updated thanks

I have 4 Block erupter cubes all work perfectly, 3 will run on high clocks but 1 wont run on high consistently. I have 2 corsair cx750 PSU's to go with them that will each run 2 cubes

so all 4 im looking for BTC0.85

for one that will run on high BTC0.25

the one that will run on low BTC0.22

power supplies are BTC0.1 each

shipping depends on to where but north america would be BTC0.04 a cube or BTC0.12 for everything

sorry for the bad pic

so i have 4 cubes, everything runs fine until after about an hour one of the cubes just randomly stops mining, but once i cycle the power it starts again and is good for about another hour, all 4 cubes have identical settings and they all have plenty of power. any ideas?

i have a question, so after hours of fiddling around i finally got one of my cubes to work, now under low clocks my efficiency is about 90% but when i switch to high clocks it drops to like 60% any ideas?


thanks
