For the reason that launch of AMD’s RX 7000-series with the RX 7900 XTX and RX 7900 XT, some experiences have arisen suggesting that AMD-designed playing cards could also be heating as much as an uncomfortable degree—reportedly as much as 110°C on what’s often called the hotspot temperature studying on these playing cards. A lot in order that AMD has now admitted that there could also be a difficulty affecting a restricted variety of reference design playing cards.
“We’re working to find out the foundation reason for the sudden efficiency limitation of the AMD Radeon RX 7900 XTX graphics playing cards,” AMD says in a press release (through Hardwareluxx (opens in new tab)). “Based mostly on our observations to date, we consider the difficulty is expounded to the thermal resolution used within the AMD reference design and with a restricted variety of playing cards bought. We’re working to resolve this difficulty for the affected playing cards.
“Prospects experiencing this sudden limitation ought to contact AMD Assist (opens in new tab).”
This assertion follows experiences from Igor’s Lab (opens in new tab) and Computerbase (opens in new tab) which recommended a batch of playing cards may have been affected, which means plenty of playing cards might need to be returned to AMD for a repair. It has additionally been recommended by overclocker der8auer (opens in new tab) {that a} defective vapor chamber is the trigger for concern on the playing cards, although AMD has not confirmed this particular element as of but. Strategy of elimination would recommend that is the possible trigger, nevertheless.
In affected playing cards, der8auer discovered a a lot larger delta between GPU and GPU hotspot temperature readings than on unaffected playing cards. Primarily, affected playing cards undergo from remoted hotspots far larger than the common GPU temperature, inflicting thermal safety measures to kick in and throttle the clock pace.
Some customers that skilled excessive temperatures have reportedly spoken to AMD assist previous to this assertion solely to be instructed these temperatures are regular (opens in new tab) or that an RMA was not attainable attributable to an open field (opens in new tab). These complaints have been handled within the time since. Whereas it is true that prime temperatures may be simply tremendous in some circumstances, it is clear that these particular excessive temperatures are literally somewhat unacceptable.
Should you discover your card is affected by this difficulty, it’s best to contact AMD and get it RMA’d. You may verify by operating an software that lists the hotspot temperature, corresponding to MSI Afterburner (opens in new tab) (famous as GPU temperature 2) or HWInfo (opens in new tab).
I’ve been operating our assessment RX 7900 XTX (opens in new tab) to see if our card is impacted by the difficulty, and, sure, it did get fairly toasty beneath load. Even throughout a modest three runs of F1 22, I noticed a GPU common temperature of 72°C. Alright, that is tremendous. Ah, however 107°C hotspot temp… and rising. That’s certainly a highly regarded spot.
With that end result from inside my private PC case, I made a decision to mount the XTX again into our check bench, which makes use of a vertical GPU configuration. There was some discuss of this bettering temperatures considerably, although I had no such luck. The hotspot temp swiftly shot as much as 110°C, with a mean GPU temp round 81°C. The clock pace additionally dropped to round 1,754MHz, which is a rattling sight decrease than the two,300MHz Sport Clock marketed with this explicit mannequin of card.
Sadly this clock pace discrepancy on the XTX is nothing new, it is among the issues I level out as odd in my assessment. Nevertheless, the Frameview software program we use for energy and thermal measurements does not file hotspot temperature, solely common temperature, in order that vital piece of knowledge flew beneath the radar. Compared, the RX 7900 XT (opens in new tab), which is reportedly not affected acutely by the XTX’s difficulty, doesn’t see such a big dip in clock pace.
I will look additional into our card’s warmth difficulty and get in contact with AMD to see about additional investigation. Should you’re certain you are additionally affected, now’s the time to succeed in out to AMD assist.
