How was the progress of this? I have two farms with more than 6 thousand s9's.
This is being tested now. Some T9's do not want to work with our motherboard. This is a rare problem, but we want to understand why.
Don't throw your s9's, they might come in handy later

We also ordered a special SHA-256 chip (ACIC) for a personal device. It will be much more effective in a small volume. Additionally, we are losing our dependence on Bitmain chips.
Of course, if you have an Bitmain ASIC you have the chips by default. This problem does not concern you. But for making our own devices, it is difficult to buy new chips in large quantities...
