[Request] Dell D630 Intel T9800 Support
#1
Hi everyone , thanks for any help

I'm upgrading my old laptop Dell D630 from the CPU T7250 to T9800.

After changed the CPU, it's not working at all. The power light turn on for a second and off itself without showing anything on the screen . 

Do anyone can help me to add the micro code of T9800 into the bios of D630?

The BIOS file of D630

The info. of T9800

Post screenshots of first (CPU) & third (Mainboard) tabs of CPU-Z with native CPU.

Yes,

   

   

It may confuse you cause the GM/PM965 support FSB 800MHZ only and T7250 also. 

Yes, I over clock the FSB from 800 to 1066MHZ and it works well , that why I'm looking at T9800 with native FSB 1066MHZ.

GM965 doesn't support FSB=1066MHz. So you can T9800 start with FSB=800MHz by BSEL mod and overclock to 1066MHz.

I already over clock the fsb to 1066MHZ , but it does not work at all with T9800 . What I thought is the bios does not include the microcode of T9800. 

What is BSEL MOD ?

Overclocking works after the motherboard recognise native FSB by CPU's BSEL pins. If a combination CPU's BSEL pins of isn't supported then the motherboard don't supplies a power to CPU.

To start T9800 you need to isolate BSEL1 pin! I've marked it by red color.

I'll add microcode to your BIOS if you successfully make this pin mod.

Ok , Let's me try to figure out , It's means for the PM965 chipset , It won't supply power to the CPU because the BSEL setting is 1066 on the CPU(T9800) , I need to config the pin of CPU to cheat the MB that it is a CPU with FSB 800 , Then I can boot it with FSB 800 with unknow CPU type (due to no microcode in the bios) 

Would you post the picture of how to pin the motherboard again? It's not showed .

Many thanks !

Look at the small red point, bottom right corner of the picture.
This pin(B23) must be isolated.

Hi

I cut off the pin B23(bsel[1]) of the CPU , But it still not work. Should I connect this pin to vcc on the M/B?

Why do not you just isolated this pin?!! Now you can't use this CPU in other laptop! Show a foto of your CPU without this pin.
But now you can try to connect in the socket(!) pin B23 to Vcc...
