One of my board is not present or dies after overclocking at 750......they use to go ok for 1 week at 700 and when i try to jump at 750 1 board crash...So i put back the original firmware to try to repair it and nothing change...i wonder if it s the hashboard or the controler board....Any soluce?

Thanks a lot

It's a trial and error process. Your ultimate results will depend on which batch you purchased, how cool you're keeping the miner/room, and some luck. To troubleshoot, I always first reboot the miner and keep an eye on it. If it can't hold the freq that it used to be able to handle, then I try to figure out what changed. In all of my similar situations, the change was always the temperature in the room (one time I moved a miner to a hotter location, another time the A/C went out). Once I got the miner back to the same room temperature conditions it was in before, it worked like before. These boxes are a little finicky at the higher freq.
