Fewer errors for the most part, and more reliable. Some of those s9's are horrific on their reliability.
And others refuse to die. Still have my only Batch-1 and 3x batch-3's along with a slew of others up to batch-25. When BM stopped accepting
BTC I moved to Avalons and have not looked back since.
Think the earliest s9 that has had even a fan die is a batch-9. After that batch- several hash board faliures and 2 fans, etc. Probably 1/2 of the s9's I have after batch 11 have been retired and replaced with the Avalons, the others get doner boards and controllers from the retired ones as-needed.
As for
Somehow I've been around for half a year and am just hearing that Antminers don't need a RPi to control it... Mind = Boom
That is/was their only nice thing. Pure plug&Play aside from just needing to enter user & pool info. However BM software is not exactly Open Source. Ja it *is* out there but...
That's funny...I never noticed before but batch 9 is where my S9 problems started. I have a couple of earlier batches that are still running fine but from batch 9 on I've had all kinds of problems. I have 2 of the 13.5TH/s models from February that are giving me problems now.
I'm so glad that I started buying 841s after that...I have a couple of 721s and I should have stuck to Avalon's from that point.
