# 0: pattern test
# 1: only find asic

Great that you chimed in, what does the pattern test actually do aside from counting chips?

The "only find asic" just does the count, no hashing. The "pattern test" runs all the chips at the frequency & voltage specified in the Config.ini file, and checks the results. If a chip is able to communicate but performs poorly or not at all at the frequency & voltage being run, this test finds it.

Generally the term 'cold solder (joint)' refers to a bad connection caused from insufficient heat being applied. It results in a grainy looking solder joint with metal crystals in it. Mechanically weak and prone to cracking causing at best a higher than normal resistance through the joint and often intermittent connections.

-First symptom was "0 Asic found". I repaired a few cold solder joints. ( I measured CLK pins with an oscilloscope )
-After repair Test Fixture found 65 ASIC chips, but then showed the problem with thermal sensors.
-Then i found on 1 ASIC chip only 1,3Volts on pins(CO-RI-RST), another cold solder, problem with 1V8 power supply line.
-Then i found bad resistance among 1V8 power supply lines. I measured the first and the last ASIC chip in the line (5-Asics in line). Resistance was 2-3 Ohms but must be 0-Ohms. -> Another cold solder

Would you explain more about "cold solder" did you find some solder balls shorting some legs/pins? it would be great if you could share some more info (photos would be really nice).

What firmware is installed on this machine? can you test with custom firmware like Vnish or BO+ ? I prefer the former, you can get it on Asic.to or AwoesomeMiner website (both have some fees 2-3%), these custom firmware "ignore" some things that the stock does not, there is a good chance that the miner might work with custom firmware.

You can run the board on the test fixture with some heatsinks off if you either shut it down before the pattern-test begins or set the option in the Config.ini file on the sdcard to only run the "find asic" test. It only uses a lot of power when doing the pattern test, so the chips won't overheat without a heatsink if only doing the asic count.

Code:

# 0: pattern test
# 1: only find asic
Only_find_ASIC=1

All of the temp sensor issues I have seen so far have been due to low 1.8V at the temp sensor. Typically you can find the 1.8V issues by tracing the resistance through the chips, like you described. Unfortunately, bad solder joints can break contact or make contact based on temperature, so many times you need to power the board up in order to find the issue. I check these by running the board and measuring the voltage drop across each chip. Anything above a couple mV drop is a potential issue. If you have access to a good benchtop multimeter, it can help a lot.

This is a lot easier with the Asic.repair test fixture, with the standard Bitmain style fixture it tries to find the chips 3 times and then stops, so you get only 15 seconds or so to measure before you have to wait for another run.

Thank you for info. But i think this issue is hard to repair. How to find bad ASIC chip without dismount all heat sinks ?

There are test points (CLK-CO-RI-BO-RST) which you can use to test the chip without having to remove the heatsinks, this is the repair manual for the S17+, the same website is also full of other tutorials, one thing to keep in mind is that if you are using the fixture tool you must NOT use an external PSU to test the hash boards.

-I changed All Thermal sensors and Asic chips connected to the sensors

But problem still persists.

Thanks.

Hello,

I am trying repair my S17+ Hash Board. I have a problem with temperature sensors. I changed all 4 sensors from NTC218 to TMP451 and ASIC chip connected to temp sensors, but same error. Can you please help me with this? Here is log from antminer fixture tester.

I did conduct long research on this problem a year ago, more details can be found here, long story short, the temp sensor error is very rarely the result of a bad temp sensor, which makes perfect sense because what are the odds of 4 temp sensors falling at the same time? slim to nothing if you ask me.

Your problem is a bad chip (or a few of them), we do not "yet" know why some chip failure causes the miner to report a dead temp sensor but we are certain that is the case, if the fixture tool did not help with identifying the exact chip, you will need to manually measure the volage/resistance across all chips.

If the temp-sensor error shows on all three boards (you get a total of 12 temp sensor errors) then that is just a bad PSU.

Maybe are some TF or RF pins shorted inside of ASIC chip and sent wrong information to the control board. (This is only theory)
Could you please share with me some experiences from your repairs?

Thank you.

Yes please.
I repaired few S17+,T17, Avalon miners, APW9+ PSU,...
But,
I have a problem to understand this error.

Thanks.

Please edit that from being a Quote to using the Code tag instead - it is the # icon right next to the Quote icon... The Code tag will change that from being a text wall to a much more readable scroll box.

Done, sir.
Thanks for recommendation.

And for doing that simple thing - you get your 1st Merit

Now you just need for someone to give you some help (I run Canaan's miners, not Bitmain ones)
Cheers!
