Following numerous reports of third-party Nvidia RTX 3080 card crashes, PC makers are now trying to figure out how many capacitors are in their new GPU.
That’s right: capacitors. On Friday, concerned shoppers stumbled upon a crash theory: a site called Igor’s laboratory suggested that Nvidia’s partners are running out of capacitors used in their RTX 3080 by third parties. And over the weekend, this theory spread: many objects were cited Igor’s laboratory to publish titles such as “NVIDIA GeForce RTX 3080 Stability Issues Traced to Cheap Capacitors”
A day later, it seems that there may actually be some evidence that the capacitors may have caused the cards to crash. EVGA assessed the dispute over the RTX 3080 capacitor on Saturday, citing its own problems with the layout of the capacitor it originally used in its RTX 3080 cards, although the company claims it never sent the original layout to customers. In that note, EVGA explained that while a six-POSCAP design “could not pass real-world application testing,” it later tested a design with four POSCAPs and 20 MLCC caps that worked better.
Like Tom hardware explains, usually under the chip of a modern graphics processor there are two types of capacitors: MLCC and POSCAPS. Both capacitors have pros and cons; MLCC is smaller, but performs better at higher clock speeds. POSCAPS are larger, but not as good when operating at high clock speeds.
At this point, we don’t really know if capacitors are causing these crashes, but demand has certainly prompted the industry to respond: MSI, Gigabyte and Zotac have issued statements claiming that capacitors are not the problem and that the new Nvidia drivers can handle it. with all the stability problems in the cards. This is the position of Nvidia and today released a new driver to deal with stability issues with the RTX 30 GPU line.
PC World reports that one of the maps that previously crashed does not do so after the update. The outlet had a pre-production EVGA GeForce RTX 3080 FTW3 for review, which had the original capacitors instead of those supplied to retailers. PC World notes that there is a trade-off: the update “slightly limits” the highest clock speed when amplifying the GPU.
