i have build my 4th rig and i have some annoying issues with 2 GPUs. My cards are running on 29,3 MH/s and i am fine with that. When i start my ethminer all 6 cards run on 29,3 hashrate, but 2 GPUs start dropping slowly in their hashrate.
At the beginning:
This is the result after 4 minutes running:
After 8 minutes running:
And this finds its bottom at [email protected]
~23,5Mhs and [email protected]
~ 24,5 Mhs.... Total hashrate @ 164 ~Mhs.
