Ok, so I had three of my four B5's on 250 and they ran great but I felt like I might have been pushing my luck some so I put them on 243.75 and man, I must say, from philipma's expectations of what he said I should get. I'm doing pretty damn good.



yeah  that is pretty good .

 your 1 slow one may want 231.25  it may give you the same hash as the 237.5 gives you or it may even give you 460gh.  it will also save power over your 237.5 setting.

What I found so far is :
batch 1 sucked
batch 4 was better
batch 6 was best

I am running these in my garage  with temps about 92f in the garage.
