680i vdroop is finally fixed for good!

Everybody with a reference 680i motherboard should be doing this mod. You have no excuse, its the easiest mod ever and will improve your overclock by miles!!!

All credit goes to symphy.

I am a believer, but this REALLY begs the question...if fixing a long-standing and much often talked about issue that Vdroop is merely requires a pencil fix...then why the fvck did the mobo makers not figure this out when they made the boards and fix it themselves before shipping the boards?

I mean this is really pretty bad when someone on the web comes along after them and shows them how to do their job...with a pencil.

Errr...probably because there is no "issue" to fix? In the course of following all these long-standing numerous discussions, did you by chance happen to notice this dreaded 'vdroop issue' seems to suddenly have struck motherboards from multiple vendors like ASUS, ABIT, Gigabyte, and others?

This is an intended behavior of the motherboard that is consistent with Intel's VRM design guidance (and prevailing industry design standards). e.g.

Meeting the Challenges of Power-Supply Design for Modern High-Current CPUs

Understanding Droop

The Rules Of The Game For Powering Today's Processors

VRD11.0 Processor Power Delivery Design Guide


The only reason this came to be 'fixed' by end-users instead of the motherboard manufacturer is because a lot of people were too ignorant to know that this was not any 'problem' to be 'fixed' in the first place, which the mobo engineers already well understood (being engineers and all).

I'm not convinced of these pencil mods. I have a feeling they're just hiding the real vdroop. Unless someone pulls out a meter and physically checks it somehow.

its not hiding it. my overclock is now stable with 1.40v in bios, whereas before it needed 1.50v in bios. why? because with 1.50v it drooped to 1.45v in windows, and 1.40v under load. now it says at 1.40v under load and its stable. so no, its not hiding it, its real.

This also works on eVGA nForce 680i SLI (A2)/NF63-TR (im not exactly sure what one i have the sticker on the board says NF63-TR but CPU-Z says NF68 A2)

No vdroop what-so-ever even under full load
