FSB downclock mod on the intel GL960 and GL40 --- useful info for PLL Modders

Is it possible to start P8800 on GL40 (Toshiba l305-s5919) with pinmode like on pictures above?

 

Hi
Check first page of this thread. In the examples it can be found toshiba l305 so BSEL mod is clearly possible. I'm not sure about bios support cos P8800 might need quite recent microcodes to work well 100%. Even without newest bios should boot and work cos it's Penryn core anyway.

 

For BSEL mod I need to make a jumper between A20 and B23? Have I left jumper with CPU or what is the procedure? As I understand
P8800 will work at 2000ghz at BSEL mod?

 

Yes, you need to make this jumper and it will force cpu to work with FSB 200MHz which translate to 2GHz speed.

 

In this way it is better to use cheap T8300 at 2,3GHz and thats all or try Q9100 at 1,7GHz? Have I upgrade cooler system in Toshiba l305-s5919 for 45w Q9100?

 

Yeah, it's better and easier to just use native 200MHz T8300 or T9500. If you want to play with this mod you can buy x9100 too, which isn't that expensive those days either and overclock it with multiplier using ThrlottleStop for example. I don't know really if quad clocked that low would be good idea. Someone would have to make some tests and comparisons.

 

And what about cooling system? Have I modify it in Toshiba l305-s5919 cause 45w it isnt 35w?

 

Has anyone tried pinmodding a D830/M4300 to use a X9100 or even a Core 2 Quad?

 

Hi
Guys, check firstly first page of this thread. It will give you some answers for your questions, like D830 mod. Quads most likely will not work cos they need additional circuitry which are rerly find on motherboards designed for dual CPU.

 

With the mod to place a 1066fsb processor in a santa rosa socket of 800fsb is it necessary to perform a physical modification of the 1066fsb processor? How is the cutting of some pines or just placing the cables in the socket?

I hope you help me I want to make this mod in an Emachine e528 computer with Intel Core Celeron 900 2.20GHZ 800fsb processor, and I would like this very informative before carrying out this test to avoid any kind of error in carrying out this procedure
