Well i just checked my miner and the speeds are all over the place, if you look at pic one of the asics, chain #1 has a - instead of a 0.

The miner status page speed matches the speed on the mine display.

Which card is this, at what end of the machine, can i just remove it, clean it etc.....

Cheers

I don't think cleaning the card will solve the problem. It's seem like failing chip.
As long as it's didn't cause problem to the chain, you are fine.

I is still in bits i wonder what will happen if i power down again !!!!

Is it really critical to get a code 10 sd card ?

If so i will update miner to latest files etc, then create am image and put it on one as a spare...

1 - does the card have to be removed from unit/plugged in pc to create the image or is there a 'back-up' menu in the miner interface ?
2 - what program do you recommmend to create the image.

cheers

If you didn't move the miner, i guess it's will be alright Cheesy

Otherwise just pull out the blade again Grin

You need pc to write the image. If using windows, Win32DiskImager is the choice.

Check if there is any loose connector. Clean all accumulated dirt.

Where am I?

Sounds like the card is dying. I had the same problem required multiple reboots to get them to come one online. Finally it died, bought a brand new Sandisk SD card and everything works perfectly.

Have you tried the reset button located near the display?

Where is the reset button near the display, i thought they were only on Rev C Beaglebone ??

https://www.bitmaintech.com/files/download/Antminer%20S2%20Manual_EN.pdf

I have never heard any beeps and the reset does nothing at all, the BBB (Beaglebone) has 4 green/1 red and no blue.

If its not the SD card/image then it must be the BBB but i do not understand how to replace it....... Embarrassed

Do i just insert the SD card with my image on it ? Totally confused about the reset buttons etc as you can't get to them when the BBB is in the rack Huh

How do i know what version/batch i have ??

I have this problem exactly, can i try just using a new 4Gb SD card with the image first ?

Can i write the image with a program like Win32 Disk writer and rename the folder as BTMBOOT ?

Anyone help me out please.

Thanks
