Gamers Should Contact AMD Support in Case of Thermal Throttling on the Radeon RX 7900 XTX GPUs [Report]

AMD has issued an advisory for users experiencing thermal issues on their Radeon RX 7900 XTX graphics cards. Calling it an “isolated event”, the chipmaker has asked gamers to contact AMD support if their GPUs operate over safe thermal limits. Data gathered by HardwareLuxx shows that most models approach the 90C mark, while some even post figures as high as 110C. These temps are far from normal and can lead to clock throttling and a substantial performance deficit.

We are aware that in a few isolated cases, users may experience unexpected thermal throttling on AMD Radeon RX 7900 XTX graphics cards (reference models from AMD). Users who notice unexpected thermal throttling on an AMD Radeon RX 7900 XTX should contact AMD Support.

AMD Statement

Earlier this month, a Reddit user observed similar behavior on his Radeon RX 7900 XTX. He asked for a refund but was shot down by a company representative claiming that 100C+ temps are normal for the RDNA 3 flagship.

Hi everyone,

As we know so far, Quite many people have problems with the refererence 7900xtx cards, reaching 110 Junction Temps, 100% fan Speed and still loosing performance due downclocking .

I just got the reply of my RMA request:

————————————

Thank you for your email.

The temperatures are normal if you there is any issue please, contact us back.

Thanks for contacting AMD.

Further investigation by Der8auer revealed that these thermal issues result from sheer manufacturing negligence. AMD has been using low-quality thermal paste and pads with inappropriate mounting pressure to cool the Radeon RX 7900 XTX. Replacing the same with aftermarket components fixes the problem. Subsequently, manufactured RDNA 3 parts should rectify the problem.

On a related note, AMD has locked the power tables on the RDNA 3 graphics cards. Modifying power play tables is a commonly used method for overclocking and curve tuning. Since you’re editing the Windows registry rather than firmware or hardware, you don’t run the risk of voiding the warranty or bricking your card.

The Radeon Adrenalin Software comes with an in-built overclocking utility, but despite many revisions, it’s still the worst in the category. You have very limited control over the various parameters. On the RX 7900 XT, power can only be increased by a measly 10%.
