    Ola,

    I have 4x1GB of DDR2-667 at the moment on Vista 32-bit and I was wondering if 2x2GB of DDR2-800 would make much of a difference, other than freeing up 2 slots?

    I might also be upgrading to vista 64-bit sometime soon as well, which would then allow me to go up to 8GB RAM-wise ... not at least until the next pay check anyway.

    Thanks

    Anything in terms of more RAM on a computer can only be a good thing, so yep! go for it as it certainly would help to further boost your computer system.

    well thats the thing, it is not necessarily 'more' ram, just a different configuration and slightly higher clock speed.

    is 2x2GB better than 4x1GB?
    and
    is 800 that much better than 667MHz?

    I am reading about overclocking the memory at the moment, so if I go too far too soon, I may need more memory quicker than I thought. ha ha :biggrin

    I would doubt that you would notice the difference *if* the system used the higher frequency. However - it may not do that - depending on the rest of the machine (CPU/Motherboard).

    A higher clock speed like 1066MHz may not have a better latency than 800MHz. There isn't much in it between 800MHz and 667Mhz.

    it can use 800, the system is Core 2 Quad E6600 @ 2637Mhz (I have just oc'd it by 10%) and motherboard is an Asus P5N-E SLI

    and thanks GBL; I didnt really think that there would be much of a difference.


    I am now going to oc it by another 10%, up to 20%, and see what it does...

    dont do it too much or you will knacker the ram.

    I don't think you'll really see the difference between 667mhz and 800mhz, and doesn't Vista only really use 3gb (I can't see anything other than a high end server really utilising 8mb). Personally I would spend your money on something else... (or give it to me!)

    BTW I have the same mobo, I have 800MHz also the only difference between the 667MHz & 800MHz is the 2T timing.

    32bit can only address about 3.25GB, 64bit can see up to 64GB but I would never get past 8GB , just costs too much at the mo and would be a bit daft in a home box :blink

    thats 20% on the CPU, but the RAM isn't oc'd .. the option in the BIOS seems to be greyed out

    If I remember rightly you need to go to the chipset optiob and change the memory to manual so you can do it.

    yeh thanks, just did that and it went into power cycle free fall :ohmy

    talk about heart attack ... I just reset all to default and it rebooted OK .. time for a coffee and chill out ... :oops:

    I have just flash up to the latest bios using the ASUS update utility as well, so I may do some slight increases later when my pulse rate has lowered a bit

    As you can probably tell I'm a bit of OC newbie .. :D

    800Mhz will allow you to overclock higher than 667mhz ram.

    I'd recommend that you don't overclock on the stock heatsink+fan, you ideally need to have a custom fan or water cooling.

    For overclocking you should check the extremesystems forum (I think) or the overclockers, these guys will give you the best help
