Which pool?

Try btcguild.

Anyone have any idea as to why my S2 is reporting zero as the BestShare?

Received the miner last night.  Usual case of boards all over the place.  Pulled everything out.  Checked all cables.  Reseated all boards.  Fired it up and configured it.  It's been hashing perfectly all night.  Right around the 1000GH/s mark, 53C, posting shares to BTCGuild as would be expected.  Just zero BestShare value.  Not that I'm concerned about this.  I'm getting paid for the shares I am submitting.  Just curious.

Thanks!

My 23 day uptime S2 is best share 0, its just not coded.

Funny enough, my partially busted S2 shows great share=~400000 in one hour (since last reboot). Too bad it doesn't mean anything.
Dogie-is it theoretically possible that one slot not hashing could be remedied by the software update? Since there is an obvious difference in how it handles best share, maybe there is a software glitch? Did you ever had a situation when asic non-hashing was fixed by the latest software update?

I have a best share value of 461 after only 30 mins of hashing.

Nope, mine's batch 2. I've just reconfigured something and restarted so it's only been up for 30 mins.
