I'm getting thousands of HW errors and 10% rejects. A reboot does nothing. How can I solve this problem?
First contact bitmaintech. Second check for any x or - in ASIC status.
Try removing the heatsink over ASICs and check for overuse/leak of thermal paste.
Clean it and reseat the heatsinks, don't forget to use thermal paste or thermal pad.
Hope you are running all at default, also post a screenshot of your status page.
