Message 141495 - Posted: 7 Jul 2020 | 20:26:47 UTC

I saw a 3 years old topic talking about overclock a GPU to maximize crunching.

Is still a good advice to make a +5% overclock for core clock and -15% the memory clock?

What's the best setting in 2020?

Depends on the generation of GPU... if it's one of the more recent Nvidia ones, maximize power budget and increase fan curve and you should be good to go.

Our usual stance on overclocking is "Don't do it unless you know what you're doing and know how to ensure a stable overclock".
Example from the Aussie, Aussie, Aussie! Oi! Oi! Oi! Summer Solstice Challenge announcement post:
IMPORTANT: overclocking -- including factory overclocking -- on Nvidia GPUs is very strongly discouraged. Even if your GPU can run other tasks without difficulty, it may be unable to run GFN tasks when overclocked.


Some GPUs on some subprojects are memory-bottlenecked (IIRC, 2080 is memory bottlenecked) so lowering memory clock won't help you.

Your account is not showing any credit yet, nor is it showing any computers attached. Maintain a steady basic output first before going anywhere near overclocking.
