Several outlets have claimed that the Nvidia GeForce RTX 3080 tends to crash when overclocked to two. GHz or outside of, as we documented earlier this 7 days. The perpetrator might be minimal-high-quality parts applied in RTX 3080 cards created by AIB (include-in board) companions.
This news will come from Igor’s Lab, which uncovered that some variations of the Nvidia GeForce RTX 3080 use very low-top quality capacitors on the PCB of the card, ensuing in very low-high-quality electricity shipping. Igor’s Lab uncovered that some AIB RTX 3080 playing cards (in specific the Zotac Trinity) use POSCAPS (Conductive Polymer Tantalum Solid Capacitors) as an alternative of the additional costly and usually better MLCCs (Multilayer Ceramic Chip Capacitors).
The RTX 3080’s reference board layout allows for possibly taste of capacitor, but POSCAPs can not supply thoroughly clean ability to the GPU as nicely as MLCCs can.
Evaluating Zotac’s board design versus Nvidia’s own Founder’s Edition (FE) variant, the Zotac card makes use of six POSCAPs even though the FE card takes advantage of four POSCAPs and two MLCC clusters. As a result, Igor’s Lab reports that the Zotac card crashes when overclocked to 2.01 GHz, though the FE can overclock “very evidently further than 2 GHz.”
Other AIB RTX 3080s appeared in the report, such as MSI’s Gaming X Trio, which uses five POSCAPs and a person MLCC, and the Asus TUF Gaming GeForce RTX 3080, which works by using only MLCCs in all six places. (This may well clarify why Asus’ RTX 3080s have carried out nicely.)
Even though OEMs and Nvidia have been mum on the concern, EVGA notified its discussion board customers that it encountered troubles when working with 6 POSCAPs in their layout. Some of these six POSCAP cards ended up with reviewers, but EVGA revamped the board structure to use 4 POSCAPs and two MLCC clusters, which prompted a retail hold off.
When this need to however be considered a rumor until eventually Nvidia or yet another OEM confirms that capacitor good quality is the purpose driving the overclock crashes, it is a thing to retain an eye on. If you’re imagining of obtaining an RTX 3080, it’s well worth a fast seem to see what form of capacitors it utilizes right before finalizing the acquire.
