    PC question about Ram ?

    I have 3x 4gb 2000MHz & I'm using Windows 7 x64.
    The question is do you think 12gb is overkill & would you just used 8gb as from what I'm reading the PC will never use the other Ram ?

    Surely it can't hurt, especially if you've already got the RAM.

    What is the point of having it if it just sits & does nothing & then of course I could sell 4gb on here & get some money back.
    If it does add performance to my computer then I would keep it,but it looks like from what I read it does nothing.

    That's what I would do, it would be waste. Does your mobo even support 12gb? 8GB is quite crazy too and all you would need I believe.

    64 bit bit allows you to utliise more ram than the 32 bit version...

    Here are the upper RAM limits for the different editions of Windows 7:

    Starter: 8GB
    Home Basic: 8GB
    Home Premium: 16GB
    Professional: 192GB
    Enterprise: 192GB
    Ultimate: 192GB

    Only you will know if you fully utilise the 12gb as it will be down to what you use the pc for e.g. photo editing, video creation etc.

    My choice would be made on my current and future needs of the pc, do you expect your uses to increase in the next 6 months?

    Depends on what your doing with the PC, I've got 8gb in my main PC running mainly Sabayon Linux (64bit) but sometimes I boot into Win 7(64 bit) & I'm more than happy with it. Also got 8 gb in my mbp.

    My Motherboard can take up to 24gb.
    I'm also using Windows 7 Ultimate & use it for only browsing & gaming.

    oh you'll need another 12 gig for that

    Is it a triple channel (i7-9xx) or dual channel motherboard? That is the primary factor - if its triple channel, use all three sticks, if its dual channel, just use two, the operating speed will make more of a difference than the quantity of RAM for most tasks.

    Yes it's Triple channel,so you would say I would be better using all 12gb for gaming & browsing the net etc ?

    The ram will theoretically operate faster, but in all honesty the improvement is probably incredibly marginal (I'd guess at most 1 or 2%, even in demanding tasks) and for most uses you are unlikely to need over 8GB.

    You could try benchmarking with 2- and 3- sticks to see the theoretical improvement, but it likely to be so small you wouldn't observe it in day-to-day use...

    You could always sell and put the money towards an SSD,,,

    Then you probably only need 4GB/6GB. Depending on what motherboard you are using.

    God knows why people buy like 16GB or whatever, never really understood it myself. I always overclock so try keep the machines I build to the least amount required so it doesn't interfere with the overclocking.

    You can always Google for comparisons between; say, 4GB and 8GB when gaming, see which performs best. The article I have linked to is a few years old, but bear in mind, hardware might change a lot in a few years, but games really don't change that much. Also, minimum frames when gaming is more important than maximum figures.

    I guess you would want to look at 6GB vs 12GB for gaming. Web browsing doesn't even need 2GB.

    Generally as a rule of thumb, for gaming, you buy just enough memory. This then leaves you the option to spend more on things that make more difference, like a better graphics card, or a higher clocked processor.

    Something else people tend to do, jumping to quad-core, jumping to 6-core or even 8-core. If games are not utilising all these cores, then you would be much better with say, a 4Ghz Dual Core processor than a Quad Core at 2.6GHz. A quick Google on which games are multi-threaded and which aren't, how many cores are required etc can possibly save you £100s. Spend that money on a better graphics card and chances are that will make a much bigger improvement than a eight core blah blah, etc.

    ------------------------edit

    Just noticed you said you have 3x 4gb. You want to keep using Triple Channel so the only way you can change from that would be buying another kit, say 3x 2GB. Do not just take out 1x 4GB as doing so will force the system into Single Channel mode. Although it is said the performance difference between the 2 is minimal, it is one of those features you are better to utilise than ignore, unless you have a really good reason to ignore it.

    I think it would still work in dual-channel mode with two sticks would it not?

    Ah that would be good. I guess his motherboard manual will explain which slots to use. I guess the performance difference between triple/dual will be slim, although still not something I would personally advise. If you have a board that can use triple, might as well make use of it.

    If you have 3 sticks and the mainboard supports tripple channel then install it. If it is only dual channel don't bother as that will force the RAM to single channel.

    8GB should be fine for most stuff especially if you aren't working on large files or playing massively demanding games.

    I have have 4GB in my main PC and work on large Photoshop images all the time without any problems. If the RAM is gonna sit there on the shelf otherwise and if your board has tripple channel then you might aswell use it.
