Are you getting 25% error rate each time on reboot?
3 full reboots, between 15 to 30 every time.
What pool are you running at? Try litecoinpool and see if you get the same issue.
I was running on litecoinpool. I tried both US servers, then I moved to defcoin.secdsm.com and got about the same.
If you do check the back of the miner where the PCB is, you'll see 5 spring heatsink screws. Make sure none of those springs have shifted turing shipment and are touching any components on the board (there should be a washer in between the spring and PCB to prevent that but the spring can still move).
Washer / spring looks good.
Going to move it to the workbench so I can look at a few other things.
Also, going to re-burn the sd card.
Thanks,
Dave
Ok before you do all that try this.
Go to settings, set to custom miner mode.
Set voltage to 777mv, and keep frequency at 598 (eco).
