I've installed this via the web portal on one of my R4's and am having problems getting it to hash. It will submit 3-4 shares before stopping. It appears to be linked to fan speed as when the fans drop from start up, around 3k rpm, the miner stops hashing. For some reason the fans drop as low as 800 rpm (never seen them that low) and my guess is thats causing a failure mode to kick in like it does on the s9's when people disconnect the fans to try and oil cool. As there is no way to control fan speeds through BOS at the moment, I can't test this theory. I'm in contact with Braiins support and will keep the thread update with how this issue gets resolved.

The R4 is not supported, why did you do this? If you think the problem is the fan, just disconnect the 4th wire (I think its blue): gently take it out of the plastic plug by using a small flat screwdriver to let it lose; then the fan will be at 100%.
