Still waiting on two more batch 1 orders dated 9/04 and 9/15.

Also have a pre 8/31 unit which stopped hashing at optimum (dropped by 1/3) after 10 days online. Hard and and soft reboots with not change. Appreciate some assistance on warranty service, Bitmain. Reference your support ticket #4143.

Do you know which board? Sounds like a board if it is one third. You can see a little red light on the hashboard near the connectors.
If no red light then...
You can detach hash cables one at a time to find the offending board.
Sometimes dropping the frequency will pop it up.

Have one s7, lots of time with other bitmain products.

Thnx for the reply, wolfen. Same here. I've been an infrequent poster but have been running equip since the GPU days. Moved through ASICMiner block erupters, Bitfury/MBP units and a few BFL units; and now solely running Bitmain equipment. The problem seems to be the chain 1 board. Yes, there are red lights on all three boards.

The pic below shows the chip failures on the board. Interesting to note... I have yet to see the chip failures displayed again on the web page. Hard, soft reboots and freq changes - still o's. The chips show o's every time I check the page. Something's definitely amiss.. Thoughts?

This must be what they saw when they shut everything down.
