IT depends on your ASIC quality? Mine is 64% and It seems by reading the forum that you cant get an extra 50-70MZh max frequency with 50-75 mV less volts but all seems to wall at 1450MHz
I'd say 1300/7000 provided that case is well cooled, ( you can get your card stable for 1 hour but it is realy difficult to control this point, it's the reason why somes gets a water coolied mobo.

So either my top pci-e lane is somehow malfunctioning, or my top 780, I'm betting it's the latter.
Still befuzzled on how this happened, I never brick anything
Bah, nothing but trouble.
THe topmost may require additionnal voltage by itself due to it being less quality asic,, and if it is the case it shouldn't be adressable these days, since we cannot program voltage yet inside the bios.
Try lowering max boost clock, it is the main factor that make a card crash, and altogether increase your voltage a little bit, until the topmost card if stabl, then flash the bios every where and record the new voltage.
Some cards will run with higher voltages than necessary, but that is the cost of getting 3 cards stable all together.
PS . good explanation Solaufein for the actual state of the art in PSU design. All I know now is my 50A current limitation ...Edited by Goldust - 11/18/13 at 5:01am
