The P30 bios has been really good to me. It enabled me to boot up at 3.6 (400 FSB). I also just did the vdrop mod to my board today as well, while dusting out the radiator. So far it's all good! I can use a much lower vcore now! I ended up using a circuit writer pen that I got from Radioshack a couple of years ago when the nForce 4 from DFI was the rage (used it for the SLI mod on Ultra-D).

Thanks for the pictures! It really helped!
