If you are maintaining a farm or repairing individual units, you’ve likely encountered a situation where all ASIC chips test fine, yet the hashboard refuses to start or the control board fails to recognize it. Often, the culprit isn’t the power circuit or the ASICs, but the Antminer S19j Pro EEPROM chip. What is an … Read more
EEPROM Error When running Bitmain Antminer S19, you may sometimes see an EEPROM error, especially after swapping a hashboard from another miner. At crypto miner repair centers, it’s common to consolidate machines by exchanging hashboards, and that’s when EEPROM issues often appear. As mentioned in a previous article, one way to fix an Antminer EEPROM … Read more
When repairing hashboards, the main goal is to get all ASIC chips to pass successfully. A fully working board will display green indicators across all chips when tested using a hashboard tester. However, even when all chips pass and show green, the miner might still not hash properly. One common reason for this is the … Read more
