It is no secret that the Nvidia GeForce RTX 3080 appears to get anxiousness with stable overclocks. The waft in the ointment will be the exercise of low-quality capacitors, as found by Igor’s Lab. Some AIB cards exercise more inexpensive and never more effective capacitors, which inhibits the delivery of excellent energy to the GPU, possibly resulting in a atomize.
More than one retail outlets get claimed that the Nvidia GeForce RTX 3080 tends to atomize when overclocked to 2.0 GHz or beyond, as we reported earlier this week. The perpetrator could possibly well possibly be low-quality parts susceptible in RTX 3080 cards made by AIB (add-in board) partners.
This knowledge comes from Igor’s Lab, which found that some variations of the Nvidia GeForce RTX 3080 exercise low-quality capacitors on the PCB of the card, resulting in low-quality energy delivery. Igor’s Lab found that some AIB RTX 3080 cards (in say the Zotac Trinity) exercise POSCAPS (Conductive Polymer Tantalum Real Capacitors) slightly than the more costly and usually better MLCCs (Multilayer Ceramic Chip Capacitors).
The RTX 3080’s reference board invent lets in for either flavor of capacitor, however POSCAPs can no longer hiss excellent energy to the GPU apart from to MLCCs can.
Comparing Zotac’s board invent against Nvidia’s contain Founder’s Model (FE) variant, the Zotac card uses six POSCAPs whereas the FE card uses four POSCAPs and two MLCC clusters. In consequence, Igor’s Lab stories that the Zotac card crashes when overclocked to 2.01 GHz, whereas the FE can overclock “very clearly beyond 2 GHz.”
Other AIB RTX 3080s seemed in the document, including MSI’s Gaming X Trio, which uses 5 POSCAPs and one MLCC, and the Asus TUF Gaming GeForce RTX 3080, which uses most sharp MLCCs in all six spots. (This could increasingly possibly well disclose why Asus’ RTX 3080s get completed successfully.)
Whereas OEMs and Nvidia had been mum on the anxiousness, EVGA notified its discussion board customers that it encountered considerations when the exercise of six POSCAPs in their invent. Pretty quite loads of these six POSCAP cards ended up with reviewers, however EVGA revamped the board structure to exercise four POSCAPs and two MLCC clusters, which introduced on a retail prolong.
Whereas this could well possibly well aloof aloof be regarded as a rumor except Nvidia or one other OEM confirms that capacitor quality is the reason on the support of the overclock crashes, it’s something to preserve an peer on. Must you’re thinking of buying an RTX 3080, it’s price a short leer to survey what more or less capacitors it uses earlier than finalizing the hold.
