Antminer S17 Hashboard Repair: Voltage Testing Basics
HTML-код
- Опубликовано: 8 сен 2024
- Learn how to troubleshoot an Antminer S17 hashboard by performing live voltage tests. Watch as I walk you through the general layout of the hashboard, including power distribution, signal flow paths, and expected voltages. You will also get a close up view as I use the Zeus Test Fixture to obtain live voltage readings from various points around the board. Learning these basics is a necessity when troubleshooting most boards.

he strikes again! Top quality. A gift to the community. Thank you Steve!
My pleasure!!
Best explained video online
Thanks Kian! Glad you think so.
Hi, thanks for this video. The best on youtube. So simple, well organized information and clear. I was searching antminer repair videos for months, but from yours, i could understand in 10 minutes about the basic signal lines, how to diagnose them, and i repaired the first S17 Pro board. Please keep up making more good videos.
Greetings from Romania
I'm glad I could help you. Thank you for the wonderful feedback!
Excellent learning course.
Good and clear videos! I suggest you doing one showing your setup for the tests, all the tools you use and the ones your recommend!
Perfect! Thanks!
That is really great! So skillful guidance!!! Thank you for your contribution to our knowledge!!!!
Really good content with detailed explanation. KEEP IT UP YO !!!
Really clean and clear.
Thanks! This is very clear and useful.
Another fantastic clinic on S17 repair. You definitely have a true gift as an educator if the mining gig goes to the opposite of the moon! Bitmain should have a link to your channel well have you on the payroll to boot.
Have you ever seen a board pass every signal but still show partial ASIC's? If so would changing the chip after the last good one be the next step or the last good chip?
EDIT: Capacitors!
Haha, thanks Chris! If there are any Bitmain folks out there, hook me up.
I don't think I have had the entire board pass, however I have definitely had issues where the number of good ASICs was not problem. Instead the the adjacent one in a different voltage domain was causing the problem.
Great information and added to my knowledge as I prepare to troubleshoot a few S17 hash boards! Still unsure what is the status of the Zeus tester before we start though….
Hey Paul. I'm not quite sure what your question is. Are you familiar with the Zeus Test Fixture?
Wow fantastically done! Can you make a same video with an absent 1,8 volt RO signal. Meaning that RO signal is completely absent from te beginning of chip 48.
I have one board like that but I'm saving it for later. I'll try to share with the community when I work on it.
Glad to see you back. Does this also apply to the S17+?
Yeah, sorry the delay!
OMG 100000 BEST THAT BITMAINS TRAINING, make a course and sell it pls
Thank you!
My hashboard RI signal into chip 48 is zero, where does the RI signal originate since there is no chip higher than 48? Excellent video. Well explained with great pics
Sorry Robert, I have 2 boards with the same problem but I haven't taken the time to research the solution. Please let me know if you do figure it out though.
Yea same problem… wish you would have shown how to fix or war to check if you have problem at step 1…..
Let me know if you're willing to provide training. I have 10 AntMiner S17+ machines with a variety of card issues. Core Scientific said they were un-repairable. I would love to see if I can get at least a couple of them working again.
Nice
Good
Dumb question, when you were testing the voltages on the board was it hocked up to Zeus Test Fixture and PSU? I got a S17 Pro showing 24 out of 48 chips found and checked everything in the previous board video and couldn't find the issue. any ideas? Thanks.
Yes I'm connected to the test fixture and use the APW9 PSU. I would start pulling heat sinks around 24 & 25. Do a close visual inspection and double check readings. If still nothing, reflow 25 and maybe reflow 24.
👍
Do you provide training courses?
hello, do you repair the s17+?
I meant, if you have the service to repair them...
Sorry I don't repair anything beyond my own S17s.
hello, what do you recommend to mark the hash board? It is so that they are not confused with other people hash boards. the issue is that my customer needs the mark not to be erased with the cleaning maintenance, he thinks his hash boards are being changed. Thank you
Hey Ramon. I write a number on the first silver pad to the left of the positive terminal. I use a "Sharpie Industrial" permanent marker which claims to have "super permanent ink" that is resistant to oils, chemical washes, heat and steam. It fades slightly after ultrasonic cleaning however it is still very legible. If you want something more permanent I would suggest etching something on a blank spot of the board or use an engraver on one of the silver power pads near the top. Hope this helps.
Thank you!!, I appreciate it.
to do your voltage test do you have to press the green test button everytime??? or just put voltage on the board??/ that tester give me 0 asics even if Ive got a working boaard///...hate it..
Yes you hit the button each time. It only pulses the board for a short duration, allowing you to get your reading. If you have a working board, why are you testing it?
Other testers will allow you to run the power through the board for longer periods of time. I've also seen other techs that will place the +20V clip on the other side of the mosfet in order to test voltages. I have not tried this myself since my tester allows for a longer test cycle.
Hi, do you have the Bin file to be load with code editor, for S17 pro?
I have one machine with all 3 hasboards with wrong code.
Thanks
You still need this?
Hi, is possible to make this without test fixture?
Hello Jorge, it can probably be done without the test fixture but I imagine it would be very difficult and possibly unsafe.
Hello,
i have a RO of 0.003V this should be exactly 0.001v?
and can i ask if some one have an idea why is 0.003v?
Thank you
RO should be 1.80V
Buenas, tendra alguna red de comunicacion, donde podria hacerle una consulta

Can you show S17+
Sorry, I do not have any S17+ boards to work on.
Thank you for the reply.. i got a question why does the diode resistance goes high like 1450 for the 4 signal after changing to new chip.. i know that it should be 1200+-.
I've had so much inconsistency when performing those checks, I stopped doing them all together
L3 are s9 please
Sorry I don't have any experience on those boards.
لطفا هشبرد t17 42 را اموزش بده
🙏
Sorry I haven't worked on any T17s
Wow fantastically done! Can you make a same video with an absent 1,8 volt RO signal. Meaning that RO signal is completely absent from te beginning of chip 48.
Thank you! I have 2 boards in my repair stack that are missing this signal. That is going to take some digging into so they are set aside for the time being. I'll be sure to pass on my findings when I do.
