running several ASUS B250 mining expert and this an issue we just can not get around and dont seem to be able to fix it.
Using RX570s from Sapphire, with a simple OC they run between 29 and mhs for Ethereum on Nanopool. So far so good.
13 GPUs are connected to 1 rig, using proper risers.
Out of the blue, ALL cards drop to a max of 3 mhs and there is absolutely no way of recovering.
- Rebuild the rig - Done, no success. They mined for 10 min on high speeds, then back to the original issue.
- Tested other PSUs - Done, no success.
- Reinstall - Done, also no success. Workes for around 10 min, then they crash again.
- BIOS update - Done, does not matter which bios we run. Latest and older version show the same error.
Does anyone have any clue? Desperate here!
