I LIKE CLAYMORE--
It is like an old, comfortable shoe, runs very reliably, and can be tweaked with the right drivers.
BUT, my 1080ti gets 1990H/s with XMRv8 using XMR-Stak. My old i7 2600 CPU went to 230H/s vs. 90-110 H/s on XMRv7. I'd rather run Claymore, it has built-in watchdog and monitoring. XMR-Stak is not easy to tweak, but somehow, it runs like crazy on my 1080ti. My old 750ti cards perform about the same, XMR, XMRv7, XMRv8. --scryptr
What is your 1080Ti setting for Stak?
PRETTY MUCH DEFAULT--
I let XMR-Stak generate a default setting. Then I add threads one-at-a-time, for nVidia. For AMD, I add multiples of 8 to the intensity setting. When the performance drops, either type of card, I back off a little.
Claymore doesn't run on nVidia, I know, but the latest algorithms aren't supported by Claymore yet. I think Claymore will code in the new algos soon. --scryptr
