Just got my rig up and running mining ETH on Claymore. I have 6 GigaByte GeForce GRX 1070 Windforce OC GPU's. I have heard they are suppose to be able to reach up to 32 MH/s using 140W each, but I have not been able to get to that point.

Currently I am getting between 29-31 MH/s, for a total of 183-185 MH/s using 1050W of power. It seems some of my settings must be off on my overclocking. I actually bought this card because I thought it was overclocked out of the box, but I guess not fully.

I had it running at 9500MHz Memory, getting 32MH/s but it was unstable and kept crashing. So far below is the best that I have gotten.

Here is a picture of my GigaByte Xtreme Gaming OC Settings:

I am new to Overclocking so I don't really understand what I should be modifying to get the best MH/s per power usage. I am also curious if it would be more profitable to dual mine. I would appreciate any help very much!

Edit:

I have fine tuned the settings further to achieve the most stable setup:

31MH/s on each card
Core Clock: 1657/1847 MHz (Current: 1671 MHz)
Mem Clock: 9500 MHz (Current: 9104 MHz)
TDP: -40%
Fans: 65%
768W

ETH is primarily wanting you to max your memory clocks - it would appear you've already done so.

 Keep in mind that manufacturing variations WILL change the capabilities of a specific card model, much less different cards from different or even the same manufacturer - just because one person got lucky on RAM and could overclock it to crazy levels doesn't mean YOUR card can match that.

 With that said, you should be able to drop your TDP a fair bit without having a noticeable effect on hashrate, which would help your efficiency quite a bit.



 With that said, wasting a 1070 on ETH mining is .... not a good idea, they are more profitable mining other stuff like the Skein-based coins, lbry and it's varients, the groetsl based coines, and usually ZEC and it's varients.
 It's not like you'll LOSE money mining ETH, you just aren't MAKING as much.

I was able to drop my TDP to 60%. Bringing down my total power usage to 768W. I've heard people have been able to get it down to lower, but I tried to bring it to 55% and it started affecting the hash rate.

Do you think I should use nicehash? or what other miner would you recommend?

I'd recommend poking around on whattomine - not just the comparison page as that leaves OUT the Skein coins among other MORE PROFITABLE options - and look at moving to one or more of the more profitable options.

 You could also try the profitability page on Nicehash, but that focuses on their service and isn't always a good judge for mining actual coins - it does usually give you a direction to look at though.

you need to compare your OC settings with somebody with exact the same model of your card.
e.g. the TDP can be on the paper the same but in reality it can be a huge difference ;) (my MSI GTX 1070 Gaming X 8g has TDP from 230W in reality, as per specs from MSI it has 150W....).

try to find a good value for MH/W - squezing out the last 0.1 MH/s will raise your power usage exponential and heats up your GPU with nearly no sense - with a 1070 i would aim for 29 MH/s for ETH, lower voltage, lower core clock, raise memory clock, ....

31 MH/s instead of 29 MH/s will bring you less profit on top than mining directly a better currency optimized for nvidia ;)

I have fine tuned the settings further to achieve the most stable setup:

31MH/s on each card
Core Clock: 1657/1847 MHz (Current: 1671 MHz)
Mem Clock: 9500 MHz (Current: 9104 MHz)
TDP: -40%
768W

There seems to be some fluctuation occasionally on the MH/s, maybe due to the TDP being dropped so much.

Power is expensive here (0.43 KWh... yikes)

It seems HUSH is the most profitable cryptocurrency... ETH is pretty far down there for my setup.

I guess the reason I have been doing ETH is because of it's potential future value, but I may want to switch over or dual mine?

can u tell me hashrate of 1070 card

Generally ~30 mh/s with ovrclocking however, if you are lucky with samsung memory then about 32-34mhs

@kb24nitro81  I bought the same card, what do you use the power supply? satisfied?
