Dogie, is 1250 GH/s reported on BTCGuild (1320 GH/s avg on the miners) @ 25C normal for us 120v users? One of them is only hovering around 1305 (1215 on BTCGuild).
I'm kinda disappointed at these numbers. These are expensive units and makes a lot of noise. Was willing to put up with it if I could get 1.4 TH. I didn't know they had to limit it. Should have advertised as 1.3 TH to 1.4 TH. Can't help but feel a bit cheated/baited.
Ignore btcguild, pool hash rates are always variable. It depends what clock rate you're in, if you haven't looked in detail then you've still got the 120V FCC cap on. You need to remove that to remove the cap of power consumption which will allow your unit to hit the higher clock modes.
The numbers shown in miner are usually 1-3% higher then the pool. That is because of the HW errors and discarded shares.
HW errors more common when miner starts (first 30 minutes) and can be up to 3%, but after a while usually around 1%. Discarded shares usually around 0.5%.
