Core or Memory overclock?

GTX 1060 6GB Zotac AMP!, stats: 1961/3948 (actually 100+ core/150+ memos overclock manual by), 285~290 sol.

What i have to do for better perf? OC the core, the memos, both?
I heared about underclocking the core and overclocking the memos (for better sol per watt) so memos are most important to OC?.
What really affects hashrate?
Ty guys.

Zotac GTX 1060 AMP! 3GB memory Hynix

I have 1070 amp extreme cards. I use +75 core, +600 memory. Memory is much better than core for mining.

Memory never does anything at all for my hash rate while mining zcash no matter how much I increase it. Core makes all the difference for my 1080 Ti cards.

Same here I do -200 mem on 1080 ti core +60 power at 68% 630sols at 165w temp around 50-55deg

hello @lukrom I mine with Giga 1080ti Extreme with similar specs. I adjust just two of them:
1. -200 mem
2. core +60

I get 725 Sol/s in average with higher temps (70 - 76C). So, my question is why do you decrease power? Does it make serious profit in some way?

This 6 gpu in a case,the temperature is slightly higher.

Hi as I said in other topic my power cost is v high 0.17usd so I have to look for most eff settings ;-/ if I would have it for 0.1 as some people in USA i would not be bothered and ovecl than underclock... I m now 640 sols on 170watt if i wish to go up 715 for 250 watts so it is not profitable for me as it gives 1.1 sol/watt ...

I changed both
