Overclocking my GTX 970

[Jonathan Cave]

I have 2 x Asus STRIX 970's in SLI.

I really need some help in understanding the Power target and the voltage (mv)

without touching the voltage i've achieved: +180mhz gpu core and + 150mhz memory.

I really dont understand how to push this card further. because i dont' have a clue about the mv stuff....

i have an 850w XFX PSU and 4670k @ 4.2ghz (1.25v) so i think the PSU is more than adequate, however i need someone to take me under their wing and help me tweak this futher, any takers?

Do not try to overclock anything till you know what you're doing.

Google stuff eg http://www.techpowerup.com/reviews/ASUS/GTX_970_STRIX_OC/28.html

and lots more till you are 100% confident you know what you're doing.

Actually since you aren't touching voltage and other parameters other than Core Clock and Memory Clock then I'd say you did pretty good. As long as the system doesn't crash I'd stick with what you got. Oh, and assuming temps are reasonable (under 75C at max).

If you do want to push it further then you might need to up the Power Limit but I would be happy with what you already have done. At some point the returns aren't worth it.

Great build and overclock.
fyi, I can't see that pic big enough to read it.

Have you tried pushing the memory further? I'm sure you can get it a little better than +150mhz.

@i7baby - I know how to overclock GPU's at a novice level by adjusting the power slider / and stress testing GPU Core/Memory, - it's the voltage adjustments i'm not upskilled in to know what im doing therefore i've not done anything with it. - but i want to learn.

@envy14tpe the GPU temps are ~71 which is pretty damn good considering they are overclocked and sit side by side in the motherboard. - The picture is fine, what do you see? it's a screenshot of the precision X settings i've used mate.

@Ellis_D this is the best stable o/c i can achieve

I think that'd be a handy but safe overclock.

71C under load is fantastic for this setup. The R4 isn't the best at getting lots of air in but temps seem good. I'm really impressed. Glad to see this cuz I was thinking of a new build with 970 SLI.

I have 6 x Silent series R2 fans inside (5 x 140mm 1 x 120mm)- it is VERY quiet! The fans on the GPU's dont fire up until 60 degree's which is pretty awesome.

71 deg is under full load after 2hrs of playing at 5760 x 1080 on far cry 4.
