    Memory question

    Hi All

    I recently bought 2Gb of DDR2 ram to replace the 1Gb I currently have. Does anyone know if I'm better off running 2Gb dual channel or plug it all in and run 3Gb without dual channel?

    Just running XP pro and do a bit of video & image editing.

    Thanks

    Hmmmmmmmmm now there's an interesting question..................

    In general dual channel gives faster through put which is what you want for memory intensive tasks BUT...... capacity is also important especially if you are editing large files.
    Large as in say 1-2GB plus.

    I would suggest one of two options :

    1. put in the 2GB in dual mode and use a swap file, (virtual memory) of around the 1-2GB mark. Make sure that the minimum and maximum figures are the same. This will give you the through put you need and the extra memory if you use larger files.

    2. If you generally use smaller files <1GB go for the full 3GB and a small swap file say 200mb this way you can store the whole file in ram giving you faster access and less seek time on your drive which tends to slow things down.

    So maybe you are thinking why not put in the 3GB plus a 1-2GB swap file, best of both worlds, well not really. The larger swap file compensates for the smaller capacity of memory and the dual channel makes up in speed the slight drop you will get in extra disk access and visa-versa

    If you do more editing than encoding go for the 2gb the CPU is more the deciding factor in encoding than ram, in XP over 2GB won't make that much difference.

    It is quite late and I hope this semi-drunken babble makes sense, if so GREAT !
    If not ooops

    Thanks Hang Over. I'd forgotten about the effect memory has on the size of the swap file and had better clean some more crap off the partition that Windows is on. Think I might bung it all in, reduce the swap file right down and see what happens.

    Thanks again

    32 bit XP too quite stupid really as the drivers for 64bit are a bit thin that is why I run two machines. but to stick to the question at hand put the three sticks in and enjoy it

    maximum physical memory limits:

    XP 32bit 4GB
    XP 64bit 128GB

    Vista 32bit 4GB (except the budget "starter" edition)
    Vista 64bit 8-128GB depending on version



    You will be fine with the 3GB

    I wouldn't laugh, 376 will run windows 98/2000 quite OK
    Struggles a bit with XP but ok if you are just doing internet and email.

    If it works don't fix it !

    Just because you CAN get a vista pc with XXX ram and XXX CPU doesn't mean you need to if your current one does the job. Some people feel they have to upgrade just because it's available.

    Saying that I just upgraded my PC
