I understand but from my experiences, with vdroop enabled the core voltage should sit around what I have it set at in the BIOS and then droop a little under load. This is how my Asus board works. My EVGA board reduces the idle core voltage quite a bit and then raises it to what I have in the BIOS. This seems backwards.
"why is my idle temp so low with vdroop on? Shouldn't it be higher and then drop under load? Is this a PSU problem?"
I meant "idle voltage", not "temp".
I fixed it in my original post.
