I just received new firmware from Dominique @ Innosillicon.  V1.0.3

https://www.dropbox.com/s/fuyz1r7cy4pkeir/G5-20-V1.0.3.rar?dl=0

I am testing now.  

To be honest I have had no troubles with version 1.0.0(T) as long as the machines run in a cold environment.

If anyone is interested I have had them on MRR for the past couple days so you can see my hash rate here:   http://rig.rent/rigs/34677

Update:  2hrs hashing with new firmware on half my units.  No dropped cards or cgminer restarts
