202GH/s
@ 400MHz / 204GH/s the hw error % is 63,253/(63,253 + 3,543,296 + 41,984)% = ~1.7%, which is rather fine for a system operating at its limits
Kudos to Bitmain engineers.

Kudos to Bitmain engineers.I have a question about how multiple pools are handled.
Are pool 2 and 3 just backup pools in the event the miner can't connect to pool 1?
I think so the default is failover. Are pool 2 and 3 just backup pools in the event the miner can't connect to pool 1?

How to overclock your miner to 400MHz / 205GH/s. My suggestion is to clock them at 375. 400 is a bit too harsh on the voltage regulator.
All clock speeds including 375MHz work on both revision of boards.
The miner will draw 500 - 525Watts at the wall (110V mains) after this setting
A) ssh into your miner
B) edit the following file
/etc/config/asic-freq
C) change timeout to 36, freq_value to '0780', 'chip_freq' to 400.
For miners with build date 2013/11/4
For miners with build date 2013/11/18
