Zvi,
What can I do/check to have this LOOP 9 communicate with the rest of the rig? It usually comes back after a number of reboots/restarts and then fails again when the mining process is restarted for whatever reasons might be (pool communications .. etc). Eventually .. it brings the whole bottom board down, the miner then hashing at about 2.2Gh/s.
I lowered the power limits below those set by the miner itself, with about 30W per power supply. I also limited the voltage from 660 to 708 to avoid ASIC overheating (i.e. above 115 degC). The firmware is 2.4.23.
