1  Bitcoin / Mining support / Re: Bitcrane T-110 miners - using damaged miners to build into working miners on: December 05, 2017, 02:52:47 PM
Glad to see this (and Dogie's) thread so I don't have to necrobump anything.
I'm in a very similar situation, as I wanna get a bunch of old T-110 units I have lying around working.
Kinda silly, sure, but if people are selling 333mhz block erupters for $100 as "Collectables" then I can try bringing life into these old boards.

The problem I had was the web interface wouldn't initialise cards, if they would it wouldn't be for very long.
I have (had) 4 T-110's, between them two of 8 UltraHoist boards work fine.
I've torn them all apart, and have the two working boards churning away currently (Hooked up to a Pi manually running cgminer)
As for the other 6 boards, two have corrosion damage so I'll save them for last, but the remaining four all have the same problem: I'll run cgminer, they'll WORK, but rapidly hit the 96c thermal throttle, then the 100+ thermal shutdown (Maybe withing 5 seconds of starting?), then reboot and start again.
At first I thought it was the thermal paste, but after re-applying it there was no difference, messing around with HCM told me that all the die's are at the same temp (couldn't get the original tool at https://github.com/BitCrane/cgminer to compile, I'll mention HCM later), so it's not uneven paste, finally I removed the watercooler unit and found the pump clogged up with white gunk, something I usually find in AIO coolers after three or so years of heavy use, quite normal.

(Dogie mentioned dying PSU's in his thread, I've been testing the boards between PSU's, and a bad board will be bad no matter the PSU, same goes for good, so I doubt they're any problem)

I could test by putting one of the good coolers onto a "Bad" board, or vise versa, but I've ordered a few fans and an AIO kit just to see if they help, not wanting to do anything at all to a board if it's working as is.

The other issue I've ran into with all this is that the boards are set to run at 0.82v, even one that looked like it was factory sealed to an extent.
HCM compiled for my Pi isn't able to set anything, and trying to set a default voltage or clock speed just returns the same output as reading the existing settings from the board without modifying anything.
Trying to run it on the cubieboards is futile, as they try running cgminer no matter what, and will respawn them if you try closing the processes.
I've even removed the cgminer binary, no difference, "Device busy"
Next I'll try flashing the boards using a config file like the manual describes, but first I'm downloading a new image for the cubieboard, as the home folder of the one I was using was littered with programs and files (possibly from a past user, possibly from bitcrane. The downloaded image should tell us).

I'll also try using the x86 version of HCM they provide once I can grab a x86 linux box, and see if that helps at all.


Not sure if this'll help anyone, but this is just the troubleshooting I've done with my boards so far.
CHECK THEM WATER COOLERS AND TEMPS IN CGMINER
