Your format is tough to read at first. Can you post a photo of the status page and copy your kernel log make sure to use the # function for your kernel.

It looks similar to an issue I had with my T9+, Have you tried restarting the Miner? If so does it Hash at full power and then drop off after a while?

i upload it now

btw after rebooting it - it came to the regular situation - well

it was fixed after the reboot

but what i can see that this spesific board had alot of HW - from what its happening ?

If it happens again, possibly within a few hours post the kernel log here using the # symbol. I'm not great at deciphering the errors but it may be helpful to some.

If it turns out to be similar to my issue; you may have a bad chip. You can check my posts and pictures in this thread. This was with a T9+. I opened my miner up with Bitmains permission to avoid voiding the warranty and found a heatsink with a scorch mark.

If your miner is still under warranty and the problem persists, you should contact their support team as you may have to send the board in for repair. If your under warranty I would contact them anyways to at least document the issue in case it pops up again.
