From 4.750 to 3.200?

[opmac]

Ok since that last pic after I got a temp reading.

I bumped the freq to 550.  No temp reading registered. I then put it back to 500 freq.  No temp reading now on that

I just unplug a good card with the bad card plugged in at freq 500

asic 30 freq 500 no temp reading

bummer

Ok so I still have the cables switched around

I fired it up with freq set to 500 without unplugging a good board yet.

This time i also got a temp reading on the bad board.

Just wanted to post this info before I actually unplug one. Does this mean anything different now?

I am not uber tech savvy and this has my head spinning. LOL

Thanks for all the help so far.

Weird as this sounds, trouble shooting stuff can be fun. I am learning so new things here

maybe ,  but still reading  wrong amount of chips. 

pull a good board  get back  with numbers with  that low freq. setting.


there is a smaller chance this is a psu issue and not a board issue.

once you give me the two board 500 freq result

 I can do one more test.  to fully decide the board or the psu.

It is not the controller   the tests pretty much eliminated that.

This morning now I cannot even get the red light near the eth plug to turn off

I will send a pic of any results once I get that sorted out now. Not sure why this happened

Machine was not running all night

Hello

Ok here is a pic of one good board plugged into controller board and the bad board in question plugged into the controller board

Set at freq 500    fan speed 30%

looks be be a bad board    mine with two for now  with a slight under clock.

say 675  to make life easy on the good boards.  Set fan at 30 or 35%


and look to see if you can find a good board or check that repair link.

Will do

Thanks for all the help.  Any idea on a rough cost of a new board? Weird how a board can go just like that.


I have looked into the repair link. Almost seems like open heart surgery on the miner

Yes I will be out of warranty now as well. I swear they build this stuff to break after 91 to 120 days

Any luck?

If the hash speed is still not up to the full speed, your unit or hash PCB or control PCB needs some repair work done to get it back to full speed.
