I got my two ant miner S3's yesterday.  Batch 3.  They run ok, a little sporadically from high 300's to 450 Ghs.  Both stock clocks.

How do I tell what version of the firmware I have?  I've looked everywhere in the antminer control panel; must be missing something, but the current version on Bitmain's site is antMiner_S320140721.bin.  Is there an easy way to see if I already have that or should upgrade.  (I would like to get rid of the sporadic beeps every ten minutes or so!)

Thanks!
