GTX 1070 full potential?

Postby NGBRO » Sun Jul 09, 2017 9:31 am

Just got myself a mini-ITX sized GTX1070 from Gigabyte a few days ago. Ran it for a day at its stock settings and noticed the PPD to be around 540K to 575K for various Core 21 projects. So I tried a modest stable overclock on GPU clock and MEM clock and PPD went up to ~615-630+K. However, from GPU-Z, I see that the GPU seems to be continually limited by TDP limit (which I already pushed to max 112% on AORUS Engine) and Vrel from the perfcap monitor. GPU clock keeps going up and down (1898-1987MHz) , load is 75-99% (varying too). Have no problems of thermal throttle at this OC, fans running 100% and temp is same as when running stock clocks.

So I'm wondering if there is any way I can improve on the overclock, such that the GPU clock and load stays at a more consistent rate and the perfcap doesn't show as much intermitten Idle time.


EDIT: Now on P9415, TDP stays within 75-105%, GPU clock stays constant and Vrel is the only cap while there's very little idle time. PPD hovers around 634-650K. GPU load seems to be lower on this project though.

Look about right to me (depending on the RCG for project 10496, 615-630+K is the range that 1080s are getting, so all's definitely good there).

Yeah, your running right in the ball park for a 1070, some projects do vary a bit, 1049x being one of the "slower" projects. Different 1070 cards also have different clock speed's and some users overclock. Of these some users like yourself put a modest overclock on and others take it to the extreme.

Anything 520-700k is "normal"

I noticed the P1049x ones take up more power and resources to fold, hence constantly causing the GPU to hit both Power and Vrel caps and reflecting a less consistent performance as compared to P941x tasks, which I see put less GPU load and allow the GPU to hit a higher and more consistent clock with only Vrel as cap.

So I guess that is normal for some "more intensive" tasks to cause GPU to have more "Power" (i.e. TDP) and "Idle" as perfcap reason? Afterall, end of day, PPD for the projects still stay within the same range, I noticed.
