    I recently wiped my mum's laptop because it had all sorts of problems. It was an XP system but we couldn't find the XP disk so I put on the W7 RC which I have normally found to be very snappy. But the laptop is now very slow to do anything - start up, load programs, browse the web and even navigate in Windows Explorer.

    Here's the spec:
    Windows 7 RC 32-bit
    Intel Core Duo T2300 1.66 GHz
    1GB DDR2-533 SDRAM
    GeForce Go 7400

    I'm reluctant to put it back to XP, so the only other upgrade I can think of is the RAM. Would it help to put it up to 4GB? I'm only dubious because memory scores highest in the Windows Experience Index which would suggest it's not the bottleneck.

    Also, would the system support replacing the one stick of 1GB DDR2-533 with two sticks of 2GB DDR2-800?

    You are using a 32bit OS. Therefore 4GB RAM is pointless.

    I'd stick another 1x 1GB stick in there. I think you can use DDR800 in a DDR533 slot, it should just under-clock.

    Good point. But it could address 3GB, the question is would that make a noticeable improvement on speed?

    So if I removed the DDR2-533 and put in a DDR2-800, it wouldn't run at the higher frequency?

    More like 3.5GB isn't it? Which means you might as well do it.

    I'd be surprised if it did. It would carry on running at 533mhz.

    Laptop make and model?

    I reckon your CPU will be be the bottleneck if you upgrade the RAM.
    At the moment, however it does look to be your RAM that's slowing everything down.
    How many empty slots do you have? i.e. do you have 2x512MB sticks or 1x1024MB stick?

    Sony Vaio. Not sure about the model number, but on the bottom of the laptop it says PCG-6L1M and SZ2HP/B, if that helps.

    At the moment it's 1x1024 but there's another slot free. I haven't bought anything yet.

    Without the model number I can't say for sure. I think SZ2HP/B is the model number. I think you're limited to 1GB per slot so your maximum memory is 2GB. You should see a noticable improvement in multitasking if upgrading from 1GB. You're also limited to 533Mhz so don't bother getting 800Mhz RAM. I'd recommend going over to Crucial, good cheap memory and they have specialist who can help you out if anything goes wrong.

    Thanks, you've been very helpful. I've just seen that Sony give the full specification and indeed only 2GB are supported.

    Crucial don't seem to offer any DDR2-533, but now at least I know what I'm looking for!

    Hope this answers your problem, win 7 on a slow laptop like this will struggle. another gig or 2 of ram will help but id just put xp back on personally as what performance it had will be taken running win 7.

    It shouldn't struggle too much. Even Vista was very usable on 2GB. I wouldn't go back to XP as it's likely to have less driver releases and such in the future. It has only survived Vista because Vista was appalling when released. Windows 7 looks to be better than Vista already and final tweaking is yet to be done.

    FYI; I run Win7 on a 1.6Ghz dual core with 1GB RAM and it runs beautifully.

    Then why is my mum's system so slow?

    I've ordered another 1GB for £10, btw.

    I'd hazard a guess that you don't have all the drivers set up properly.

    Hmm, why didn't I think of that?

    OP suggest you take a look at the drivers again.

    I'd guess because you don't have loads of experience running Windows 7 on a very similarly specced machine. Can't really blame yourself for that eh?

    I on the other hand, have been running Win 7 on my rubbish PC for around 7 months now!

    Which drivers would have a significant impact on overall speed? At the moment I'm mostly using the Windows default drivers - I tried to install the right graphics driver but the nVidia one doesn't support Vaio and the Vaio one doesn't support Win 7 (and no luck with compatibility mode etc).

    Go with the most up to date Vista drivers for your VAIO.

    Ah yes, My i7 975 Extreme edition (OC to 4.5Ghz), 24GB RAM, Quad GTX 295 on my 300W PSU, runs it flawlessly though.

    All that on a 300W PSU? You pulling my leg? :p:
