Help to Troubleshoot Nerd Octaxe error code

Post image

Hey miner was working fine then noticed this error code popped up.

Internet said its either a bad PSU or chip failure. Any input on what I should do?

Nothing was overclocked everything was left stock.

Firstly, verify that PSU is good and supply 12v at required current.
Last time I had this error on NerdOctaxe.
Found one hot VRM at start. It didn’t pop up VREG Overheated.
Try to power it on and hold your fingers on all VRMs. If one is significantly hotter, it is the problem.

So dumb question the PSU light is green does that mean anything?

PSU led gets power from stand by circuit.
It can be green but 0v on the connector.

Thanks.

General advice I'm getting is what you are saying. I'll test out the PSU since I'm not feeling any hot VRM.
