Hi i just got my BFL Single and it runs fine at 826Mhps. But from time to time it drops down sometimes below 700 and then crawles back up to 826. Is that normal? Also do you think v1.3 could help.

Because of the way the BFL FPGA devices work some hashes are wasted at every block change. This is why they are useless on p2pool which has block changes every 10 seconds.

Some miners may show a steady hash rate, counting the actual hashes being processed by the unit. I decided to show the effective hash rate instead because it is what really matters and it shows you what is going on. Thrown away hashes are not useful.

In the same vein the BitMinter pool hash rate is the effective hash rate. Many pools count rejected proofs of work for their hash rate, but I don't see the point in this, except that it makes their pools look faster.

I believe I read somewhere that the future ASIC units from BFL will work on p2pool. I assume that means they will have a better protocol for communication between PC and mining device, hopefully resulting in no wasted hashes and perhaps also lower CPU usage (using something smarter than polling).
