Hi! This is my first post here, so I'd like to thank you all for having me here as well 
.
I have an old Dell Inspiron 1520 laptop that came with a Core 2 Duo T7300, Merom, 65nm. Its FSB is at 800MHz so the best upgrade I could do to it would probably be a T9500, Penryn, 45nm.
I've seen online that the motherboard perfectly supports that processor so I'd already be happy with it. But I'm a tinker so I got me a cheap T9400 to do some tests, it's a Penryn era processor as well but it expects or is configured to use an FSB at 1066MHz. Searching around I found out that there's something called BSEL modding that's usually used to go to higher FSBs but there's the possibility of down as well.
In this case I think I have to isolate one of the CPU pins (as per the table in this post, and that ought to be enough. At least until I realize the microcode for the processor is not present in the BIOS and I would need to mod that too... Even thought I've been doing some reading all of this seems quite daunting to me because I don't understand some of the terms used in this kind of mods.
So for now this is what I've tried, I've put the chip in and tried to boot up just for the sake of it, which ended up with the laptop shutting down obviously. Then I tried to isolate (meaning... taping? disconnecting?) the BSEL1 pin with electrical tape to get it to use 200MHz increments. But these CPUs are still those that come with actual pins, i.e. with copper sticks coming out of it. So what happended was that upon putting the processor in its socket the pin actually punched through the tape, and I accomplished nothing. I thought of removing the pin altogether, but that sounds extreme... there ought to be a better way of doing it.
So my question is... could someone guide me through the process or point me in the right direction (maybe there's already a guide I couldn't find or some useful reads)? In any case this is just a test to see if 1066MHz FSB Penryns can work with the laptop, the idea is that I can mod this 5$ CPU and make it work I'd look into a more powerful one to repeat the process.
Thanks anyway for your time, and reading through all of this.
