Hello,
I have two V2 blades and a cube connected to Slush's stratum proxy. The hardware itself seems to be in good shape, all three devices achieve the desired hashrate but after about five minutes - they restart. Every time this happens they need a few moments to get back up to speed and in the process I lose tons of hashes. The blades average out at only about 7.5Gh/s (out of 10Gh/s) while the cube averages only 25Gh/s (out of 38Gh/s), I'm guessing since it takes longer to reach its target rate upon restart.
So far I've tried different pools and exchanged the power supply to see if those could be the problem, but the results were the same. Honestly any information would be greatly appreciated and I'll tip whoever can make this go away. I feel like a noob for not being able to figure this out, but I'm treading in the dark.
