Hmm I'm still tweaking my GTL1 and GTL3 refs but it seems core4 is my slouch and is always dying in prime.
Anyone know some good VTT settings for the qx9650? Right now I'm running 1.36 VTT and 1.3625 Vcore.. I'm just trying to tune the GTLs so that I get a solid prime and then I'll bring down the volts.

So far I've tried +3 percent (so 70 percent, but 70-67 percent requires a +3percent*vtt*1000 = x mV increase) and I've tried negative values too.
Anyone else have any experience with the GTLs, have negatives worked well for anyone on quads? Not duals? Does more GTLn ref ruin stability or just feed excess volts and not affect stability? Really trying to fine tune here and seeing how far off I am to get the right values.
