After: 1.3v BIOS Idle 1.248v Load 1.248v

However, I couldn't figure out a way to protect the pencil graphite from dust/airflow. The mod failed to hold after trying scotch tape and silicone grease over the resistor. I went to Fry's and bought silver micro conductive pen and here is the result:

1.3v BIOS Idle 1.280v Load 1.280v

With vdroop mod, I'm now able to get 3.2Ghz (400x8) using default 1.3v and best of all - able to enable C1E & EIST.

Idle: 2.4Ghz (400x6) Vcore 1.152v Core0 27C
Load : 3.2Ghz (400x8) Vcore 1.280v Core0 51C
needs some conductive ink
