    Since im pretty new to this forum, i would like to ask how i can find out how fast ram my notebook supports, currently it has two 333mhz in it which is pretty slow, but is that as fast as it supports? Also, i would like to know how fast my HDD spins, vista experience index gives it 5.3 rating but that sounds like bs to me since (i think) that it is only a 4.200rpm

    The i965 chipset, in your notebook supports memory frequencies only upto 333MHz....Thats the limit..!!
    A 4200RPM HDD is pretty slow. You should consider upgrading to a 320GB 5400RPM/7200RPM HDD....!! You will get a real boost in boot times and application startups....
    Vista's WEI is crap.. :D

    To do a proper synthetic benchmark, download HD Tune and do a Read Benchmark in it....It will give you an idea about how fast your HDD is, as compared to the newer, better HDDs.

    No way.. :D
    Can you upload a screenshot of that first page of HD Tune with the benchmark result....!!
    There will be a 'save screenshot' button at the top..!!

    DUDE no way that is a 4200RPM HDD..!! :eek:
    It is the Western Digital 320GB 5400RPM HDD, same as mine.. :D (check my sig, WD3200BEVT ;))
    I actually get 54MB/s as average..!! I hope it is in AHCI mode....
    Anyway, that benchy is fine, since some background service is pinging it at the end, hence the fall..!!

    Yeah, you will get a little boost..!! (BigO says it increases chances of data corruption :eek:)
    I know of a way by which you can enable AHCI, after installing XP, but it is a little bit risky.. ;)

    You can check this out, if you would ever want to re-enable AHCI.... :D

    But after doing some research myself i found out that i dont have a i965 but a PM965 and that should indeed support up to 667mhz.

    this is from intels website :D
    So i guess i should upgrade my sloppy 333mhz as fast as possible.. :p

    No, I meant by i965 - GL960/965GM/965PM (was referring to the chipset family)

    The Ram installed is DDR2, so the frequency is 333.xMHz * 2 = 667MHz....
    So, you already have the ram with the max frequency..!!

    Frequency of the ram really doesn't matter in your case, because if you have two DDR2-667 modules installed, the max bandwidth of the ram is 5.3GB/s * 2 = 10.6GB/s, which is bottlenecked to 5.3GB/s (166MHz * 2 * 4) if you have a CPU with 667MHz FSB installed.....
    [Hence memory divider 0.50 (1/2)]
    So the frequency of the ram won't really improve performance at this point..!!

    You can confirm this through CPUz....
