    Can work through the PLLs faster if you can load a minimal XP install by doing a microXP+setfsb install. Some PLLs freeze the system requiring load/cold-boot cycles through the PLLs.

    Nope still can't find it. Any other software to find PLL?

    Great news, I have found how to make spdtool and Thaiphoon Burner work for me.

    For some reason they work after I press "getfsb" in setfsb.
    I guess they find it hard to read my smbus, but after setfsb does it they are fine.

    I don't really understand what's happening but I'm happy that I can now flash my ram.

    @kaltmond, how do you "hot flash" the ram?
    will the system boot with 1 bad stick and 1 good stick?

    another question:
    If I wan't to increase the cas latency from 5 to 6, should I change "cas latencies supported" from "4,5,6" to "6"?

    anyone did 200 -> 266 hardware pinmod working ? = multiplier s not locking with 1066 fsb.
    i own toshiba x205 s9349
    didnt disassembled it yet but google says it has ics pll
    so i want to oc it a little
    post pls whis details if u had sucess in this

    Amazing guide. A good help for me to continue my research overclocking my X9100 to greater heights. Thanks!

    I did 133 -> 166, 166 -> 200 and 133 to 200 via pin mod (tested on both socket M and P).
    I tested the above with two laptops; one with an ATi Chipset (Socket M), and one with an Intel chipset (Socket P). I didn't had any problems with the ATI based laptop. With the intel one, the CPU was locked at it lowest multiplier.

    The 200 -> 266 consists on connecting the two holes A23 and B23 on the CPU socket with a copper wire, or B23 and B24 with a copper wire. I haven't tried this myself (I don't have the right laptop to test), but it is likely to work.

    since this is a 33% overclock, increasing the voltage might be necessary.

    The PM965 valid FSB shown on the first post, duplicated on the right, suggest that is an invalid BSEL.

    FSB Capability: These values are determined by the BSEL[2:0] frequency straps. Any unsupported straps will render the GMCH host interface inoperable.
    01: (G)MCH capable of up to FSB 800 Mhz
    10-11: (G)MCH capable of up to FSB 667 Mhz
    [​IMG]
    PM45 valid FSB
    [​IMG]
    PM965 valid FSB
    I think there would need to be a different set of BSEL signals being seen by the chipset/PLL and the CPU for the system to boot *and* potentially work at 1066Mhz FSB as method 3 describes.

    I know that the PM965 doesn't support 266FSB :). The mod will work only with an intel PM975 / x4500
