Are there any places that repair these
Hash boards?

I just received my Full Apollo Package for BTC mining on 8/23/2021.  I've set it up, and 2 of the 3 machines appear to be working just fine.  However, the 3rd machine just has a solid red light and doesn't do anything.  When I secure power and restart, the red light flashes quickly, and the fan will spin for a second.  After about 20 seconds, the red light turns solid and nothing else happens.  I've made sure all the cables are securely in place, but there is nothing else I can think of.  Is there something else I could try?  Or is this unit dead?

I  seem to have been able to fix this issue. I did two things:

1) Increased the size of the USB drive from 64gb to 256gb (still used a samsung EVO though)
2) Increased the size of the swap file from 370mb? to 1gb
     a) sudo swapoff -a.   
     b) sudo dd if=/dev/zero bs=1M count=1024 of=/media/usb/swapfile
         (this command took almost 30 minutes to complete with no indication on the screen what was going on, so be patient)
     c) sudo swapon -a


I've now been running the node for 12 hours, monitoring it with htop and the CPU and mem usage are both way down. I  was able to get past the 96.62% mark during the blockchain sync, which is where its been hanging up for me.

Hope this help someone else out.

Is it fair to say that if you have a standarx version running off of a full  version of the Apollo BTC then you are effectively doing Parallel processing?

Fan question:

1) The fan at the top on all three of my LTCs (all purchased used, some barely, some ran quite a bit) never turns on.  Is that normal?

2) One of them, the other fan is making a noise like its bearing is going out.  Does anyone know what the sizes of these fans are and if they're 3 or 4 pin?


Thanks

Has anyone tried replacing the fan on the FutureBit PSU yet? The supply that came with my Apollo LTC is no longer spinning, but the power supply itself seems to be operating just fine.

Hello Together,

Acctually i found no new LTC Pod. So i buy one on Ebay.
But i mean this one had a Problem.

The Temp. ist very High  in Balance Mode i have 77 degree Celsius
I have a 7% HW Error
The Fan run at 3000rpm
The Hashrate is only 100-110MH/S

I cleaned the cooling an insert a new SD with the newest Firmware.

But i didnt get down the Temp, the Fan speed and the HW Errors

Had Anybody an idea what can i do next.

Thanks for your help

I have two Futurebit Apollo LTC Miners, both with burned connectors (also both of my APU-200 Units). I suspect that happened when I setup them for run the LTC Node. I have 4 Apollo LTC Miners in total, and only this 2 have this "burned connectors" problem. I stopped the Node and the overheating diminished instantly, One of the units is still working fine but the other is in bad shape. I started looking for someone to fix them and somebody in the Forum recommended this user "lightfoot" for repair Miners with burned connectors. Cheers to this amazing Forum!!
