EVGA 1070Ti Overclock issue

[East113]

So I was using smOS the past couple weeks but kept having issues with it staying connected to their web dashboard, although the rig did continue to mine. At first I only had one card connected and OC settings would not take, after installing all three cards the settings started to take just fine. 200 core and 750 mem. Power limit setting also took throughout the whole process at 110 watts.

After taking the OC settings I was up around 501-505 Sol/s.

Well I switched to the newer version of nvOC that Poison released and saw that my OC setting would not take in that OS either. Was stuck around the 450-460 Sol/s mark. Once again though the power limit was taking just fine.

Decided to switch back to smOS for the time being to see if the settings would work again, and now all three cards seem to not be accepting the settings via smOS either. Staying in the 450-460 Sol/s range.


Mobo - Gigabyte Z270P-D3
GPU - 3x EVGA 1070Ti

Any ideas as to what could be causing this? I have not been able to find anything anywhere online.

Thanks!

Try running the memory at 700 instead of 750.

 I never got reliability out of anything over 700 on my EVGA SC 1070 ti cards.

For SMOS and over clocking a 1070ti are you designating each card individually, if not you should give it a try, here is an example for SMOS, of some Rockstar numbers


for your 3x EVGA 1070ti

Core -200,200,200

Memory -700,700,700

Power Limit - pick one of the following based on your desired efficiency of Sol/s per watt , or tweak the numbers for percentages in between the 10% steps offered here

161,161,161                     90% power getting you top    540 sol/s  3.38 efficiency

146,146,146                     80% power getting you top    529 sol/s  3.64 efficiency

126,126,126                     70% power getting you top     509 sol/s  3.96 efficiency

103,103,103                     60% power getting you top     457 sol/s  4.46 efficiency


I learned and applied this info from QuintLeo's post on the second page, second from the top on this 1070ti thread
https://bitcointalk.org/index.php?topic=2324651.20

let us know if this works for you

for example I am running 7 x 1070ti with 1 x 970 mixed in reporting as the card three, but numbering of cards starts at 0 (zero) so the fourth setting in my string reflects the gtx970

60% power is actually 106 watts for most 1070 ti cards to date including the EVGA SC model, but anywhere in the 100-110 range gives very close NICE efficiency numbers.
