I tried to do a DC amperage measurement, but my hall-effect clamp meter is broken.



By the way, if you're curious in purchasing one of these units, you can see my auction here:

Hello all, I would like to report, for prosperity and comparison, that my BFL singles get 4.3 J/GH with stock firmware using a LEPA G1600 ATX PSU. With this particular power supply, PF was 1.00 within measurement error.I tried to do a DC amperage measurement, but my hall-effect clamp meter is broken.By the way, if you're curious in purchasing one of these units, you can see my auction here: https://bitcointalk.org/index.php?topic=249575

I could, but it would be awfully boring: the kill-a-watt changed by less than 1% while running (I assume because of heating and therefore increased omhic resistance). I believe the 10% variance is with respect to unit-to-unit variance, not within the same unit. Also, the hashing variance was really low, all three are pretty much locked onto 60.2 +/- 0.6 GH/s. I believe this is because the number of diff1 shares returned to cgminer was very large, leading to small variance.

Good to know my spidey senses were dead on yesterday though.



Good luck sir and happy hashing! OH jeez. I can't believe it pooped out on your so fast, sorry to hear that. I'm sure BFL will replace it, as their equipment is under warranty.Good to know my spidey senses were dead on yesterday though.Good luck sir and happy hashing!
