    Acer Aspire 5720 CPU upgrade problem

    Hello all

    I have an Acer Aspire 5720 (the version with Intel's integrated graphics) which originally came with a T7300 2.00 Ghz CPU and 1 GB DDR2 RAM. I flashed the BIOS ages ago to v1.45 (from Acer) and I've recently upgraded to 4 GB DDR2 (all working OK). A couple of days ago I upgraded to an Intel T9300 2.5 Ghz CPU.

    The problem is that although the CPU is recognised as being "Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50GHz" ...it only runs at 2.4Ghz.

    Vista is (still) installed but I use Ubuntu (14.04 LTS) 99.99% of the time. Running "cpupower frequency-info" in a terminal returns:

    So it also looks like there is no frequency stepping (scaling?) available and it's always running at 2.4 Ghz.

    Does anyone have any idea why this 2.5Ghz T9300 only runs at 2.4Ghz with no frequency steps available?
