Title: S17+ defect chip finding with ZEUS chip tester? Post by: moftkhor on June 29, 2021, 09:16:56 PM 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. Title: Re: S17+ defect chip finding with ZEUS chip tester?

Without the fan, it will automatically shut down due to overheating. Title: Re: S17+ defect chip finding with ZEUS chip tester? Post by: philipma1957 on June 29, 2021, 10:35:52 PM 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. Title: Re: S17+ defect chip finding with ZEUS chip tester?

Without the fan, it will automatically shut down due to overheating. 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... Title: Re: S17+ defect chip finding with ZEUS chip tester?

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?

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.

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... |
