Hello, Everybody!smile.gif
I got problems in overclocking my notebook: Toshiba Satellite M100, T2350, from 133MHz to 166MHz.
After pinmoded the FLSB, It can't start.frown.gif
Could someone please tell me Why?

The frequency table:

The FSLB pin:

The circuit diagram about FSLB:

So I cut off pin 45(FSLB) from the pad, then connect it to a reliable high potential pin(such as: pin 41 FSLA, pin 7 +3.3v VDDA, VCCP etc.), but it can not start, I still get a black screen. frown.gif

Did I miss something?

I've updated my RAM's SPD to a slower timing, 266MHz works with 5 6 6 18 24 now, which is 400MHz's original:

I also disabled a core:

For testing, I tried these:
1.)When I get rid of R593, and place the 0k resistor to R587, then FSLB and MCH get a 1, so It would be starting at 166 Bus Speed, with the multipler 6x lock of course.
Test result:The CPU could run at 166x6.

2.)When I get rid of R593, and place the 0k resistor to R586, then FSLB and MCH get a 0, so It would be starting at 133 Bus Speed, as it was before.
Test result:The CPU could run at 133x14.

3.)When I get rid of R593, and leave R586/R587 OPEN.
Test result:The CPU could run at 133x14.So my pin 45 has a internal pull-down resistor?

Why I disconnect FSLB from MCH, then give FSLB a 1, and give MCH a 0, it's not working?
Is it unacceptable that FSLB and MCH have different electric potential?
With this question, I tried this:
4.)When I get rid of R593, and place the 0k resistor to R587, then connect FSLB to GND, What would happen?
Test result:The CPU could run at 133x6, Yes, the multipler was locked!

So, I can not OC to 166x14, because of my CPU is too weak?confused.gif
I do not really want to believe it.

Someone told me, Maybe a TME pinmod is needed.
But I can't find anything about TME in 9LPRS325's datasheet.

Help me please!
Any advice is appreciative!
If any PIC or PDF are needed, I'll post it at once.
