Best Hashboard Testers for S19Pro Issues

Hey everyone, I got some S19Pro units that are acting up. Some have temp sensor issues, and others just won’t recognize the ASIC chips. I'm thinking of getting a tester to figure out what’s wrong. I've seen options like picoBT, k8, k9, and some stuff from zeus. Any recommendations on what’s worth buying? Thanks a lot!

I bought a universal fixture from zeusbtc for my S19 XP HYD but ran into a snag. I can't seem to trace over 180 ASICs, even on a working hashboard. Now I'm curious if there’s a better alternative out there.

PicoBT is pricey but it does support a bunch of brands like Whatsminer and Innosilicon. If you’re working with different models, it might be worth it. Otherwise, the Antminer universal test fixture is solid. Go for the upgraded version, it’s a bit more than the older one but cheaper than pico.

What’s the difference between picoBT and K9 from Thanos? They look identical and claim to do the same stuff. Curious if anyone knows.

Honestly, I don’t get why they call it K9 either. They seem to operate the same and support a bunch of ASIC brands. The latest picoBT looks just like the K9, just the previous version had limited slots.
