Thanks Gateway for the board layout pictures. That helps clear things up.

Thanks again for the technical details of your sierra.

+ 1 and thanks for the thread.

No problem.. my next task is to figure out a good way to define what is the best clock rate per box.. they are all a bit different, I'm waiting for hopefully cgminer or bfgminer to allow me to adjust the clock rate via api and would write a script that would try clock rates though a range and report the best after running for some time since it takes a good 10-20 min for a good average reading.

Also if you get these boxes I suggest you mine at the eligius pool

and if you do ever have questions about the pool or sierras im usually hanging out on the irc channel #eligius

What have you found to be a good starting point for OC and is there a point where the tradeoff for speed is drowned by the extra wattage?

How many watts can the PSU's support?

600 or 610, but OC at your own risk.. Off the top of my head I dont recall what the psu's are.. maybe 750's op 850s.. i know the jets come with 1000 watts

Here are some mining boxes pics

These are on our test bench in our server room.. finding enough power on that bench was quite a challenge

you can see on the right a jupiter with its cover off..

Back of some boxes.. 2 psu's one usb connector out per box..

Some of them in one of my racks..

Hello, Does a beagle bone black work with the Sierras?

Yes, you run Linux on it and install cgminer

Quote

If yes, what are the commands?

Is this even a serious question?

What can you tell me about the "AUX POWER" connector?
Is it the same as what you'd use for a 3.5" Floppy Drive?
I take it it's connected to the power supply - not somewhere else inside the case?
I see it's a 5 pin connector, but most of the floppy drive connectors I see are 5 pins but 4 wires; what does this one have?

Thanks for the info!

EDIT: Sorry - mine hasn't arrived, or I'd be able to see for myself.

Update..

Im able to stop and restart cgminer about 95% of the time now and the boxes come back up but I had it a few times where I would have to power cycle and unplug and start fresh again..

If your 2nd or 3rd device comes up with ZOMBIE give it a few to re-kick in..

more testing results to come.

Thanks Gateway for the board layout pictures. That helps clear things up.

I haven't done much exploration of my BJ1 units other than to get them mining, and experiment with different external fan arrangements. I ordered some corsair i100 coolers in anticipation of the MPP. It is looking like the Seirra's seem more efficient than single BJ1s, so I may arrange my MPPs are seirras.

Thanks again for the technical details of your sierra.

What are your Jets running at temp wise? You need to only really worry if they pass 90 and at 100 the chip will shut every thing down.

Also are you using the --hfa-hash-clock (Sweet spot for most of my boards are around 600 or 610, but you need to play with each board and look after a few hours at the place your mining)

I also hang out on irc #eligius if you have any questions.

I have several arriving soon. I'm really hoping they can be hosted on one host.

Im trying cg and bfg today with more than one plugged in..

Ill be testing the following:

Starting with more than one sierra plugged in at start
Stopping the miner and restarting it (biggest issue I had)

New version of cgminer 3.12.0 I just posted has some communication improvements for usb errors that hopefully should help the reliability of these.

+1 , trying it now, I hope it can resolve the multi sierras on one box..

Hello, Is everyone who received their Sierras from batch1? Anyone in batch2?

I am in batch 2 and have not even got the confirmation mail. I don't think that they make it until 31st of january, looks more than mid-february to me.

Lets hope you get your soon but please keep this to only tech related stuff, I perfer not to turn this into a I didnt get mine thread yet.. but as I said I hope that yours arrives soon.. cheers!

gateway,

did it fix the multi sierra problem?

I'm going to test it tomorrow, I had a ton of work todo today and didn't have time to mess around with them, and I always have to walk in the server room and do my magic trick if they dont work.. more info to come...
