    Hi
    I've upgraded my GL40 Chipset Acer Extensa 5630Z from a T3400 (Merom/65 nm) to a T8300 (Penryn/45nm).


    Fan kicks in now 5°C earlier (according CPU-Temp). T3400 has Tjmax 100 while T8300 has 105. I wonder if that is the reason.

    Integrated graphics clock is now 475 MHz, with T3400 it was 640MHz (GPU-Z). Is that because the T8300 runs now with a 800 MHz FSB instead of 667 MHz (T3400)?

    On the T3400 Core Volting dropped under 1.0 (0.950?) Volt when idle. 1.0 Volt is lowest for the T8300.

    HWInfo32 says:
    -that my T8300 is able to go down to 0.950 Volts (SLFM/DynFSB).
    -that my T8300 supports IDA but is IDA is red (disabled).
    -"Intel Dynamic FSB Switching" is also supported but disabled.
    -Enhanced SpeedStep is enabled.

    I wonder if I could optimize the settings for the T8300 with an "unlocked" Bios where the Menus for Intel etc. are visible and adjustable.

    thanks for some infos.

    Thanks.
    Don't get me wrong, overall performance is better now and Benchmarks of my T8300 are above average.
    Would 800 MHz RAM have an impact except that itself would be a bit faster? FSB:RAM Ratio of 3/5 (=200/333MHz) is quite common for laptops of that time.
