The reference model for the step-down Radeon RX 7900 XT appear to be fine as well. Custom Radeon RX 7900 XTX models aren’t suffering from the same issues. The issue is with the vapor chamber in that specific design. Only the reference-designed Radeon RX 7900 XTX is affected, including reference cards sold by partners like Sapphire, XFX, and so on. Which Radeon RX 7900 XTX GPUs are affected by thermal issues? This singular sensor was used to make all power-performance optimization decisions across the entire GPU. Fortunately, with AMD now acknowledging the issue, buyers of affected Radeon RX 7900 XTX cards should hopefully be able to have their GPUs replaced or refunded. Junction Temperature: Enhanced Thermal Monitoring In the past, the GPU core temperature was read by a single sensor that was placed in the vicinity of the legacy thermal diode. Ive only been able to check the gpu temperature via sensors command. Those AMD jabs against Nvidia’s melting power connectors sure feel awkward now. How can I check the GPU/Memory load and other stats I have Ubuntu 16.04 with an RX 480 with AMDGPU Pro drivers. Wallossek says thousands of cards may need to be returned, both from DIYers and system builders. On social media, more Radeon RX 7900 XTX owners than not seem to be having no thermal issues whatsoever, but Igor Wallossek’s well-connected sources claim it could affect several production batches. Cntrl + shift + o should bring up a monitor panel in the top right corner, that will show your Temps. It’s unknown how widespread the problem is. He concluded that the issues likely stemmed from an issue with the vapor chamber coolers in the reference models, a conclusion that AMD’s “issue is related to the thermal solution” seems to confirm. The tech press-especially German tech press-have been digging into the issue with noted overclocker Der8auer performing extensive tests on a reader-supplied 7900 XTX known to be affected. We haven’t covered this ordeal yet due to the holiday, but in a nutshell: Some Radeon RX 7900 XTX graphics cards are hitting excessively high temperatures. Why are Radeon RX 7900 XTX GPUs overheating? Here’s what you need to know about overheating Radeon RX 7900 XTX GPUs. Customers experiencing this unexpected limitation should contact AMD support.” We are working to resolve this issue for the affected cards. Based on our observations to date we believe the issue is related to the thermal solution used in AMD’s reference design and is occurring in a limited number of cards sold.
