High VRAM temperature - RTX-3090

[TIG]

I noticed Isonzo game pushes the GPU VRAM temperature to as high as 88 - 90 deg. But the GPU temperature is normal up to 68 deg.
is there any graphics parameter can be reduced to optimize GPU VRAM Temperature below 88 deg without affecting the graphics quality much.

CPU: i9, 12900K, 32GB RAM
GPU: ROG Strix RTX3090 24GB RAM
4K display
ISONZO graphics settings at all ULTRA
All drivers been updated and Nvidia Control Panel at default.

VRAM Temperature for other games at ultra is not as high as in Isonzo game.

Thanks

On 3080 and above; this is quite normal and nothing to worry about. The VRAM is going to run hotter by default when being used. Under 105*C for the VRAM is perfectly fine.

NVIDIA's recommended GPU Temp of staying below 84-90*C does not apply to the VRAM or VRMs. That only applies to the GPU Core.

Hey, I know it's been a while since you uploaded this thread, but I wanted to give you some advice!

First of all, GDDR6X memory is known for running really hot, and stock thermal pads are usually rated at 13W/mK for thermal conductivity. With that said, the only way to significantly improve VRAM temps is by replacing the thermal pads with ones rated at 16W/mK or higher.

I personally have an RTX 3080 Ti ASUS TUF, and the stock pads allowed temperatures to reach about 86 degrees Celsius at max VRAM usage. I replaced them with some 13W/mK pads, but the temperatures stayed about the same. I only noticed a big improvement when I used 16W/mK pads, which brought the temperature down to just 74 degrees Celsius under maximum usage.

If you want to improve those temps a bit via software, you can reduce the memory frequency, though this only helps slightly. Additionally, undervolting the GPU core can provide some benefit.

That said, replacing the thermal pads is the best way to achieve better temperatures. Hope this helps!

I hope OP doesn't have a heart attack when they check out how hot some of the sensors show in these things.
