I mean, he’s selling silver! Of course, he’s gonna trash Bitcoin. Makes total sense from a business perspective. We just need to see through that.

Risk management isn’t rocket science. Don’t invest everything at once! The goal is to not lose it all. If you keep losing, it’s time to rethink your whole approach.

Meantime I've been watching the logs on this T17 and noticed that board 1 will occasionally throw this error: Looks like the chip after 14 is having an intermittent connection. Great, I love intermittent connections. So…

In the meantime, I’ve noticed that one board throws an intermittent connection error. Took out the board, examined the chip pads, and found some junk on them. After a reflow, the pads look much better.

Yay! I’m helping save the planet by making miners more efficient! When I get my Nobel Prize, I’ll definitely mention this forum...

If you mean those boards with a single Vcore, I’ve said this before. Using the PSU for all the regulation saves a lot of efficiency. It’s why modern miners are doing so well.

I’ve got six S17 Pros hooked up to Braains. I’ll test the voltage change soon. Set freq 400 at 17 volts was doing 37.5Th at 1434W, now it’s 38.1Th at 1310W with a nice temp drop!

Wondering if all boards are getting the same volts? Maybe you can set frequencies differently for each board based on performance? I have an S17 that can’t auto-tune because one board overheats.

One more thing, about auto-tuning. Braains loves to auto-tune, but it doesn’t always do a great job. Boards can get shut down while it tries to mess with voltage and frequency. I prefer to turn that off and stick with…

Nice job! I just got a T17+ back up and running at about 45Th. I’ll share how it went down. Had a situation where two boards were cycling between zero and hashing, while the third was completely dead with only 33 dies…

I just removed some heatsinks using hot air at 360C without preheating. They came off pretty easily, and the solder layer is thin. You can reattach them at around 300C with a bit of flux.

Right? The solder does soften up sometimes. Had a few boards where the issue wasn’t a bad chip, but just some extruded solder balls getting in the way. Did the heatsinks just pop off, or were the chips affected too?

So, first tip: don't ship these boards casually, okay? The design for S17 and S19 is a bit more fragile than the older S7/S9 models. The heat sinks are huge and only supported in the middle. If you press on them or if…

Hey everyone! So, I've been getting a lot of T17s and other miners sent my way. Figured it's time to kick off a new thread for all of us dealing with these machines. Sometimes I even get asked about fixing KNC Neptunes,…

I’ll get into it by next weekend. One’s coming in on Ebay by Wednesday.

FTFY and good vibes to you!

It should arrive by Wed/Thu, and I’m planning to open it up since no one else is doing that right now!

Guess what, I officially own a BFL 700gh Monarch just bought it for a cool $1k in Bitcoin. Woohoo!

Mr. Teal, are you considering making your own board for these chips, like the habanero?
