Low-quality capacitors could be the cause of Nvidia GeForce RTX 3080 crashes – Notebookcheck.net

It’s no secret that the Nvidia GeForce RTX 3080 looks to bear anguish with stable overclocks. The fly within the ointment will be the usage of low-quality capacitors, as chanced on by Igor’s Lab. Some AIB playing cards use more reasonably priced and no more efficient capacitors, which inhibits the provision of shipshape energy to the GPU, maybe ensuing in a atomize.

More than one shops bear claimed that the Nvidia GeForce RTX 3080 tends to atomize when overclocked to 2.0 GHz or past, as we reported earlier this week. The culprit will be low-quality parts aged in RTX 3080 playing cards made by AIB (add-in board) partners.

This news comes from Igor’s Lab, which chanced on that some versions of the Nvidia GeForce RTX 3080 use low-quality capacitors on the PCB of the card, ensuing in low-quality energy provide. Igor’s Lab chanced on that some AIB RTX 3080 playing cards (namely the Zotac Trinity) use POSCAPS (Conductive Polymer Tantalum Staunch Capacitors) as a substitute of the more expensive and infrequently higher MLCCs (Multilayer Ceramic Chip Capacitors).

The RTX 3080’s reference board fabricate permits for either taste of capacitor, but POSCAPs can no longer elevate shipshape energy to the GPU as correctly as MLCCs can.

Comparing Zotac’s board fabricate in opposition to Nvidia’s comprise Founder’s Model (FE) variant, the Zotac card makes use of six POSCAPs while the FE card makes use of 4 POSCAPs and two MLCC clusters. Which capability that, Igor’s Lab experiences that the Zotac card crashes when overclocked to 2.01 GHz, while the FE can overclock “very clearly past 2 GHz.”

Other AIB RTX 3080s regarded within the anecdote, including MSI’s Gaming X Trio, which makes use of 5 POSCAPs and one MLCC, and the Asus TUF Gaming GeForce RTX 3080, which makes use of most productive MLCCs in all six spots. (This could level to why Asus’ RTX 3080s bear performed correctly.)

Whereas OEMs and Nvidia bear been mum on the be anxious, EVGA notified its forum users that it encountered concerns when the usage of six POSCAPs of their fabricate. These kinds of six POSCAP playing cards ended up with reviewers, but EVGA revamped the board layout to use four POSCAPs and two MLCC clusters, which caused a retail lengthen.

Whereas this might maybe maybe maybe honest nonetheless nonetheless be idea about a rumor unless Nvidia or every other OEM confirms that capacitor quality is the reason within the relief of the overclock crashes, it’s one thing to retain an impress on. Whenever you’re pondering of searching for an RTX 3080, it’s price a short glimpse to glimpse what form of capacitors it makes use of sooner than finalizing the use.
