    Hi there, I know that this question was asked long time ago in a previous thread.
    But I just need to upgrade the CPU of my old laptop.

    My laptop is set up this way:
    • CPU: Pentium Dual Core T4300 1M Cache 2.1 GHz 800MHz FSB; Socket P (478)
    • RAM: 4GB (2x2) DDR2 PC6400 800MHz
    • ATI Radeon HD 4570 with 512mb
    • Chipset: Intel GM45/GM47
    • Motherboard: Acer JV50_MV
    I want to upgrade the T4300 model with a compattible one with 1066 FSB.

    According to you, my current configuration will support this kind of switch (800 FSB -> 1066 FSB) ?

    Thank you.

    most of the 800 FSB laptop ive seen can't upgrade to 1066 FSB without some kind of hardware mod, so you might be stuck.

    Hi ole!!!, thanks for the reply. So when I was reading a similar (but old) thread, it seemed to me that some users have managed to change their old CPU with some more performing ones which have FSB at 1066 MHz.

    In your opinion is there a way to understand if the northbridge of this chipset supports FSB at that speed ?

    Or I just have to find out if there is a BIOS mod for this motherboard ?

    i have some of these old laptops myself to this day. 800fsb upgrade to better cpu thats also 800fsb. the same applies for 1066 to 1066. the hardware mod done by someone was from HDX dragon 9000 series that originally came with 800FSB which they did wiring mod and pin mod to take 1066FSB chips. more than a bios mod is likely needed.

    imo its just not worth the extra effort because they all end with dual cores.

    Upgrade the processor to the T9900 with a system bus frequency of 1066 FSB and BIOS modification from this: link
    PS> Recommended flash BIOS in DOS mode (boot with DOS bootable USB flash drive)
    "- run BIOS.bat"

    Bios also need to update what I given the link above.
    This modified BIOS reveals all the hidden features of this processor, and thus it is possible to further overclock up to 3.2 GHz

    Thank you @aidarin I will give it a try ;) . But how is possible to know if the northbridge of my laptop supports that frequency without reaching high temperatures of the CPU ? Is there a way or a manual that explains all this ?
