The expansion has been a bit slow. Suffered a mysterious board death when I was disassembling the pair of quad 5970 rigs. It was a R3E that had already suffered horrible corrosion damage from condensation during some GPU overclocking. Oh well, replacement board inbound.
Right now I've moved everything except my 5970s to my remote location. The GPU stack below is generating ~7.6 GH/s, pulling ~3.2kw from 3 20 amp breakers. I'll be adding 1 more rig with a pair of aircooled 5970s to bring it up to ~9 GH/s and ~4kw. Just trying to keep the load on each breaker below 15 amps for safety.
Next week, once the replacement board arrives, I'll move the last 6 watercooled 5970s and bring that location up to ~13 GH/s and ~5.5kw. That'll bring me within 10 amps of tapping out the 120v breakers so I'll have to look in to utilizing the 240v connection for the next GPU expansion.
Currently exploring various options to increase my MH/w efficiency. Considering adding 4 to 5 BFL Singles as a start. Would like a mini rig but $15k is hard to fund.
