hi,
right now, sli working perfect but wanted to do some overclock tweaks,
brand im using is MSI GAMING X GTX 1070 and ASUS Gtx 1070 DualFan OC edition,

the problem is i wanted to decrease temp and power by adjusting power limit,
on both card i applied core clock at 150 and +core clock to 200mhz
with power target to 63% to MSI and ASUS to 80%
i think the asus card is bit small,
with 63% of power target temps went down to 58c for both cards,
MSI AVG CORE CLOCK 1925mhz with 63% power target
and ASUS Average core clock 1873 with 85% power target but same OC settings
would this create problem in games?
at 100 it reaches 1950+ avg core clock

would different Mhz cause problem?

Should stick to forum rules and not double post.

If it works, don't break it. I had two 780's not always get the same exact clocks and run fine, though with that SLI is basically dead now.

Yup, should've chosen 1080Ti over 1070 SLI. Lower cost and more consistent performance.

1. Well with 1 card already in hand, SLI would normally have been the logical / obvious upgrade choice. But since the 10xx series, with no competition from AMD from the 1060 on up, it's simply not in nVidia's interests to improve SLI perfomance at lower resolutions since the only cards hut by thids would be nVdias own cards. And while nVidia has maintained SLI performance at 4k, at 1080p scaling is only 18% and at 1440p, only 33% ... well below the 70 - 101% scaling we say with 9xx series where twin 970s killed sing;le cards above it.

2. Yes, you can use cards of different speeds (MHz) but combined SLI performace will be limited by the lower card. And by reucnmg the power target, you are putting a huge nerf on the cards perfoirmance to a point where it will be tough to see any performance improvement.... might even see decreases.

3. I don't quite understand the desire to reduce temps as no mention was made for throttling. At load w/ OC temps on the MSI 1070 Gaming X hit 72C, 10C below 82C at which any higher temps would induce throttling.

4. If temps are above 82C, then the course you have taken might be logical but only after other solutions hav ebeen addressed. The top card in SLI, can be as much as 10C hotter due to the bottom cards exhaust air being used as intake air for the top card Most common solution being a 1500 rpm fan mounted on back of HD cage, blowing fresh air from the front grilles and case bottom into the space between the cards.

5. Is case ventilation adequate ? With 2 x 200 watts for the cards and figuring 130 for the CPU and 30 for the MoBo, that's a potential 560 watt thermal load ... with 140mm fans (75 - 100 watts of cooling per fan if you want a quiet system), that's 5 - 6 case fans.... with 120mm (50 - 75) , I'd want 7 - 10.
