Low-Quality Capacitors Might Be The Reason Why The Nvidia GeForce RTX 3080 Keeps Crashing

Users of the Nvidia GeForce RTX 3080 across the world appear to have problems with stable overclocks of the GPU.

The reason why the GPU keeps on failing might be the fact that it includes low-quality capacitors in its construction, as Igor’s Lab pointed out.

Some AIB cards use cheap capacitors, with higher tolerances (more margin for error), which block the GPU from delivering top-performance, often resulting in sudden crashes.

The Problem

Various outlets spoke about how the Nvidia GeForce RTX 3080 tends to crash when over 2.0 GHz or more.

Some AIB (add-in board) partners used low-quality components to develop the RTX 3080 PCB, which provoke low-quality power output.

The cards, notably the Zotac Trinity, use POSCAPS (a variation of Tantalum Solid Capacitors) as an alternative to MLCCs (Multilayer Ceramic Chip Capacitors), which are typically more expensive and usually better.

The RTX 3080 layout allows for usage of either POSCAPs and MLCCs, but the former ones aren’t available of delivering clean power to the GPU as the later ones do.

Compared to Nvidia’s Founder’s Edition (FE), Zotac’s variant uses six POSCAPs, while the FE version uses four POSCAPs and two MLCC groups.

In conclusion, Igor’s reports prove that Zotac variants crash when overclocked to as little as 2.01 GHz, while FE variants can overclock “very clearly beyond 2GHz.”

Other AIBs frequently mentioned were MSI’s Gaming X Trio, which uses five POSCAPs and one MLCC, and the ASUS TUF Gaming GeForce RTX 3080, which uses MLCCs in all six spots, probably the reason why ASUS’ GPU performed so well.

If you are looking to buy a 3080 GPU, make sure that you check twice before choosing one!
