Re: ANTMINER S3 Discussion and Support Thread.

So I have my S3+'s up and running, but I'm trying to overclock them to 237.5MHz. But they get a lot of hardware errors (sometimes up to 5%), and sometimes the chips starts showing x's.
Is there anything to solve this? I guess the S3+ from B8 are installed with latest firmware?

Also, I don't really know what pool to choose, currently mining on Eligius/Discus Fish. any suggestions?

As the product info on Bitmain's own page says, not all S3s will got to 500, so no, not really any way to solve it.
As Blizzard would say, "Working as intended".

Quote from: Bitmain

Bitmain now announce the S3+, which is a revised version of S3 running stably at 453GH/s (frequency=225 MHz), while consumes 355 Watt power at the wall. Most of miners will be able to run up to 500GH/s but not guaranteed.

(Emphasis mine)

Okay, but what about the chips that fail? I can't restart the miner like every hour or so?...

Getting an x on chips only when you clock it up is symptomatic with the issues that caused them to clock them down to 225 MHz. If you have issues at 225 MHz, RMA with Bitmain. If you have no issues at 225 MHz, there's nothing wrong.

too bad, I think my miners won't hit 453GH/s at 225MHz...

They should, but if they can't, take it up with Bitmain.
