performed this vdroop mod yesterday and all i got was a board that didn't post and had a loud squeal in the general area that i performed the mod. the initial resistance on that pin was 13.7k ohms. i fixed a 50k ohm VR dialed to 27k ohms to the mod point. the resistance after the mod on the vdroop pin was 9.1k ohms. which means that it dropped in resistance.
it's beyond me. the mod should have worked properly. i made sure twice that i hadn't shorted anything and that the VR was a complete circuit. still nothing.. good news is the board is still up and going after i removed the mod.
If stock resistance measured at 13.7k ... then you would need much closer to 100k ohm VR for mod. I think resistance is too low... though for vdroop you can usually take it down to like ~2k ..so im a bit confused as well.
**You look up the ADP datasheet to make sure vdroop is correct?
**You try vmod first.. ?
