TECH NEWS – AMD may have made a severe mistake with the reference graphics cards (not the custom models designed by third-party companies!).

AMD ended 2022 with a blunder, as the higher-end Radeon RX 7900 XTX reached 110° in use for many users, which led to the card lowering its clock speed to avoid overheating, resulting in lower performance. When initially affected users tried to contact AMD for an RMA, the company drove them away because they said it was customary to have this temperature during usage. They have turned around since AMD recommends contacting their customer support.

And DerBauer has published his second video on the overheating issue. He has heard of 48 (!) cases so far, and some people have sent them their video cards to investigate why AMD’s Radeon RX 7900 XTX reference cards are getting so hot. So far, we thought removing and reinstalling the cooler and applying the correct pressure would solve the problem, but it might be more severe than that, as it doesn’t solve the manufacturing defect!

The graphics card achieved a junction temperature of 110° with both a horizontal mount and a cooler mount, increasing the pressure. He even tried replacing the spacer bots and washers freely after Igor’s Lab’s idea. DerBauer believes the fault should be found inside the cooler, specifically in the heat sink. There is a vapor chamber, and either a material usage or a design flaw prevents the liquid from circulating correctly around the video card. He will investigate this further by dissecting the block.

If it turns out that AMD screwed up, they will have to recall their Radeon RX 7900 XTX reference cards from the shops, so it’s no use the company having a big face about having a small and easy-to-upgrade cooling solution if SUCH failures can still occur!
