Help OC GTX 970

Hi, i am currently overclocking my gtx 970 and am at a stage that i require a bit of assistance.

Using Msi Afterburner i have,
Increased power limit to max (120)
Increased core clock to +204
Increased memory clock to +634

Everything is stable.

My question is should I increase core voltage and attempt to increase the core and memory clock further? If so how far can it go before getting dangerous? These numbers are already higher than the youtube videos Ive been watching.

Any help would be great thank you

Probably still benches good. I don't know they want to play with the drivers it allll probably benches better. I'm getting 980ti passes that look real similar.

I think there's only 1/2 cards that have an unlocked memory voltage. The mainstream ones have a locked memory voltage.

However, you should be able to increase the core voltage (related to core clock) to 1.315V (or something around that), you can do so by modding your BIOS.

You can save your current GPU BIOS by downloading GPU-Z and using it to save your BIOS. Edit using Maxwell Bios Editor 1.36 and follow a guide here:

Flash using this tool:

You can increase the power limits massively, disable GPU boost, increase voltage to a certain point, increase other clocks on the card (e.g. XBAR, L2C, SYS), alter fan profile, disable boost, alter specific performance state clocks.

It all depends on your usage objective.


If you are using this for 24/7 and or gaming, then absolutely no need for more overclocks, the margin of gain is incredibly small and not worth it. However, if you are pushing benchmarks for hwbot scores, or something of that nature, then I would say yes, push it.


Having said that, based on the generation of card you have, I would expect more voltage would not help you. This Maxwell generation is all about DIE temperature and not as much about volts. It scales most with temperature, then once temps are subzero it scales with volts again. Some people, myself included, have literally seen more MHz from under voltage (lower vcore than stock)...because the resulting temps are lower.
