Hi All. I need some help here:

Just got hold of a Spondoolies Tech SP20 yesterday. Last night I set it up and it seems to be online now. Aside from some RockBox miners, this is my first BIG miner.

The SP20 itself reports it is mining at 1.3 TH/s. It's fan sounds like a vaccumm cleaner. Every 20 - 40 minutes the fans die down and start back up again. I'm not sure why.

What's odd is that on my pool account page this miner is reported as contributing very little to the pool. On BTC-Guild it was showing 4 GH/s and on Ghash.io it is 15 - 40 GH/s. All this time the SP20 is reporting 1.3 TH/s.

This is supposed to be a 1.7 TH/s machine! What gives? Have I missed a critical step?

One thing I've noticed is that there are difficulty settings for each pool. When I change these and wait a while, I don't see any change in GH/s reported on the pool.

Any help is appreciated! I'll also see what I can do about posting photos. I took a bunch when I had to open the thing up because the PCBs inside were misaligned with the internal chassis mount points.
