I got  2 rigs.

1st rig = 2 x 1080ti..run bminer no problem
2nd rig = 8 x 1070 ...it start off with "0" sols...but after running for a while it reaches the max around 450 sols - 460 sols for each 1070 card.

Total got about 5,000 sols (1400 + 3600) this is really faster than DSTM which i get about 4800 sols

After running for 30 mins or so my rig 2, it stop mining and hang there..what could be the problem?
