Thx for the links guys.

Lots of Communication errors in cgminer display
Looks like it is just more/different reported noise.
NOT detrimental to GH compared to rc6.

I'll let er soak for 12 hours and will return with avg and pool results.

I use 3.6T as perfect and compare to it BTW (for 7200 @ 500MHz)
It is the current bar AFIK

rc6 had around 2% of where did it go??? was not reported in HW errors.
HW error has increased from 0.18 to 0.8%
What I expected with stock voltages on everything.
(28nm as my expectation reference)
Treat them individually and they more productive.

CPU load  is around 25% now as opposed to 100%

Positive overall experience with FW 1.0 upgrade here.
It has what we seek, a few more GH.

EDIT
If ya do heat a VRM till he goes on strike,
no need to power cycle for negotiations to return to work.
The Advanced page works great now.
Excluding the limited clocks

YMMV
