Re: Can´t find the sweet spot with my GPU - Help wanted: evga 1070 SC Black edition
Hi everyone.
I recently got my first rig up and running, but i'm having problems finding the sweet spot for good hashing rates.
Is there anyone who can give a quick glance and take a look ?
This is my typical hashing rate for zcash:
EVGA GTX 1070 SC Black Edition, Micron mem.
Zec Miner 0.3.4b
GPU0: 398 sol/s, temp 62C
GPU1: 409 sol/s, temp 53 C
GPU2: 402 sol/s, temp 59 C
GPU3: 409 sol/s, temp 53 C
GPU4: 411 sol/s, temp 57C
GPU5: 339 sol/s, temp 61 C
In afterburner my settings are:
Power: 73%, Core: +114 and Mem +334
The system:
Z170A gaming pro carbon, 8 gb ram, 120 gb ssd.
Cosair HX1000 that powers MB, CPU and GPU0,GPU1,GPU2 & GPU3
Cosair VS 550 that powers GPU4 & GPU5
My hashing rate is lower than expected and I would love to get it up, to a point where payback period is less than a year
Is there anyone out there who can help me ?
What timings ? What to do ? what to look for ?
Any help would be very appreciated

I am running those on a system and am running them 85% +120 Core +700 Mem 75% fan speed. That is giving 440-450 Sol/s at 120-130W. It stays at the 3.5 Sol/W range with those settings.
73% power is too low for these single plug 1070s trying to get a good OC and you wont be able to do a high Mem if you keep the power that low.
That system is 4 1070 Black SC 4 1070 SC z270-A 8GB Ram 120 GB SSD, 2 850W Power supplies.
I have MSI GeForce GTX 1070 GAMING X 8G and I achieve 450-460 Sol/s easily at 85% +90 Core +645 Mem with EWBF's CUDA Zcash miner. This card can take a lot more punishment than my other 1070s from ASUS but there are diminishing returns in further overclocking.
Yeah the MSI is better than the 1070 Black SC or 1070 SC in general. If you run a EBGA 1070 FTW or SC2 or Aorus 1070 you can do 75% +100-125 core + 575 Mem and reach 470-500 Sol/s at a 3.5+ Sol/W
