Low-quality capacitors can cause Nvidia GeForce RTX 3080 crashes
Its a well known fact that the Nvidia GeForce RTX 3080 appears to experience difficulty with stable overclocks. The fly in the ointment could be the utilization of inferior quality capacitors, as found by Igor’s Lab. Some AIB cards utilize less expensive and less compelling capacitors, which hinders the conveyance of clean capacity to the GPU, potentially resulting an crash.
Multiple outlets have asserted that the Nvidia GeForce RTX 3080 will in general crash when overclocked to 2.0 GHz or past, as we detailed not long ago. The offender might be inferior quality segments utilized in RTX 3080 cards made by AIB (include board) partners.
This news originates from Igor’s Lab, which found that a few adaptations of the Nvidia GeForce RTX 3080 utilize bad quality capacitors on the PCB of the card, bringing about inferior quality force conveyance.
Igor’s Lab found that some AIB RTX 3080 cards (specifically the Zotac Trinity) use POSCAPS (Conductive Polymer Tantalum Solid Capacitors) rather than the more costly and for the most part better MLCCs (Multilayer Ceramic Chip Capacitors).
The RTX 3080’s reference board configuration considers either kind of capacitor, yet POSCAPs can’t convey clean capacity to the GPU just as MLCCs can.
Contrasting Zotac’s board design against Nvidia’s own Founder’s Edition (FE) variation, the Zotac card utilizes six POSCAPs while the FE card utilizes four POSCAPs and two MLCC groups. Subsequently, Igor’s Lab reports that the Zotac card crashes when overclocked to 2.01 GHz, while the FE can overclock “very clearly beyond 2 GHz.”
Other AIB RTX 3080s showed up in the report, including MSI’s Gaming X Trio, which utilizes five POSCAPs and one MLCC, and the Asus TUF Gaming GeForce RTX 3080, which utilizes just MLCCs in each of the six spots. (This may clarify why Asus’ RTX 3080s have performed well.)
While OEMs and Nvidia have been mum on the issue, EVGA informed its gathering clients that it experienced issues when utilizing six POSCAPs in their design. A portion of these six POSCAP cards wound up with analysts, however EVGA patched up the board format to utilize four POSCAPs and two MLCC bunches, which caused a retail delay.
While this should at present be viewed as talk until Nvidia or another OEM affirms that capacitor quality is the purpose for the overclock crashes, it’s something to watch out for. In case you’re considering purchasing a RTX 3080, it merits a brief glance to perceive what sort of capacitors it utilizes before finalizing the buy.
