Question Tweak For BIOS Help To Support CPU needed

[Userofinspiron1420]

Recently, I bought a T9550 CPU, thinking that it can be supported by my Dell Inspiron 1420.Turns out it isn't, eventhough almost all the spec is the same.
The differences is the BIOS and motherboard(but the socket support it) not supporting it.
Here is my computer spec currently:
OS: Windows 10 Professional
Motherboard: GM965
CPU: T5250
BIOS: Phoenix ROM BIOS Plus Version 1.10 A10 (the latest one for Dell Inspiron 1420)
RAM: 2GB DDR2 800FSB x2
I guess the solution is to tweak the BIOS into downclocking the T9550 to 800FSB as it is the only indifferences of it with the motherboard to make it support.Please help me if you know how.Thanks!

Welcome to the forums, newcomer!

I don't think it's going to be as simple as downclocking the board/BIOS settings to get your T9550 to work, it's more of the fact that the BIOS might have a white list of parts supported by said motherboard. Might want to read through this thread's post as well as this thread's post.

Yes,I read those posts before buying the T9550.I should have just buy a 800FSB CPU like those posts and do more investigation before buying it :/ Is there anyone here that knows how to tweak the BIOS like this following forum Install a 1066MHz FSB CPU on T61 (including Core 2 Quad) - Thinkpads Forum ?The spec is exactly the same(GM965 and T9550) except the model of the computer .

Solution here:Intel T9550 for Dell Inspiron 1420 (bios-mods.com)
anyone considering to do such a mod will need to cut off the cable of a plug(for my case a three pin plug)
,take out the three wires(picture),get three copper wire(or possibly more but I didn't try it,10 is too thick I tried before) out of them(the golden colour one like shown in the picture) .Now,twist and turn to make the three wires to become one wire.I tried using just one copper wire and it burnt after a few hours but luckily it didn't make the processor socket melt or something :/

The guide linked above seems to have pretty much all info necessary for said CPU mod, though the gauge of wire needs to be spot on or you can end up doing harm than good. Link to the image in said guide linked above;
