Update: Issue fixed, overlooked the arrow, thanks again for this awesome app, now if only the GPU observer gadget showed all three temps it would had be awesome. Hi, I had just bought the 580 Lightning and the MSI Afterburner 2.2b4 does not allow me to set voltage for the memory or the pll, just the core like a normal card. Driver version is 275.33, fresh build, this is the first driver that I installed. I'm running Win7 64b sp1, the NVAPII2C reports value for one register only, as far I understand it should report three set of registers right? :nerd: I uninstalled the afterburner 2.1, did a complete uninstall and then installed this version, your help is much appreciated. PS: Love the triple temp sensors.
