Got my S5 almost 2 weeks ago now & finished the last setup & mod task last night. Thought it would be good to share all the details here, both for those who are new to hardware mining & in case someone with more experience has a tip about something I missed. Here's the state of the project this morning:
Is that psychedelic or what?
Power source is a 1000W Seasonic Gold PSU that I picked up at Amazon for $150. Yes, there are cheaper PSU's but I learned the value of clean power a long time ago & would never use something less than Gold. Almost got a 660W Platinum Seasonic, but wanted the ability to overclock & there might not be enough juice for a good pop up. Base wattage of the S5 running at default 350 MHZ is about 600W.
First thing I did was set it all up, turn it on and point it at BTC Guild, a nice stable pool with good I/O. Only downside there is it's relatively small and subject to big swings in luck. Everything ran great at first, but the S5 fan is one of the loudest ever, with really nasty dissonant harmonics. Taking the finger screen off didn't help much. New fans ahoy!
I also found that every time I used the remote interface it would somehow screw up the Hashrate. My unit came with a mid-December firmware version and upgrading to the Jan 7 firmware solved that problem. Upgrading was simple, you just download the tar.gz file from Bitmain & use the interface to import it; no need to open the archive. Be sure to back up your setup before you upgrade, just in case!
At this stage of the process I had a miner that was hashing at a steady, stable rate.
Next Up: New Fans.
