You can run it off any PC, and that's preferable anyway since the RPi is a piece of shit. Just plug in a USB cable. The sierras don't even have one so you have to run them via USB. Any instability still around is firmware related and remember it's still early days since release (even though release was late) but once my sierra is running it does not miss a beat.

Mine is happily hashing from an old mini PC desktop. Will try to resolve a driver conflict with Karin's help and get it hashing on the Mac mini later today.

Interestingly, after running overnight, this BJ seems a little off-spec. It's doing about 395-7 g/hash (running cgminer 3.11).

OTOH, my HW error rate is very low and with an ambient temp of 21c (70f) my processor temp is 69-70c. What did other people get for out of the box processor temps?

I guess I should experiment with overclocking next... I've seen 610 mentioned... other suggestions?

And sorry ckolivas, I didn't mean to suggest the Mac driver issue was your problem. It was intended merely as an observation.

And finally... why don't we try to move all this operational discussion over the the user's thread? I would still like a thread more focused on the company and its operations (and interesting cast of characters), like this one was before HF really started shipping.

In fact, I'm going to xpost over there.

610 is good but you might void your warranty by doing this FYI and with any ocing you risk damaging the hw. So do this at your own risk.. Sorry needed to add this disclaimer.

Overclocking is the ONLY way you can even hit their promised performance!

If you clock to 610, cgminer will show it runnign at about 450 GH/s. But we know now this is not the REAL hashrate. Eligius will show it running at 425 GH/s. Why? Because cgminer is currently incorrectly counting bad shares (unless you upgrade to 3.11).

Upgrade cgminer to 3.11 and you'll see the hashrate drop to 425, the REAL HASHRATE.

Now, put the settings back to stock (clock 550), cgminer will show 420 GH/s but the real hashrate will be <395 GH/s. Not even the 400 GH/s we were promised.

Once again HashFast has over-promised and under-delivered.

btw, the BJs are not very overclockable. You probably won't be able to go higher than 615 clock without crashes every 30 seconds. I was hoping the BJs would be overclockable to at least 500 GH/s but now it looks like not even 450 GH/s is possible and overclocking is necessary just to hit 400 GH/s.
