    Its using an AMD cpu (Turion II ZM 82). So, it should be running hypertransport 3.0 at 1800MHz (3600 effective). As far as the memory is concerned it should be a max of DDR2 800.

    Why a max of 800? Cant it be 1066 or 1333?

    Anyone knows whats the mobo of this notebook? If anyone have this notebook, a complete info(like gathered from the Everest software) would be awsome...

    Its weird..I dont find any info about this note, no one comments about it..


    --edit--
    If the mobo doesnt support 1800MHz its a waste of processor bus, this is possible doesnt it? Its more one concern about it.

    Me again, Im just started considering another thing..Isnt the resolution 1440X900 too high for this ati HD 3200? Since it is not a strong card, maybe this is a big issue of this note?...

    Sorry for the multiple posts, but Im almost buying it, need those info..

    HD3200 is an integrated card, in another words it is just one of worse, just beaten by Intels in crap department. But it is okay if you only do text processing and i am sure you can put it at 1600.

    Not really, not much improvement can be gained by going to the faster RAM unless if you are looking to squeeze every bit of performance from the system. DDR2 800 is quite sufficient for most people. This generation supports only DDR2 memory and so the highest supported is DDR2 800. The most current ones support DDR3 memory at faster speeds. The cpu bus is used for other stuff as well, so its still useful.

    BTW, notebook motherboards are proprietary and so you wont find info on these things.

    Should do just fine. The HD3200 is quite capable for those tasks.

    Good enough for current technology in that. If your thinking to have the laptop for more than 3 years i would say might be not enough. Caveat: i don't know what is going on in flash/java webgaming, if they have or go in short future for same resources needs than traditional PC games you might be in trouble.

    Thanks for helping me.

    Well, just to clarify AMD cpu's have the memory controller integrated into the cpu itself there is no need to talk to the chipset for the memory. Its direct memory access. The rest of the stuff is handled by the HT bus including talking to the chipset, PCIe devices, IGP etc.. there are several articles on the web with more info on the HT bus, you should check those out if you want more detailed info.

    Memory speeds are driven by the max capabilities of the chipset as managed by the BIOS.

    Deliberately buying 'fast' memory above and beyond what your machine can take is a serious waste of money.
