    Okay, this may sound weird but does anyone know if there is a way to only use the 128 MB onboard Discrete RAM instead of the 256 MB Hypermemory. Is this even possible?

    Not that I know of, without editing the BIOS probably. Why would you want to do that though?

    i know this isn't helpful, but i DO think it is possible, but i don't have the slightest clue how to do it... :(

    try left clicking on the desktop. go to properties. go to the far left tab and click advanced. look around in that window, it should be all about your graphics card and settings and stuff.

    Mainly, to test out performance differences.

    If there's any settings for HyperMemory, it will probably be in the BIOS. Press F2 on startup to get into it.

    We'll be interested to find out the performance differences if you find how to disable HM. I know that for the dedicated X200M, turning off the shared memory helps performance - more memory bandwidth for the system.

    I went in my BIOS and saw nothing about HM. I'll check again next time I restart.

    As for Hypermemory it would be automatic..You could use ATITool to detect how many MB of VRAM a graphics card uses. Your graphics card only borrows the extra 128MB whenever the bulit-in 128MB VRAM is full...As for 200M , its bulit in , so its possible to disable HyperMemory in the BIOS

    while browsing around various notebooks in stores, I have seen an ati tab in the display settings menu to adjust the the amount of shared memory, I've only seen it on a few models though
