It’s not strange to see some people posting complications when a new GPU or CPU launches, but there’s early knowledge suggesting that some RTX 3080 and RTX 3090 GPUs have a steadiness issue when they force close to-to or above 2GHz. Most studies have centered on 2GHz, but at minimum just one consumer explained his GPU was beneath that clock.
Reviews have begun popping up on-line of steadiness complications possible tied to GPU enhance frequencies. Acknowledged-affected designs include the Zotac RTX 3080 Trinity and the MSI RTX Ventus 3X OC. MSI’s Gaming Trio is outlined, as is EVGA’s RTX 3080 XC. These studies make somewhere around the similar claim: The GPU crashes in just one or a lot more titles, generally at all-around 2GHz. Lowering clock speeds can resolve the issue.
Igor of Igor’s Lab thinks he has an clarification for the issue. Right after referencing Nvidia’s paperwork for the RTX 3080’s PCB style and design, he writes:
The BoM and the drawing from June depart it open up whether huge-area POSCAPs (Conductive Polymer Tantalum Good Capacitors) are made use of (marked in purple), or instead the relatively a lot more high priced MLCCs (Multilayer Ceramic Chip Capacitor). The latter are smaller and have to be grouped for a larger potential.
The spots blocked off with packing containers and the set of 10 environmentally friendly rectangles are all electric power rails. If the RTX 3080 and RTX 3090 are currently being fed soiled electric power, it would make clear why the cards destabilize and crash at significant frequencies.
Zotac, for case in point, made use of POSCAPS for all six rails:
Nvidia made use of 4 POSCAPS and two MLCCs, as revealed beneath. Igor notes he’s been not able to crash his Founders Edition GPU, implying that this could be the trigger of the crashing bugs. We never know for sure that the 3080 FE does not have this issue, but so much no one reporting an challenge appears to have an RTX 3080 FE.
We never know how numerous cards are affected by this challenge. Even if utilizing POSCAPs as a substitute of MLCCs is the trigger of the issue, it does not automatically comply with that every single POSCAP-outfitted gadget has a issue. It appears to be a lot more possible that a sure percentage of POSCAP products would have troubles than that Nvidia would fall short to discover it had misinformed all of its AIBs and handed them poor manufacturing paperwork. The former could trigger some elevated maintenance premiums and grumbling, when the latter would involve the maintenance of every single RTX 3080 and RTX 3090 made to-date.
If you operate into this issue, the very first matter to check out is reducing the foundation clock on your GPU. End users are reporting that 80-100MHz often operates. Even though overclocking your GPU is unsafe if you never know what you’re doing, it is difficult to muck up a element by operating it slower.
This predicament is likely to evolve above the next handful of days as Nvidia discusses it with AIBs and investigates how finest to fix the issue. I suggest preserving an open up brain as much as what the potential trigger could possibly be, not because I doubt Igor, but because at times manufacturing assessment reveals more complications that weren’t earlier acknowledged and could not be observed from area-level evaluation.
No matter what the issue turns out to be, Nvidia or its associates have a mess they’ll have to have to clear up when also working with intense card shortages. We’ll preserve you posted on whichever the trigger turns out to be.
