Does anyone's hashrates fall after some time with dstm? I've got 8x1070's and I start around 3,700-3,800 sols and it eventually settles around 3,500-3,600 after about 1 hour.
Only time I've notice a measurable decrease is when it gets hotter. If it stays cooler I'll get higher hash rates (just starting the program from a cool down) and will slightly decrease a few hashes after really 10-15min at most. If you watch it you'll see the decline yourself in the manager.
