if you are able you should test the temps of all the components on the card during load, i have no room to work with at all and don't have a good thermometer either
I had no issues running at 1.320v, but there was no need to as I am now 100% stable at 864/2106 at 1.281v. It probably varies by card, my loaded temps at 1.320v were 33C.
