Spondoolies SP20 Speed Help

[tomsanders]

Hey All.

Recently purchased 60 SP20 machines. Have them all setup and running but only seem to get 1500-1630 G'hs, Does anyone have any information as to get a better hash rate by tweeking the settings? Just for anyones information the intake at the from goes from 21-23 degrees and fan speed on full.

Any help would be great

Your probably hitting the max speed for the ambient temps before the chips start slowing down due to overheating.

Check the Asic stats tab and the temps like this: 85c (125c)

125c is the max before they throttle.

What is the maximum wattage you have set in each loop field? It should be 288W for maximum hashrate.  Also, you might try setting your starting voltage higher to allow it to throttle up a little easier?  I'm not sure I'd be interested in running them at higher speeds then that though, my sweet spot for my small farm has been in the 1480-1550 GH/s area, and even that was running them pretty heavy.  The advertised hashrate on them (1.7 TH/s) is not the same as Bitmain's advertised ratings.  It's not the easy-going "factory longevity" setting, it's full over-clock.
