Overlock GTX 1070 can increase hashrate to 510~520+ Sol/s, each card.

But it's may be unstable(crash, black screen etc.), you need to do some test, find the right settings of your card.

Overclocking memory on a GTX 1070 doesn't seem to help noticeably IF at all on equihash mining - overclock CORE does help some usually.

Might depend on the specific card though.

My Gigabyte 1070's and 1070ti's definitely benefit from both core and memory overclock. I have done extensive testing and both seem to increase hashrates independently, around 5 to 15% I only mine equihash.

I didn't say anything about 1070 ti cards here - and do keep in mind I'm the one Voskcoin credits with the "+200 +700" settings he used in that first 1070 ti equihash rig video of his. 9-)

Many of my 1070 cards ARE Gigabyte, and dropping memory from +500 (as high as they go and stay stable) to -500 had ZERO effect on hashrate.
Might be power level related, since I'm running them around 105 watts for EFFICIENT mining, not pushing them for max hashrate.
Might also be a difference between LINUX and Windows or the specific drivers, but I doubt that.

My 1070's run with a +650 mem overclock (totally stable) and reducing that to zero or even only +300 reduces hashrates noticeably. I run my cards at 65% which equates to around 120 watts. Running on Windows 10 with the latest drivers.

Mine is close.. What do you have the Power limit at? And core clock/temp limit?

Like I said, power limit is set to 65% on all cards. Temp limit is 70 celsius. Core/Mem is 200/700 for the 1070ti's and 120/650 for the 1070's. Took me many days of testing to find the highest clocks that are stable for my cards.

I get around 500 sol/s (4.3 sol/w) on the 1070ti's and 460 sol/s (3.9 sol/w) for the 1070's.

Thanks,. . "120/650 for the 1070's",,.. I had mine at 140 core and about 550mem... not sure if it matter to have them switched around a little or not.
