Hi all,

I'm not sure whether this is even an issue at all, but I find this a bit weird.
Today I have added another card to my machine, a GTX 1080. I already have 2x GTX 1080 Ti, all cards are watercooled.

In Awesome miner I have created two miners, both using the same pool (miningpoolhub), both mining Vertcoin. The first miner uses my 1st GPU only (1080 Ti) and the second miner uses both my 2nd and my 3rd GPU (1080 Ti and 1080). Using ccminer, by the way. The reason for the miner split is that when I am gaming, I turn off the first miner and use my first GPU card to play while the other two cards continue mining.
The issue, however, is as follows:
- The first miner, with a single 1080 Ti and a hash rate of 61 MH/s (intensity 18), finds slightly more shares than the second miner which has 1x 1080 Ti and 1x 1080 with a total hash rate of 121 MH/s (intensity 20). This is contrary to expectations and I don't understand this behavior.

Anyone knows what's happening? Why is the second miner finding less shares than the first miner, even if the hash rate is double?

The stratum difficulty could be higher on the 2 card system resulting in fewer shares per minute. Check your stats on your pool if they allow that.
