In keeping with an in-depth evaluation by an overclocking knowledgeable, the overheating concern that has been plaguing some AMD Radeon RX 7900 XTX graphics playing cards appears to be affected by the orientation of the cardboard throughout the laptop.
Standard overclocking knowledgeable Roman Hartung shared a video on his YouTube channel, der8auer, that delves into this thermal throttling concern, and he discovered some attention-grabbing outcomes. If the RX 7900 XTX is put in with a vertical orientation, the graphics card appears to run 10 levels to fifteen levels Celsius cooler than the identical card laid horizontally.
Whereas mounting vertically may present a little bit of reduction to homeowners of AMD’s Radeon RX 7900 XTX, Hartung mentioned that throttling nonetheless occurred no matter how the cardboard is put in. This led to additional experiments to attempt to establish what the issue is in hopes of fixing it rapidly, with out a have to return the cardboard to AMD.
One other check was executed with the cardboard mounted horizontally however the other way up to examine if gravity was pulling the cooler away from the GPU, probably lowering its effectiveness. There was no change within the outcomes and the RX 7900 XTX nonetheless received sizzling and throttled after a couple of minutes of heavy use. Hartung dove deep into a couple of different cooling particulars that additionally proved fruitless.
I used to be Improper – AMD is in BIG Bother
The idea that continues to be, if true, is extra problematic: that there may be a defect within the vapor chamber used with the AMD Radeon RX 7900 XTX. Vapor chambers, also called warmth pipes, benefit from the section change of water boiling to turn into vapor earlier than condensing to chill. When working correctly, a vapor chamber quickly transfers warmth away from high-performance electronics.
Hartung’s checks had been carried out on 4 AMD RX 7900 XTX reference playing cards, to permit for some variance. Bigger samples end in higher outcomes and scientists rely on a whole bunch or hundreds of samples. Finally, AMD might be in one of the best place to establish and proper the overheating and ensuing throttling concern.
The corporate has already formally responded to the complaints, however we’ll must see if an official recall is within the works. Overheating points have been an ongoing drawback with the newest technology of high-powered GPUs, beginning with the Nvidia RTX 4090’s melting cables.
Following the information, AMD shared the next assertion with Digital Tendencies:
“We’re working to find out the basis explanation for the sudden throttling skilled by some whereas utilizing the AMD Radeon RX 7900 XTX graphics playing cards made by AMD. Based mostly on our observations to-date, we consider the problem pertains to the thermal answer used within the AMD reference design and seems to be current in a restricted variety of the playing cards offered. We’re dedicated to fixing this concern for impacted playing cards. Clients experiencing this sudden throttling ought to contact AMD Help.”
