Title: Antminer S3 ASIC issues
Post by: BigFun on January 01, 2016, 09:01:17 AM
Hello fellow miners!

I'm a neophyte to this hobby but am a quick learner.  Need a bit of help please.  I bought two used S3+'s and both of them have all of the ASICs on chain one disabled.  Is this normal for this model, I don't think so.  Thoughts?

No it is not normal. Did you power both blades? All 4 PCI-e connector?

Since both of them are having the same problem, my best guess if you plugged only 2 PCI-e of one board and the 2 PCI-e of the other boards unplugged.

That fixed it on both units, thank you for taking your time to respond to my post.

I plugged in all four 6-pin connectors and all ASICs were happy.  Weird, I thought you were supposed to be able to just plug in two per S3 (if not overclocking) but whatever works.
