    The processors in the CF-51s are definitely upgradeable. I recently upgraded one of my CF-51 MK3s to a T7500 processor. I will give more details later. I am in the process of going back home and moving from one state to another.

    Would your MK3 be a T2300 @1.66GHz ? Sounds like a good idea but you must get the 2.2 cpu at a good price. i know Buybest (12,13,14 or 15) on fleabay has them sometimes for under $100.00 for the 2.2 . I paid under $50.00 for my T2300 1.66 DUO :D .It runs W7 great and I have upped the memory to 4GB / 160GB HDD.....sweet

    UPDATE: PLEASE READ THIS FIRST

    THE T7500 WILL NOT WORK. NO 800MHz FSB WILL WORK IN THE CF-51MK3 OR MK3LL.
    The T7200 , T7400 and the T7600 will work, These all have 667MHz FSB which supports the 51 MK3 / MK3LL motherboard / chipset

    No, actually it started out as a T2500 2.0GHz one. I got the CPU at a super price (FREE). Where this CF-51 started out as a CoreDuo, it is now a Core2Duo. 64bit vs. 32bit.

    Well I guess I am going to have to look at mine and see what board I have and see if it can take the faster cpu.

    So what I have found out without looking at the mother board is if I am right it should work in mine to, at least the sockets are the same.
    This was from the Intel site
    Intel® Core™ Duo Processor T2300 @1.66
    Intel® Core? Duo Processor T2300 (2M Cache, 1.66 GHz, 667 MHz FSB) with SPEC Code(s) SL8VR, SL8VV, SL9JL, SL9JY

    Intel® Core™2 Duo Processor T7500 @2.2
    Intel® Core?2 Duo Processor T7500 (4M Cache, 2.20 GHz, 800 MHz FSB) with SPEC Code(s) SLA3N, SLA44, SLADM, SLAF8

    Sockets Supported PBGA479, PPGA478

    wait the 51 I got rid of(2.0 duo 2GB ram) can take 2 duo? Guess I just put this 72 on pause again. Back on search for another 51.

    First thing to do is grab a copy of CPU-Z and look at the motherboard chipset that you have. Next, research on the web to find what processors that chipset will support. I don't remember all the specifics that led me to determine my CF-51 would in fact support the T7500. After my research I tried the T7500 and let me tell you, mine SCREAMS now. Your research will turn up very little about upgrading the CPU on Panasonics but you will find much more on doing this on Dells and HPs.

    Once I get all my stuff from Iraq and finish my move, I can post more info on this.

    Back 2 months ago I was picking up these on flesbay for $40.00-$60.00 (Duo) but now I see they are in the $100.00-$125.00 range with no caddy.
