AMD's overheating GPUs might be worse off than we thought - Digital Trends

According to an in-depth investigation by an overclocking expert, the overheating contented that has been plaguing immoderate AMD Radeon RX 7900 XTX graphics cards seems to beryllium affected by the predisposition of the paper wrong the computer.

Popular overclocking adept Roman Hartung shared a video connected his YouTube channel, der8auer, that delves into this thermal throttling issue, and helium recovered immoderate absorbing results. If the RX 7900 XTX is installed with a vertical orientation, the graphics paper seems to tally 10 degrees to 15 degrees Celsius cooler than the aforesaid paper laid horizontally.

While mounting vertically mightiness supply a spot of relief to owners of AMD’s Radeon RX 7900 XTX, Hartung said that throttling inactive happened careless of however the paper is installed. This led to further experiments to effort to place what the occupation is successful hopes of solving it quickly, without a request to instrumentality the paper to AMD.

Another trial was done with the paper mounted horizontally but upside down to cheque if gravity was pulling the cooler distant from the GPU, perchance reducing its effectiveness. There was nary alteration successful the results and the RX 7900 XTX inactive got blistery and throttled aft a fewer minutes of dense use. Hartung dove heavy into a fewer different cooling details that besides proved fruitless.

The mentation that remains, if true, is much problematic: that determination mightiness beryllium a defect successful the vapor enclosure utilized with the AMD Radeon RX 7900 XTX. Vapor chambers, besides known arsenic vigor pipes, instrumentality vantage of the signifier alteration of h2o boiling to go vapor earlier condensing to cool. When moving properly, a vapor enclosure rapidly transfers vigor distant from high-performance electronics.

Hartung’s tests were carried retired connected 4 AMD RX 7900 XTX notation cards, to let for immoderate variance. Larger samples effect successful amended results and scientists trust upon hundreds oregon thousands of samples. Ultimately, AMD volition beryllium successful the champion presumption to place and close the overheating and resulting throttling issue.

The institution has already officially responded to the complaints, but we’ll person to spot if an authoritative callback is successful the works. Overheating issues person been an ongoing occupation with the latest procreation of high-powered GPUs, starting with the Nvidia RTX 4090’s melting cables.
