Lightman: Glad you got your new gear! Looks like it's running really nice for ya..

You can go a little higher on your IMC volts if you need too, as long as load temps stay around 53c (at least that was the temp stability zone on 965's).

Anything up to 1.3 should be fine for 24/7 clocks, and some folks push all the way up to 1.5.
I ussually just take small steps up in V's until I see deminishing returns...
