1. I am trying to find the optimal OC settings for these cards, while stable. I've heard to try and OC each card individually. How can I do this in afterburner and save the profile, so that on a reboot all of the cards use those individual settings? It seems like in afterburner, when you individually OC the cards, the profile does not save for all cards, only one.

2. Does anyone have any OC settings for these cards so I can baseline off of?

3. The 3 GPUS at the end of my rig are a lot hotter than the others. (these cards just spit the hot exhaust above and get sucked into the ones after it) What is the best way to Exhaust some heat away? Put a fan above the rig and exhaust the hot air upwards? Or blow cool air towards the front of the rig(the front of the cards).

Thanks!!

The Ti SC Black edition series is my favorite 1080 and 1080TI. They run perfectly, cool easily and overclock great. When you install Afterburner it will automatically link the GPUs together so that any changes you make will be applied to all of them. Since they are all the same, it will be much easier to overclock them than if you had different models. The Tis usually run ok with +100-+125 on core and +75-+100 mem. I always max out the power draw to 120%, then apply my overclocks. After I find a good setting, I slowly reduce the power limit until my hashrate goes down. No matter the brand, the 1080 chip can run about 2100 core and 4700 on the memory. The Tis can run around 2050 core and 5100 memory. My goal is to slowly apply the overclocks until I can get the card to hit those speeds. Above that, they start to crash.

You have very slow memory clocks. 5400-5600... is usual for them
