Intel T9550 for Dell Inspiron 1420

Oh,did you mean I should put a wire in these two holes like what I circled in the attachment?

Yes, I mean that. And than you need to install your T9550.

Whew, I just tried to do that, from using paper clip, stapler's bullet and string without success. The pad is simply too small for even a string not covering other holes.I really marveled at the pictures you posted......
Is there any other solution?

No easier solution without soldering the motherboard.
But you can buy compatible CPU: T8100, T8300, T9300 or T9500

OIC,but the price of them is twice of T9550.Is it possible to mod the BIOS to downclock the FSB by itself?I suspect that the picky BIOS can't even detect the CPU even if I manage to find something super small to put it at the two holes.I have been thinking about using cello tape to cover those two holes on the CPU,so will it works in your opinion?

the price of them is twice of T9550.

Downclocked T9550@2,0 GHz is almost the same as cheap T8100@2,1 GHz.

Is it possible to mod the BIOS to downclock the FSB by itself?

No, a clock generator selects FSB before starting CPU. So BIOS modding is senseless in this case - BIOS doesn't start at all.

I have been thinking about using cello tape to cover those two holes on the CPU,so will it works in your opinion?

No, you need to connect two signals in the socket, not just isolate.

To be honest,I thought this laptop support T9550 as I read some comments of other people.I never know they modded it/or just type the wrong name.So,instead of buying a T8300(which is almost the same price of T9550) I bought T9550.

If I manage to do that,will the BIOS recognise it?

OIC.Now i understand why you said it is a difficult BSEL mod.The socket is so small and I can't find anything like that.By the way,seeing that the point is not isolating it but connecting them,does it mean I need to use some material that is electric conducting or plastic things is fine as well?

[DeathBringer]

If I manage to do that,will the BIOS recognise it?

Yes, BIOS already has support for it.

Electrically connect.

Hi,I manage to connect it forcefully and now the BIOS and windows recognize the CPU.Now I will be trying to make it run in it's own nature speed of 2.66GHZ rather than the 2GHZ with SetFSB or something.
I am very grateful for your help.Thank you very much for your time and patient!

Your laptop is based on GM965 chipset. It doesn't support FSB=1066 MHz.
T8100, T8300, T9300 and T9500 are recommended for upgrade this laptop.
To boot with T9550 you need to make difficult BSEL mod: 1066 -> 800

BTW: BSEL mod 1066 (266) -> 800 (200) is the same as 533 (133) -> 667 (166)
Look at this - http://dxpc.ru/images/stories/pc/socketmandpfsbmod.jpg

Hi,by the way will the 166 to 200mhz BSEL mod works to overclock the FSB from 800mhz to 1066mhz(200 to 266)?Will the computer boot up if so or the mod is simply the same as pulling out my bsel mod LOL?Thanks

No, BSEL mods 166->200 and 200->266 are different. And hardware support of FSB=1066MHz (by a chipset) is required for second mod. E.g. PM45

Oh,so there is no way to overclock it?
