Just wanted to report back with my results. I ran out of conductive ink so I settled for the #2 pencil approach. I did a measurement initially and!! 130k ohm?!?!?! my dmm is still low on battery, and was giving inaccurate results when I used it a week ago, but in some preliminary testing, it's seeming to be ok. also, I warmed the battery in my hand for a few minutes if that helped.
But anyway. Initial was 130k instead of 80k?? Ok. I started shading up a storm. I remember doing the pencil mod on my 7900gs and I was there for minutes shading. So I shaded for a full minute or so. Checked it again. 5k ohm. Hmm.... way lower than the 14 or so you tested. Alright! Boot it up.
The p5b vanilla is starting to show some ugly cold boot issues I thought I was escaping when I left the ds3 but oh well. It died the first time so I pulled the plug and tried again. I went in bios, and it was at failsafe 266fsb again with 1.325v vid. I check vcore in bios and am seeing 1.320v. Cool. Right around what vid of 1.325 is. Put back the 1.425v I needed before vdroop mod just so I could establish a baseline.
Boot into windows at 8x400=3200, 1.425v set vcore.
Fire up cpuz and speedfan. Speedfan reports 1.42v. Ooooh.
Cpuz reports 1.424v. Holy smokes.
Fire up orthos to load it. It goes up to 1.432v and hasn't budged. Sexy sexy.
edit: I'm down at 5k ohm now and am liking it a lot, but I'm still curious what 0 ohm would do. better not push luck right at this moment though since I'm so satisfied with the one minute of my time. Now time to explore any possible p5b vanilla vdimm mods.
update: 1.35v set vcore. 1.344 idle. 1.352 load. gorgeous figures. looks like it pretty much countered vdrop as well.
