Alienware R11. I did this to cut down on thermal throttling caused by the VRAM getting hot. I found that on my 3090, 0.800mv was the lowest stable voltage I could go.

*M/J = Memory Junction

*H/S = Hot Spot

(* I had to rename them in my monitoring app for unrelated reasons.)

The screen cap is after playing Cyberpunk 2077 @ 3440 x 1440 resolution with HDR enabled for a few hours. You can see that I had a full load on the core. Just so you know I am not trying to play it off as if I had low voltage, but there was no load on the GPU.

I was running at stock clocks in the image, but I did run it for a long time @ 1830MHz on the core. I stopped running that clock recently, due to heat generated while playing more graphic intense games. I stay away from over clocking the memory because it just added more heat. The temps are still higher than I would like on the Memory Junction, but I am fixing that tomorrow by repasting the GPU and the VRAM Heatsink. I am going to replace the thermal pads as well. Hopefully, after this I can overclock it more without the throttling.

I use Afterburner to overclock and to setup a voltage curve, so the max does not go above 0.800mv. 

Yeah, After-Burner (and knowing how to use it) is the key. I don't OC (or run at high power-limits) , but my RTX-3080 runs awesome with it.

If something is going on with After-Burner dev lately, I see Zotac is bundling/suggesting FireStorm instead.

It's interesting. Afterburner development has halted for now, and EVGA has stepped out of the video card business so XOC is not going to receive development either.

So that does not leave the video card community with a lot of options.

At least Rivatuner is still being actively supported and developed.
