#High idle VRAM clock on 5700 XT

My AMD graphics card's idle VRAM frequency runs at high speeds. Even though I’m not putting any load on the GPU or the VRAM, the frequency stays above 1700 MHz, which causes my GPU temperature to increase. Even though my graphics card has the Zero RPM feature, I have to keep the fan speed around 35–40% at idle, because when the fans stop, the temperature rises significantly. I use two monitors, and when I turn one off and run a single monitor at 60 Hz, the VRAM frequency drops. But I want to use a high refresh rate and also need to use dual monitors. With my previous cards, I used the same monitors without any issues at normal frequencies (PowerColor RX 570 4GB and ASUS GTX 1660 Super), but I encountered this problem with this model. How can I fix it? I want my card to run cooler and quieter at idle. My card model is: ASRock Challenger RX 5700 XT. I also tried creating and selecting a Custom Resolution on both monitors at the same time (using the CVT – Reduced Blanking option), but it still same. It works on a single monitor, but no matter what I do with dual monitors, the VRAM frequency keeps running at high speed.
My monitors:
MSI G255F
LG Flatron E2240S
[Driver 25.10.2]

My second monitor doesn’t support FreeSync. When I enable it only on the monitor that does support it (MSI G255F), the result is still the same.

have you ever seen lower power consumption / low VRAM clocks with multiple displays?

#

on another driver version

No, it's the same on older versions. I tested these versions: 20.4.2, 20.9.1, and 21.10.1

nothing that can be done about that, then

#

just the strain from having to run more bandwidth through the display engine

#

if you really want to lower the consumption, you could lower the refresh rate or resolution on either or both of the displays

With a single monitor it works to extend the blanking time. Sometimes with dual monitors it will downclock if second monitor is set to 60hz, thats the case for me with a 7800XT. Im running the second monitor of the iGPU though (connected to motherboard) because I want to run my second monitor at 120hz 🙂

And with the increased idle clock speed its enough to make the gpu go in and out of zero rpm mode just as yours... very annoying.
