First Time Overclocking GPU

TriedandTested · 10 Apr 2017 at 20:52

Just got a new card, but don't know where to start really. Want to push this card a little and here's where it sits now. Air cooled. It's a Zotac GeForce GTX 1080 AMP Extreme Spectra. What should i start with? Are the 0Mhz basically indicating stock values? 1+ over that is where the overclocking begins?

Put power limit at maximum, add +100 mem and then benchmark, if it artifacts / crashes (highly unlikely) drop to +80 etc... etc... or if it doesnt crash add +120 core.. keep tweaking / benching until it becomes unstable, revert to previous stable clock, then do the same for memory.

you can also unlock the voltage limiter to allow a little more juice which is safe as it will only let you go to 1.093v (100% on slider) - im not familiar with firestorm s/w bit MSI afterburner its done with checking 2 tick boxes in the meu.

Yes 0mhz/stock settings always load by default. you need to save a profile and check 'apply at startup' somewhere in your software

Thanks. I'll give those suggestions a try in the week. What's the difference between GPU clock and memory clock out of interest?

The higher the stable GPU clock (core frequency) the faster the GPU. GPU Memory overclocks have little effect on performance ~1-2fps in my experience.

In my experience with pascal, you can o/c memory from 0 - +700mhz card lottery. GPU core 0 - +120mhz on air.
