Overclocking extraordinaire Roman “der8auer” Hartung has doubtlessly discovered (opens in new tab) the reason for the Radeon RX 7900 XTX graphics card’s overheating points. It will appear that AMD’s RDNA 3 flagship, one of many greatest graphics playing cards, might have a faulty vapor chamber.
Hartung bought 4 reference Radeon RX 7900 XTX graphics playing cards to get to the foundation of the issue. He found {that a} horizontal set up contributed to enhancing temperatures. The orientation yielded enchancment as much as 20 levels Celsius. However, lamentably, the graphics playing cards exhibited the identical thermal throttling after a minute of the burn-in take a look at. So whereas a horizontal place makes the Radeon RX 7900 XTX run cooler and quieter, the overheating downside was inevitable. The mounting place is only one piece of the issue, although.
Not completely satisfied along with his preliminary findings, Hartung seemed into different theories, comparable to the burden of the cooler or gravity as one of many influencers within the orientation that the graphics card is put in. The overclocker designed a customized stand to dispel each theories. He eliminated the assist bracket from the graphics card and shaved off a couple of millimeters of the stand-offs to check mounting strain. Nonetheless, his efforts have been to no avail.
The speculation of the Radeon RX 7900 XTX having a defective vapor chamber began to make extra sense. In his testing, Hartung rotated the graphics card and noticed that the temperature had considerably elevated. Nonetheless, turning the graphics card to its unique place did not assist convey down the temperatures.
Consequently, Hartung believes that the vapor chamber might have a defect, whether or not or not it’s a design downside or a problem with the selection of supplies utilized in its fabrication. It will seem that the liquid contained in the vapor chamber is dealing with circulation issues after condensation. The foundation of the issue might be insufficient strain or a liquid deficiency contained in the vapor chamber. Hartung did not have time to dissect the vapor chamber, however he might accomplish that in a follow-up video.
Whereas AMD has acknowledged the overheating issues with some Radeon RX 7900 XTX graphics playing cards, the chipmaker hasn’t offered shoppers with an appropriate resolution apart from to contact assist. Fortunately, the overheating problem does not have an effect on all Radeon RX 7900 XTX samples, however the variety of affected customers is critical, far more appreciable than victims of Nvidia’s melting 16-pin energy connector. This Radeon RX 7900 XTX overheating problem definitely does not look good for AMD after the chipmaker was mocking Nvidia for the 16-pin energy connector meltdown. Nonetheless, AMD probably has extra vital issues on its thoughts, particularly if Hartung’s conjecture proves legitimate. AMD might need to recall its reference Radeon RX 7900 XTX graphics playing cards when the push involves shove.
