for vdd if you think that is the problem, and you are getting TEMPFILE errors during prime, select 1.4volts in bios. this is a bug which allows 1.8 volts 
i did it. got me 2 more fsb.

Pics of Boards
Modded/cut trace.....
be carefull. you must gentally cut the trace w/ a rasor(or similar) and gentaly scrape the coating off the traces so you can soder to them....
all done..... i would suggest running the wires and VR to the other side of the board, this was done only for testing befor the mod was acually figured out
and a close up......
and another
heres the Vtt mosfet......

You can also read the vtt voltage off that mosfet. The pins that read 1.54 and are circled in blue in the pic are vtt checkpoints.
I recommend, with any of these checkpoints, to solder a wire to it. Run that wire to a molex connector dedicated to voltage readings. That way you won't accidentally slip with the multimeter and short something out on the mobo.
*Edit*
I just noticed the last pic in Jess's post there are white lines pointing to the vtt measuring points on the vtt mosfet. So my pic is redundant.

Yeah, you need to scrape it down to the metal. Otherwise your wires won't make electrical contact.
For cooling, refer to the link I posted in post #5. Sink that vdimm mosfet. You'll want to sink your southbridge too. Use one of the small heatsinks that comes with the Vantec fan. Also, use Arctic Silver on the northbridge HSF.

, i got no as5 yet, but the vantec kit is the one thats copper and comes iwht a sb,nb, and vga hsf, gonna use the vga one on nb, guess i need to order some as5 and some sinks, b4 i get started, got lots of wire from old psus guess i need several 1k resistors too?

yes you need 2 1k VR's. one for the Vdimm, and one for the Vtt. also it doesnt hurt to sink the Vdimm mosfet. the reason that i suggested the Vtt read point on the back of the mobo, is because the mosfet needs to be sinked, so the w/ the sink on top on it, it is rather inpossible to get a multimeter to. also it is hard to soder a wire to it, and still put a heat sink on it. so i would sugest runing a wire from the Vtt read point on the back to a dedicated molex conecter to measure voltage, as zachm said.
i really wouldnt do the VDD booster....

so 2 of these: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4664&item=3822458032&rd=1&ssPageName=WD1V
and 1 5k or 10k trimmer?

sorry bro....
thoughs are single turn, for Vmods, you need atleast a 10 turn, that would be way to sencative
i would guess that 2-5 degrees or less of rotation would be the diff between 1.7-1.9v. )i think its touchy enought w/ my 20turn 5k VR........

I've got a question about measuring vdimm. I know you can measure vdimm from the mosfet on the front of the board. I want to put a heatsink on that mosfet though. So soldering a wire to the mosfet leg to measure vdimm would interfere with the heatsink. I know you can measure vdimm from pin 7 on the dimm socket. Does anyone know where I could solder a wire to the back side of the board to measure vdimm? Here is an example of where I think might be the vdimm measure points (edit: pic is no more). I'm confused on which #7 I should solder to because there are 4 rows of pins.
