Title: EVGA 1070Ti Overclock issue Post by: East113 on December 22, 2017, 05:50:37 PM 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!

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 SMOS overclock settings Core 200,200,200,100,200,200,200,200 Memory 700,700,700,600,700,700,700,700 Power Limit 146,146,146,132,146,146,146,146 My Current Settings due to the size of the PSU powering this rig, Title: Re: EVGA 1070Ti Overclock issue Post by: QuintLeo on December 23, 2017, 07:58:09 PM 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.
