Hey guys wondering if anyone has figured out a possible solution? I tried switching my T1's to performance mode and I'm getting the "Error - failed to recv spi data" on two of my machines. On one all hash boards are down and on the other one board is down.
In performance mode you're overclocking them. There is no guarantee that you'll have enough power at that level, nor that the chains will be stable. You need extra power and aggressive cooling to make it likely to work, but even then it's not guaranteed.
