Let's look into the recommended things to do when mining with FPGAs. Mining is fun and it can also be profitable if several factors are taken into account.
Make sure that all your FPGAs have adequate cooling. Additional fans beyond what is provided by the manufacturer are always a good idea. Remove dust frequently, as a build up of dust might have a detrimental effect on cooling efficiency and hence, mining speed.
For your particular mining machine, search online for all the optimization tweaks to get all the hashing power that is possible. However, due to a large variety of mining machines, we cannot provide all the possible tweaks in our book.
When setting up a mining operation for profit, keep in mind that the electricity cost will be a large percentage of your overall cost; hence, seek a location with the lowest electricity rates. Think about cooling costs; perhaps it will be the most beneficial to mine where the climate is cooler.
