    It seems IGP/LCD problem..I doubt it's a driver.

    from the descriptions of the problems... it is hardware related... either the Connector is loose or there is an actual MotherBoard problem

    Yes, 3Gb of RAM does work, at least I can boot into Vista ok and there are no strange symptoms.

    CPUz is saying that the memory is running in dual channel mode, but the windows experience for the memory has dropped from 5.1 to 4.8, which were the numbers when running with 2x1Gb and 1x2Gb respectively (Kingston HyperX 4-4-4-12).

    On reflection, the BSODs I saw with 2x2Gb tended to report pci.sys as the offending driver. I'm guessing that the problem is probably caused by device address conflicts in the 3-4Gb memory space. (ie hardware devices need memory addresses so that they can be addressed by the software - that's why 32 bit Windows will tell you that you only have 3200Mb-ish of memory available if you have a 768Mb graphics card, the graphics card's memory is mapped into the top end of the available 4Gb of address space)

    Maybe the address allocation parts of the Acer BIOS need a tweak - my son's Dell Inspiron 6400 boots happily with 4Gb installed - it just blocks access to the top 1Gb! This is much better than BSODs though :) .

    A quick update, my previous post is only true if the 1Gb DIMM is in the lower slot and the 2Gb DIMM the upper slot! Otherwise BSODs as before.

    I'm off to try running some test software to exercise the memory, inside windows and directly......

    thanx for the update, even getting it to use 3gb's would seriously extend the use of this laptop for future generations of windows. please keep us informed of your progress. thanx

    see the CPU GUIDES in POST #1

    you can use ANY STANDARD VOLTAGE SOCKET P CPU

    i'd consider a T8100 or T9300
    depending on what you want to spend..

    or you can always do like i did and buy a USED cpu off ebay...
    but stay away from anything labled as an ENGINEERING SAMPLE or ES version

    socket color is not an issue.... that was an error i made when trying to install a SOCKET M cpu..

    look thru the CPU GUIDES at SOCKET P cpus...

    there are a bunch of them...
    T5500 is a socket M and will not work in a 5315....
    T5550 is SOCKET P and will work
