    Just curious, I have a T5450 CPU at 1.66GHz with a 667MHz FSB. Now, if I upgraded to a T7200 or something, would the FSB still be locked at 667 or would it now go up to 800? Remember, this thread is more of a curiosity than a definitive upgrade.

    The T7200, T7400 and T7600 which you could upgrade to have a 667mhz FSB, so your system will still run at a 667mhz fsb after the upgrade. The clock speed and cache levels are the only difference between the processors.

    OK, cause I was just wondering whether upgrading to a new Santa Rosa CPU would increase the FSB to 800 as they (I believe) are specified to run.

    I think your CPU is socket M not socket P so I think you are out of luck.

    Actually, I think The OP has a Socket P processor( See wiki)

    Also, If the OP has a Toshiba Satellite A200 TH7 w/ HD 2600 then he most likely has a "Santa Rosa" system since ATI HD 2XXX/NV 8 series were usually paired with Socket P processors/Intel Mobile 965 Express chipset(on the intel side).

    But check with CPU-z and see what it say by Chipset under motherboard/Mainboard tab.

    You got it exactly Kdawgca, it is Socket P on an Intel GM965 chipset. Just thinking back, I probably should have said whether if I was to upgrade the CPU would the FSB be downclocked, thus lowering the final clock speed, since I thought the higher clocked SR chips ran 800MHz FSB.
    For example:
    166MHz FSB * 10 multiplier = 1.66GHz final speed
    vs
    200MHz FSB * 10 multiplier = 2GHz final speed
    vs (what I'm curious about)
    (200->166 due to chipset (if that's the limitation)) * 10 multiplier = 1.66GHz FS even though it should run at 2GHz.

    kdawg I was on the run, never listen to k-tron :D but he sounded convincing. Now I wanna know, kan notyou do what he wants and will it go 800Mhz? Or is it locked some where? :eek:

    My HP dv2533 was a T5450 1.6Ghz @ 667FSB. Socket P yes.

    Santa Rosa supports 800fsb to the cpu, but NOT the RAM, only 667max.
    It's ok since the ram is DDR2.

    So, install a 800FSB spec cpu, like a T7500/T7800, or even a Penryn T9500- there is little reason outside bad bios support - to let your laptop fly.

    It will detect via cpu pins, and run 100% perfect.

    It is only for OEM to decide what cpu to fit.

    Ahh, ok, so it will change the CPU's FSB but still keep the RAM FSB that makes sense. Looks like I may have to upgrade to a penryn for 10% performance/battery life boost.
