Can overclocking permanently decrease performance?

post #1 of 5
Thread Starter 
I think I overclocked my 770 too far, until I saw artifacts, then I decreased it, and kept seeing artifacts, so I went back to stock clocks. Now that I'm at stoock clocks, it feels laggier than when I bought it originally, is this true?

I doubt you could have possibly done enough damage to make the core unstable at stock speeds, in the amount of time that the 770 has been out, which would really be the only way that it would make it laggier at stock speeds.

You probably are just used to the overclocked speeds and the stock ones feel slower.

What he said i doubt it.
Even then i think if you would have damaged your GPU with overclocking you would notice it trough artifacting on normal clocks and not by it feeling slower.

Try running some benches and compare them to other 770's on stock clocks.

Art is correct. Details on how much overclocking you did and temperature levels would help. Artifacts are generally a memory overheat issue, and not a GPU related one. You could try upping the GPU clock but going with a lower (or even stock) memory clock. For extended play I sometimes set my Titan's back to Stock memory clocks, while running the GPU clock at +30%. The reason in my case is that I have water cooling to keep the GPU stable. But the backplate doesn't do quite as much to help cool the memory.

Artifacts are normal, it can degrade if you keep pushing it. But once like that didnt harm anything.
