BSEL Mod on a socket P explained with photos

[naton]

Hi guys.

I succeded on upping the FSB on an Acer AS 4315 laptop from 133 to 166 and to 200MHz via pin mod . The mod is simple, and can be done in 3-5 minutes if you can access easily to the CPU in your laptop.

You can use electric wire to do the mod. I used a wire from an IDE cable.

Note:
BSEL / FSB mod doesn't with Intel Chipsets
Undervolting mod works with all chipsets.

UPDATE: 27/07/2009
I updated the photos below because:
1- The undervolting values of the T2060 were wrong. I was showing the T5300 values twice.
2- There was a mistake on the photos showing the pin connection for Socket P.
3- I added Photos to show FSB mod for both Socket P and M

The BSEL mod will only work if you have:
ATI GPU + SIS Chipset
SIS GPU + SIS Chipset
nVidia GPU + nVidia Chipset

If the Chipset is an Intel one the cpu will be locked after the BSEL mod on its lowest multiplier

Enjoy!

UPDATE 15/02/2011
I added a few diagram to show the following mods:
FSB 133 -> 266
FSB 166 -> 266
FSB 200 -> 266

Wow - you're the first person to actually pull this off, if I'm not mistaken.
+rep and kudos, you've got guts, kid (2.6 GHz Celeron!).

Nice!
Does the Celeron feel any better/more responsive at this speed?

Pin mod on PM965 will only via PLL possible. Intel MCH now has a intenal check of FSB. If the CPU FSB isn´t the same like stored in MCH then the Multi will locked to lowest. So if mod the PLL and cut the connection between PLL and MCH then the OC is sucessful.

I wanted to know how to volt mod a Q9000 via pin mod on the W90 using the PM45 chipset.

I played the same game with and without the pinmod and the laptop feel faster. I didn't run any benchmarks yet.

Thanks for the info

Guys

1- Does the i965 chipset suppot 266 FSB?

2- Can anyone donate a Celeron T1600 CPU?

3- Is the T2370 faster than the T2500?

I run some benchmarks and the Celeron M530 pin modded is as fast as a Core Duo T2300.

what laptop/chipset do you have?
