how to measure the vcore?
sorry for noob question
The red "-" is the feedback pin of the vcore controller. The red X is connected to that point by a trace on the mobo. It's just for extra information, you don't have to do anything with it.

I don't have any vdroop problem with this board. It even slightly overvolts under load even without the mod.

I measure vcore directly on one of the mosfets. It's not the most accurate way to measure, but atleast it gives me some information.
