I have done some FSB work to boost the base clock, Rob, but I only got to 2.5 GHz, because that multipliers is set at a low level. as for math geek I will certainly look into this, I am expecting one more person to weigh in on this thread before I give out best answer.

The bsel mod takes it from FSB 1066(266) to 1333(333).

As long as the bios allows it, just do that(that what I did with my Q6600).

Core2 cpus do not actually have a Boost. That is simply an overclock.

With boards that had a locked bios, the bsel mod worked as long as the chipset supports the new bus speed.

guess i should note that i also have one of these that i did this to and it gave a nice little boost. nothing major but not bad for the few minutes of time it took. i also have a basic intel mobo. this is in an old xps 420 system i have. no issues with it running like this so far

very similar to that mod. It simply tells the board the cpu has a fsb of 333 instead of 266.

What board do you have, Many allowed fsb adjustments upto the required 333. Also some old Nforce boards did NOT like overclocking core 2 quads(hell my intel 975x did not even like it damn board[payed extra at the time with high hopes]) so keep an eye out for that.

EDIT

Almost free performance :)

You do bring up a good point. The memory speed is linked to the FSB. most boards have multipliers to allow the memory to run at its default setting at various FSB settings. (166/233/333/ect).

Because of this it would be a good idea to check the memory speed with something like cpu-z before and after performing this mod. Your board may not allow voltage to be changed, so fingers crossed it is enough.

Yeah heat will be no issue I have two delta fans forcing air through a custom shroud I made over the stock heat sink which is quite large, I hope my motherboard will be able to keep it stable at this speed, as I do not think it will give the chip any more power.

yes this is needed. I did the same thing. You have to know your memory timings, as well as your clock thingy, as well as your voltage. I used cpu-z or hardware monitor to find this out...

Do not be surprised when the memory shows 400 in cpuz, that is normal.

Make sure to check it after the mod. Since dell uses many cpus, but only a selection of boards, it should deal with it fairly well.

If it does change(anything over 400 in cpuz), you will have to see if the bios has any options for memory multiplier.

Was it Dell with locked BIOS?

I am the one.

Many of my old links are dead by now, but some are still alive.
I did not expect many good suggestions provided already here so quickly (and I, personally don't care who will get BEST ANSWER as I am interested to keep information alive).
So, I would have to sort through my links first and then will post, however it will happened in about 10 or so hours (this is not my full time job, LOL).
There are so many different pin mode approaches in increasing FSB to 1333 on Q6600, so take it slow.

See you tonight.

400 is 800. the memory transfers data on the "rising" and "falling" edge it the signal so is double data rate. 400 = 800. Some software will report 800. It is just that, a report it does not change anything.

See Double data rate @ Wikipedia for more information on that subject.

You want more confusion check out the GDDR5 used on video cards. You will have a card at 1753 MHz but the rate is 7ghz.

Check out GDDR5 @ Wikipedia

Now I will be around to post and post, including tomorrow all day. Do you have AMD phenom II X4 965 BE in Dell PC, or you built your own with it?
And second question, do you use NVIDIA GPU or AMD.
Last Question, for now, have you ever reinstall your OS (which one you have now), if yes, have you used Dell copy, if no, have you loaded Dell Utilities and/or diagnostics after reinstall.
Why am I asking those questions.
Well, I remember now (after stumbling upon one post from my archives) that one of my partners in crime (overclocking Dell Inspiron 570 job) used first ATI Catalyst to attempt to overclock his CPU and it worked, not as good as me using AMD Overdrive, but it worked. And I remember that earlier versions of nTune were allowed CPU overclock as well.
Now I stabled upon the post where user stated that he was able to oveclock his XPS 720 with nTune (there is a possibility that this XPS had some options in BIOS allowed to overclock, so this may not be applicable to you), I thought that it could be possible to try.
[strike]What nTune old version, (I think this feature was turned off in the newer versions) and AMD Catalyst are doing, is increasing CPU voltage.[/strike] EDIT. During overclock there is also increase in voltage, however it is not controlled well and Dell motherboards are not that strong.
You can not try this on the original Dell sourced OS or original installation or if you loaded/have any kinds of Dell utilities, as I found out that Dell is placing lock to overclcock even on software level.
So once me and my partner reinstalled OS using Microsoft copies and did not load Dell utilities, we where able to overclcock our Inspirons on software level.
It is worth to consider at least, especially if you are ATI guy (I am NVIDIA).

I am still sorting out my last links on tape mod using even Internet cache services, since many of old links are dead by now, that is why it takes time.

Higher voltage wont increase speed, but when you overclock a cpu it will usually need more voltage to be stable.
