Now back to much anticipated post. Here I will post everything I have.
This came from the source, which doesn't exist any more, I was able to resurrect it using Internet cache services.
That would be a
QUOTE, but I will leave as text for easy cut and paste for others, if needed, will state "
end of quote" at the end.
It is supposed to increase your FSB from 1,066MHz to 1,333MHz (Quad Data Rate). So your CPU should effectively boot up at 333MHz X 9 (stock multiplier of the Q6600), for a CPU frequency of 3.0GHz.
LGA 775 processors give possibility to raise the bus frequency to 1066 MHz and above by closing some contacts on the processor - the so called BSEL mod.

Modify your Core 2 Duo CPU
After my guide about overclocking a Dell Dimension (90% success stories, thousands of pageviews), it's time to write about how to modify a Core 2 Duo/Quad processor so it will pass 333 Mhz instead of 266 Mhz to the mobo (or 266 instead of 200, or 333 instead of 200).
All you need is a pen with conductive ink (to connect two or more 'pins' and some tape (to protect surrounding 'pins' or to disconnect them)
The pinmods below should work for every processor that fits in a LGA775 Socket.
fsb266-333
fsb200-266
fsb200-333
A green dot means: put a tiny piece of tape on the pin, the red lines mean those pins have to be connected with conductive ink.
Use the RightMark CPU Clock Utility (do not use cpu-z) to find out if your CPU is running stock at 1.325v. or 1.2875v. (When EIST/C1E enabled then read it when your CPU is under stress, because when the CPU is idle, it will show a lower voltage).
Q: How to undo?
A: Use nailpolish remover to remove the ink, and/or remove any tape that was put on a pin
Q: Will this harm my processor/system in any way?
A: No, it's perfectly safe (as long as you connect the correct pins)
Q: Will this violate my warranty?
A: Yes of course

Please read all comments, there are success and failure stories.
Now here is the link to another forum with 52 pages to read, if pictures are missing, look at the one I posted (this is the reason for posting)
http://www.overclock.net/t/341123/intel-bsel-vid-mod-guide
This post explains everything electrical in great detail and provides a way to increase FSB even to 400 (1600MHz), will your board allow this , this is the question, but it is a good post. http://www.overclockers.com/intel-lga775-pad-modding/
This is strange picture about increase from 1333 to 1600, it doesn't look like others and link is dead and not archived.
And finally VID pin mod - voltage increase
intel conroe voltage pin mod
Remember those are all LGA775, so it might work since socket and pins are the same.
Conductive ink. I found ones that had been referenced in those posts
Permatex 09117 Complete Rear Window Defogger Repair Kit
CircuitWriter Precision Pen silver-based
I think this is all.
When you will be ready to start, if ever, return your FSB back by set FSB, apply pin mod and use set FSB again, I seen multiple statements about such approach leading to overclock to 3.2GHz. And I provided the way to try increasing FSB even higher, if it is ever possible, you can find out.
THE END.
EDIT is done, all complete, pictures working.
