    Default Should i buy 2x2GB PC6400 or 4x1GB PC8500

    Hi have been an AMD user and currently i just bought a new Q6600 CPU and awaiting the release of 780i mobo...however i'm still in a dilemma when i comes to memory selection for intel CPUs.

    My Current system already runs 2x1GB of DDR500 on an AMD system and whilst Playing Crysis i see my Rams Maxing out at 100% and in terms of future proofing my next PC, do you think its not a good idea to get another system with 2Gb of Rams?

    Question is does it defer whether i buy 2x2GB of PC6400 rams or 4x1GB of PC8500 rams obviously PC8500 clocks better...what gives?

    Appreciate yr inputs and opinions

    i would recomend you get 2x2 gb of 8000 or whatever it comes in. you will get better oc's and you will be able to eventualy get 8 gigs. its gona cost more but i think its worth it, for future proofing.

    its hard to get 2x2gbs of PC8000 these days with good chips in them...i'm leaning towards getting 4x1gb of Crucial Ballstix PC8500 as they use Micron D9 chips and are good for DDR600 overclocked...any performance lost using 4x1GB vs 2x2GB ?

    Thanks again for yr inputs

    DDR2-PC6400 is very cheap now and same as PC8500.
    If you want a future proof then you should go with DDR3 ram (still very expensive) and its also depend on the MOBO. What type of memory it is going to supports, DDR2 only or DDR3. At the moment there are not many board that support both, just one or the other.

    If you're planning using Vista 64bit then get 2x2Gb sticks for future expansion. Again, a kit of 2x2gb is still a lot of money than a kit of 4x1gb.

    PC8500 has more room for OC than PC6400. If you filled up 4 slots of Ram then it doesn't OC as well as 2 slots.

    32bit OS only recognize up to 3Gb max but 64bit can recognize all the total ram you installed.

    I heard some reports ppl do have some issue with 8Gb ram with Vista 64 when you overclock it. Maybe Gareth Hale can clarify this. He has 8Gb of ram on Vista64.

    Normally, when you used up 4 slots of ram and overclock, it will put a loss of stress on MOBO. So it's cause the unstability.

    I have 4Gb of 1mb stick and run it at 800Mhz 4-4-4-12. I probally can push it to 900Mhz but I have to tweaking the timming which I don't have time to try it yet. If you want a stable overclocked system, you should keep the ram at it's speed. I don't have any issue with my mem at all, only I can't overclock any higher than 410FSB due to the mem hitting the brick wall.

    i wouldnt bother with ddr3 at the moment, its seriously over priced and generally has very high latencies.

    Indeed, when DDR3 prices drop later in the future, then DDR3 would be recommended, but the price its at now, its certainly not worth it.

    I'm on a 680i with 4x1gb 8500cd... its not been fun at all
    to be stable(ish) ive got to run at 4-4-4-12 and around 667-800mhz (900 max)
    It is possible to run 4gb at 1066 on these boards.. but youve got to have a 'good' mobo with good cooling around the mosfets (these areas and the northbridge get hot and stressed with 4 dimms). Im due a 780i (step-up) soon, so hopefully they've improved it.
    I bought 8500 as I was looking forward to o/c'ing but its been dismal so far.
    I mainly use my rig for work, ideally it needs to be stable, so for my next mobo, i'll be going with 4x2gb 6400.. and maybe not an nvidia board

    Correct!...it's all depends on how good your board are. I'm running 8gig @ 400fsb:533Mhz setting at the moment and no problem at all.
    In my case, 2gig stick x 4 is a tall order to push my ram like that and she's putting up with it
