Hello there,

So I have a whole bunch of pain in the ass defect S17+ hashboards.
I've been mining for years now so I got quite some equipment and tools laying around.
I also have a Zeus chip tester with the S17+ software and everything.

So I've been fooling around with it for 2 days now trying to find the defect chip.
First pain in the ass: The damn hashboards keep shutting down due to only 64 chips found (you know the regular S17+ bullcrap). This is with the Zeus tester plugged in to it. Is there any way to let the hashboard continually powered on without the automatic shut down so I get enough time to measure the chips with my volt-meter?

It's a real pain in the ass to push the test button every few seconds and wait for half a minute for the whole damn thing to power up.

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

Do you put a fan on the hashboard while running it with the test fixture or zeus tester as you call it?

Without the fan, it will automatically shut down due to overheating.

try braiins software via an sd card.

lower the freq to 50 and hit the board with a box fan airstream.

braiins has the option to drop freq to 50

and to set fans needed to zero.

Yes I have my fans directly on it. The hashboard barely warms up. It directly shuts down after it tries to restart it a few times due to the lower than 65 chips found...

I have Asic.to. I think all the same options are on there too. So I set the asic.to software on the test fixture and let it run with the fans right?

No firmware will work if all chips are not found.

Yeah, the Bitmain style testers like the Zeus tester are painfully slow for troubleshooting. I started using the Asic.Repair tester (https://tester.asic.repair/en), which will run the count test in a loop indefinitely, giving you all the time you want to probe the test points.
Have some dead Bitmain 17 series hashboards or full miners?
I'll buy them ... send me a PM with what you have and I'll make you an offer!

I saw those sell online. So these models do loop uninterrupted? I wasn't really sure so I doubted to buy one due to the higher price...
