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 error is by replacing the EEPROM chip itself. This process requires carefully removing the old EEPROM chip and soldering on a new one. While effective, it can be time-consuming if the chip is not actually faulty.
EEPROM ERROR? Easy solution
Fortunately, there’s also a much easier way to fix EEPROM errors without soldering—by using an EEPROM programming device.
As shown in the image below, the device has two main functions: “Read EEPROM” and “Open EEPROM.”
- If you already have the EEPROM file for a specific model (such as the Antminer S19) saved on the device, you can simply connect it to the hashboard and use the “Open EEPROM” option. Choose the correct EEPROM file and press OK. The connected hashboard will then copy that EEPROM data—almost like a copy-and-paste function.
- Use the “Read EEPROM” option if you want to save an EEPROM from a working hashboard onto the device. This allows you to reuse that EEPROM file later for another Antminer S19 hashboard.
By understanding how to use the EEPROM tool, you can save time and avoid unnecessary soldering when repairing Bitmain Antminer hashboards. This method is especially useful when handling multiple units at a repair center.
