Bitcoin / Hardware / Re: Unofficial Spondoolies SP20 thread

Quote from: Digitalmocking on March 05, 2015, 04:16:55 PM Quote from: obfuscated on March 05, 2015, 04:11:26 PM I'm curious what pool configuration people are using. Currently I just use westhash: Is there a way to optimize this? For example; is it possible to set a fail-over pool if there is an issue with westhash? Or to switch pools if another pool is currently more profitable? I know you can set parameters in the password field but I'm not sure how to use this. Absolutely there is. I mine at kano's pool but I have westhash and nicehash set up if the rate is high enough to make pool jumping worth it, then I have two other backups just in case. "Stratum+tcp://" what does having this at the beginning of the server address do?

Quote from: alh on March 04, 2015, 05:58:16 PM Quote from: thedonger on March 04, 2015, 05:14:38 PM So I'm a little new at this, have my first SP20 running almost a week now (took most of that week to read all of this thread ). I had one of my New CX750M's die (sending it back for exchange), so in the mean time trying to set things in the safe zone with only 1 PSU with 750. I need some input from the pros to know if I'm in the zone.

That puts you at 96% of the power supply rating. I would step down another 15W per loop and give yourself some more margin on the power supply. Yes, you'll probably lose some hashrate in doing so, and get a bit more peace of mind. Just my $.02. Ok reduced to 165 each loop, after 40 min steady at 1212 Ghs with ASIC reporting 647 watts total. Temps are good but all 4 loops are reporting slight under power but not affecting restart so far.
