Note: Be weary of rigs who state they only work with a specific pool.

This rig is not compatible with low diff, please set the diff >= 65536
This can usually be done on the pool by:
* setting the miner password to d=65536
* or choosing the highest diff port if your pool if you have a choice (sometimes called the nicehash port)
Or look at the pool FAQ for info on setting the starting difficulty

Mining will only start after the correct difficulty is set, it can take a few minutes to reach the quoted speed.
If it still doesn't work you will be automatically refunded 12 hours after the rental finishes.
