Hello all, I am pool mining Zetacoin (alt coin, but still SHA256 based) at the moment, but my results have been the same with mining for BTC with BitMinter.  It seems that my video card that mines at 75Kh/s mines WAY MORE efficiently than three ASIC block erupters with a combined hashing power of 1.1Gh/s.  At first I thought that this might be the hardware, or the version of cgminer I was running, etc.  But I have moved these around to different hardware and the result is the same.  I have also gone between cgminer and bfgminer.  No difference.

Here is a screenshot.  Note the speed - and the number of accepted shares.  Am I missing something?  Perhaps I am not reading the stats correctly.  Or is there something I need to tweak to make my erupters mine better?

get the newest cgminer v3.4

Instead of showing total shares it counts the difficulty of the share. So like im mining on middlecoin pool that has a static difficulty of 512, so every share my accepted goes up by 512. This should give you a way better idea of whats more efficient.

OKAY!  After a bit of kicking and screaming from my hardware - I am running 3.4 now.  I still don't know what any of these stats mean.  Good time to RTFM.  ;-)


And what does that mean exactly?  *fumbles through the README*
Each column is as follows:
5s:  A 5 second exponentially decaying average hash rate
avg: An all time average hash rate
A:  The total difficulty of Accepted shares
R:  The total difficulty of Rejected shares
HW:  The number of HardWare errors
WU:  The Work Utility defined as the number of diff1 shares work / minute

Aha!  So, yes.  This makes sense.  And now I can see that while this video card is cracking through Accepted messages like mad - it's still not doing anything notable, as suggested by the WU:0.0/m tally.  I would have to break that down differently before it registered a value!  :-)

Thanks for the help gentlemen!

And here is a screenshot of the same hardware running 3.4, just because.
