There have been new findings regarding faulty cooling systems used in reference AMD Radeon RX 7900 XTX graphics cards. As we know, the problem was initially downplayed by the manufacturer himself, but over time, reports of disappointed users began to arrive and the matter began to be treated seriously. As youtuber der8auer has already pointed out, the reason for the high temperatures is a faulty steam chamber, which can be found in up to thousands of new Radeon RX 7900 XTX cards.
Reportedly, several hundred cards have already been handed over, including those models that were installed in ready-made computer sets. What’s more, there are even thousands of defective Radeons RX 7900 XTX on the market.
The AMD Radeon RX 7900 XTX may have a poorly designed vapor chamber. How will the manufacturer react?
Now Igor Walllossek from Igor’sLAB has revealed new important information on the case. According to e-mails received from a certain system integrator, the issue has been known for more than two weeks and is being communicated internally between AMD and distributors. As assumed, the cause of the problems is a faulty steam chamber found in several batches of graphics cards (from 4 to 6). The manufacturer is currently offering a replacement for a different model or a refund to customers. According to the source, hundreds of cards have already been handed over, including those that were installed in ready-made computer sets. What’s more, there are even thousands of defective Radeons RX 7900 XTX on the market. It is worth emphasizing, however, that the case concerns only reference systems. Original variants or references of the RX 7900 XT are free from the temperature problem.
Interestingly, another statement from AMD was supposed to appear yesterday at 18:00, but for some reason it only appeared today. It’s not very long, but at least we know that something is going on in the subject. It reads as follows: “We are working to determine the cause of the unexpected performance limitation of the AMD Radeon RX 7900 XTX graphics cards. Based on our observations so far, we believe that the issue is related to the thermal solution used in the AMD reference design and is present in a limited number of cards sold. We are working to resolve this issue for the chipsets affected customers. Customers experiencing this unexpected performance limitation should contact AMD Technical Support.”. So we have no choice but to wait for further developments.
