Bonjour,

Je viens de remplacer ma carte RTX2070 S par une RX7800 xt.

Problème après l'installation et la mise à jour des pilotes graphiques, le processeur un Rysen 3900xt monte en température environ 85°c sans utilisation et 95°c dès l'ouverture d'une simple page internet et se bride a 500Mhz..

Tout rentre dans l'ordre lorsque je remet l'ancienne RTX2070S

Quelqu'un a pu résoudre ce problème ? 

Voici ma config:

ASUS ROG Strix X570-E

AMD Ryzen 3900 xt

Corsaire Vengeance LPX 2x16GB 3200MHz DDR4

MSI MAG CoreLiquid 240R

Alim 750Watts

Windows 10

Hello,

I have just replaced my RTX2070 S card with an RX7800 xt.

The problem is that after installing and updating the graphics drivers, the processor, a Rysen 3900xt, runs at around 85°C when not in use and 95°C as soon as I open a simple web page, and it clamps down at 500 MHz.

Everything went back to normal when I put the old RTX2070S back in.

Has anyone been able to solve this problem?

Here is my configuration:

ASUS ROG Strix X570-E

AMD Ryzen 3900 xt

Corsaire Vengeance LPX 2x16GB 3200MHz DDR4

MSI MAG CoreLiquid 240R

750Watt power supply

Windows 10

The issue you're experiencing with your AMD Ryzen 3900XT running at high temperatures and low clock speeds after installing an RX 7800 XT graphics card could be related to various factors, including driver conflicts, GPU heat affecting the CPU, or a power supply issue.
Completely uninstall your current AMD graphics drivers using the AMD Cleanup Utility or DDU (Display Driver Uninstaller). This ensures there are no remnants of the old NVIDIA drivers.
Download and install the latest AMD graphics drivers for your RX 7800 XT from the official AMD website.
Also Verify that the RX 7800 XT is correctly seated in the PCIe slot.
Check the GPU cooler for any obstructions or dust buildup that might be affecting cooling efficiency.
Ensure good airflow inside your case, as proper ventilation can significantly impact GPU and CPU temperatures.
