Updated to the new firmware -- everything works great!
For people wondering when you go to update/flash the new firmware -- select the entire .tar.gz file using the webgui.
One thing I noticed is when rackmounting -- the screws for the rackmount ears stick out too much (when sliding into the rack you'll need to force it in) and sometimes the screw holes don't align with the ear bracket. You need to unscrew the top, reseat it so the holes line up, then screw the ears on.
Has anyone gotten decent results with overclocking?
I have a couple units that are only averaging 1.75TH/s on ghash, while my others get between 2.0 - 2.4 average. Any ideas on how to get the low performers up to regular hash rate?
