Many of the Q6600's made 3.0 with stock voltage, but if needed adding some should help. It also increases the operating temperature(not an issue with good cooling). Just do not go overboard.

What is approximate correlation between Q6600 overclocking to certain FSB, meaning, I just found tape mod to jump to 400 MHz (OP Optiplex might not even support this), which would be overclock to 3.6 GHz. So to be more or less stable, how much juice Q6600 might need?
The question, which will remain unanswered would be how much abuse Dell motherboard can tolerate.....
Inspiron 570 tolerated increase to 1.5 v, stable, from around 1.32 v, I am running at 1.42 v now, for the past 3 years.
EDIT. This is different story, but I seen tape mods to increase voltage (Q6600) as well, so those can help, just in case....

Okay I am back thank you all for helping me find this thread. in reply to Kisianik, The phenom I speak of is in its own system and is my favorite chip ( I have it running at 5.0 GHz on air @1.7 volts, and it was free hence why I like it even more.), I would like to give it a fair match with the q6600. I noticed that some of you mentioned voltage boosts. I was looking around, and there are various BSEL mods, all of which seem different, how do I know which one to use? also, I read of VID mods which involved shorting some pins to get more power, how do I do those? A lot of the things I read were on other forums, and all the pictures were down. There seem to be many options, but I only have one Q6600, and I really cannot afford to ruin either my motherboard or CPU. any one have pictures of what pins to do what to?

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.
Update on 01/08/2008
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

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.

Coming back a few posts, I asked which GPU you are using, if AMD, you can try Catalyst to overclock as well.
Also, question to public remains.
Can some one provide approximate voltages (what is normal and what is too low or too high) for Q6600 overclocked to 3GHz, 3.2GHz and 3.6GHz (if FSB possible @ 1600). I know it most likely varies, but some consensus should exist about this.

That takes me back to the AthlonXP wiremods. Was a great time.
I even still have one of those defogger kits from a v-droop mod on my q6600 system. I had voltage control, but it would remove my power savings so the vdroop mod allowed just the hair of extra load voltage. I never needed the Bsel mod because my board had FSB options a plenty and memory multipliers to match.
Intels official range is 0.8500V-1.500V. I mean do not go pushing 1.8 volts into it or it will die.

I would try catalyst, but right now I am stuck on an unstable ubuntu OS, and downloading either fails, or is next to impossible often. I'll try to get to 3.0 GHz, and if that fails try going to 1.4 volts, but wasn't there a 1.35 volt mod somewhere?

Nukemaster, That is exactly what I was thinking of too. only that one unlocked the multiplier. it is a shame this is next to impossible/ pointless to do today.

Just found a way to archived VID modes
Pin Mod LGA CPUs for Voltage Boost
Looks like pages selection at the bottom of the post is working, so you can see different default voltages.

It says that those are for core two duos, I assume it works on a core two quad? if so then I would do the 1.3... to 1.4 boost.

I got some conductive ink (that stuff is not cheap... $15...) I rigged up on of my E6400 chips with the VID 1.4 volt and BSEL pin mods, and will test it tomorrow when the ink has cured. core two duos and core two quads behave the same right? it certainly seems so. I hope to have results soon, and I hope I do not run out of thermal paste.

They should be similar.
The early core2 quad cpus are actually 2 core2 duo's on one die. Most likely highly binned ones because they did not require 2x the power of an e6600.
Intel never even tried to hide this. Arctic Silver recommended the thermal paste line go in a different direction to get both cores.
I did not know they had 45nm Q6600's. The 8xxx ones should have been 45nm

well, no results today... the one core two duo that I was going to test, turned out to be the one I had set aside for being no good from the start, so I have two more test chips with their pinmods drying right now. if those work, I'll do it to my core two quad. Also do you think we should go make a Q6600 OC guide/tutorial? it seems all of you no quite a lot about this stuff, and I feel I have learned quite a lot too.
in response to nukemaster, I am unsure too, as I also though the 8xx ones were 45 nm, but CPUZ says 45nm, and so did MSI afterburner.

That was my idea at least and adding how you setup setFSB to the mix for maximum power.
This actually would be applicable to huge number of Dell models, which can work with Q6600. As this will prolong shell life of those Dells for another 1-2 years as light gaming machines.

well the set FSB technique I used is a bad one, I just read the number off the clock generating crystal and matched it up like some forums said to do, it seemed to work, but as I mentioned, the highest I could get was only another .1 Ghz, and that was un-stable as hell, so I think there is a different number I should have put in, but I do not know which one.

It may have pushed the memory too.
If the board thinks the cpu is a FSB 333 part it may(or should) auto adjust the memory to fsb ratio to keep the memory stable.
On that topic. I have a board that when I use faster memory instead of using a memory/clock multiplayer overclock the cpu. That was an interesting side effect I did NOT want in my SFF system.
Would you want to add heat to something this small

Hm, drill holes on the side panel and place 120 mm high speed fan as exhaust or intake - where is the heat issue? Would not see any.
