    In my opinion an example of average usage would be two browsers with ten tabs each, Skype, MSN, playing music with WMP, occasional usage of Word and Excel, some light photo editing, some zipping, unzipping, downloading and virus scans Not all at together at the same time but some of those tasks as multi tasking.

    That is a lot of browers to have open.

    What I usually have going on that kills my computer and reason to upgrade soon.

    Four browsers open with one uploading finished pictures to Smugmug, Lightroom, CS5 with major photo editing going on, email, streaming of the NFL network or any American show to my 58" TV via the HDMI cable. I thnk that wraps it up.

    I felt a difference upgrading from 6GB to 8gb. Added couple fraps in games. Why? Because when you have only 4Gb of in dual mode may be not enough if you use 1gb for eBoostr or dataRAM or spoil it elsewhere. Nowadays 1333 8Gb is cheap. very

    OP go for 8 GB and never look back.. with RAM prices cheap as chips you've no excuse not to fill up those memory banks....

    Loving the 8 GBs i got on my SXPS 16 which is now running 2+ years old but still a decent low end machine...

    1 GB RAM is dedicated as a permanent RAMDisk (starts up with Windows) to turbocharge application loading even more.. All my temp folders go there, and so do apps that i use on a day to day basis.. It's like a having a freebie SSD for most commonly used apps lol...

    Sometimes just for the fun of it I make a 4 - 5 GB temp RAMDisk on top of the 1 GB one to put games in and watch em load in seconds lol....

    DataRam and Imdisk RAMdisks are perfect for fooling around with when you have all that spare RAM...

    Solarmystic has a point, its ideal to get RAMs when they're at their lowest price point and it seems now is the best time to get them. Usual pattern is at first they are quite expensive, becomes affordable when it's mainstream then becoming hideously expensive again when RAM manufacturers cut down production for the next best thing. You only need to compare prices of DDR2 vs. DDR3 to see this trend.

    get the additional ram.
    personally i have 12gb for video editing. but i do see some benefit when i have many programs open, and while multitab surfing. it also makes alt-tabbing and ctrl-escaping between programs and games a breeze.
    with the price and benefits there is no reason not to get it.
    and also, regarding this normal usage/user talk- i really doubt that anyone who frequents this forum would be considered as such :)

    I remember 1 german guy who I met in Ukraine once and he had MASSIVE ROBOCOP LAPTOP (that's how I called it) with desktop Pentium 4 CPU (I mean Celeron). He could upgrade it to the max or at least enough to use this laptop with calm. Instead of this he turned off all visual effects in Windows XP (remember blue color in name field of icons on desktop?), used couple of some tweaking programs which possibly used more resources than freed and waiting for ever till screen refreshes after closing notepad for example.
    He had 256MB of SO-DIMM DDR-333, integrated GPU with 32 MB of video memory max and Celeron with 256 KB cache.

    When he didn't see I added 512 MB stick of RAM which was just lying in my room and changed in BIOS shared video memory from 32 MB to 128 MB. I think he noticed performance in Germany:):):)

    What is the point? His laptop was UNUSABLE while I could make a power business machine (or at least 5-10 times faster than what he had) from it using better CPU and more RAM
    Upgrade till you can and till it is cheap. In 1.5-2 years we will have DDR4 standard.

    I bought 12 GB of RAM to add to my already exsisting 4GB for a total of 16GB (the memory was super cheap anyway :p ).
    I normally browse the internet, play games and sometimes video or audio editing, result:

    I NEVER use my full 16GB...lol...

    Do you know that your 3GB video memory is shared? It has 1GB onboard + up to 2 GB is taken from RAM.

    Yup I know that. Eventhus someone told me that shared memory its a kind of myth. It's not really 2GB afaik, they claim that as propaganda,lol...
    However, let's pretend my 445M will use 2GB fully, still have 14GB..I am still thinking I won't use it.. :p

    Lol...you are right, I noticed just now.. :p

    I noticed the jump from 4GB to 8GB but it's not earth shattering. You will notice a somewhat faster response, especially if you multi-task between apps. Most games still are fine with 4GB and are GPU limited more than by RAM.

    I have 8GB of RAM, upgraded from 4GB months ago and never looked back. Really, I was amazed as to how I could cope with 4GB of RAM after I added the second 4GB stick. My usage typically goes like this:

    Chrome (<10 tabs), Outlook, WLM, Zune, Folding@Home (join us :D) and that's that.

    With the usage scenario described above, my RAM usage is 3.6GB (103 processes), even when accounting for Folding@Home which only consumes 60MB of RAM. This is with the computer on for about 12 hours, folding all the way. I plough through msconfig and services and have about 15 startup items, mostly related to drivers or essential software like Wireless Console so it's actually a best case scenario since I have more than 50 disabled items (blame iTunes, Intel, Microsoft etc). While one might argue that 400MB is plenty of backup RAM to spare in a 4GB system, if I were to play games such as Crysis 2 or Battlefield 3, 400MB of RAM is definitely not enough at all. Which is where 8GB comes in. With 8GB, you can do anything without really bothering about closing apps that you don't need to free up some RAM. Now, the hard drive becomes the bottleneck rather than the RAM, especially during startup. This is what I observed from my computer anyway, ymmv :)

    Others reported that when they upgraded from 4 to 6GB, they noticed a snappier system, even boot-up.

    The x64 Os is 'comfy' with 6GB, while if you have 8GB, you have extra to tend to other needs.

    if you have 6 gb only 4 GB will be really fast while 2GB you added are twice slower. 8gb is not just 2gb more than 6 but increase in bandwidth

    I feel the need to always be organized, I do not really use my laptop for anything professional. If I'm not using a program I tend to just exit it out... I'd usually have one or two things opened at the same time (a game maybe, and possibly Steam or chrome or something like that). I have managed to complete everything I wanted to on a 3GB Ram machine, including editing and rendering videos with Sony Vegas... but i'm sure i could of bumped up my performance by upgrading RAM. You can't really expect ram to boost performance but its always nice to have.

    I don't understand this at all :confused: Are you talking about dual channel support? Dual channel does not give a linear twofold increase in performance, and it was more noticeable in the DDR2 days. Now, the performance boost with dual channel is not so noticeable in DDR3 since it's fast enough with or without dual channel for most prople.

    DDR2 and DDR3 is just a name. DDR3 has lesser voltage but Mhz is Mhz anywhere. DDR2 is usually 800Mhz but happens 1066 in desktops. DDR3 in laptops starts from 1066. 1066 (DDR3) over 800 (DDR2) is not more different than for example DDR2-800 against DDR2-400. In fact the boost in the last pair is even more noticeable. So there is no point to say that after DDR3 standard came double mode is no more needed. LOL/

    1333 in single mode is only 667 Mhz which is worse than DDR2-800 in double mode.

    When you have 6Gb in 2 slots it means that you have flex mode where 4GB works at full double mode (1333) while another 2GB is in single (667). 667 is not what you want to have in laptop. Considering nowadays even 1333 is not even an average DDR3 frequency (1600 and 1866). Sometimes speed is more important than size.

    That's wrong. DDR3 has twice the transfer rate of DDR2.

    From Wikipedia:
    See above. Because DDR3 is twice as fast (theoretically), dual channel in DDR3 will not give as large a speed boost as compared to dual channel in DDR2.

    That's comparing apples and oranges ;) In fact, I still don't get what single mode and double mode have anything to do with this. Even if DDR2 is in dual channel mode, it does not give a linear twofold increase in performance, so technically speaking since DDR3 has twice the data rate as DDR2, isn't DDR3 still faster?

    From how I see it, if you have a 4GB module and a 2GB module, both running at 1333MHz, I don't see how the motherboard will throttle the 2GB module since if anything that would only contribute to latency issues. Both will still run at 1333MHz, except that you don't get the small speed benefit of dual channel RAM.

    Flex mode
    This mode offers the most flexible performance characteristics. The lowest DRAM memory in the system memory map is mapped to dual channel operation; the DRAM memory nearest to the 8 GB address space limit, if any, is mapped to single channel operation. Flex mode results in multiple zones of dual and single channel operation across the whole of DRAM memory. To use flex mode, both channels must be populated.

    Memory configuration for flex mode
    For the use of flex mode, DIMMs must be installed in both channels.

    The figure below shows a flex mode configuration using two DIMMs. The operation is as follows:

    The 512 MB DIMM in the Channel A, DIMM 0 socket and the lower 512 MB of the DIMM in the Channel B, DIMM 0 socket operate together in dual channel mode.
    The remaining (upper) 512 MB of the DIMM in Channel B operates in single channel mode.[​IMG]


    More about RAM channel modes read here


    About what you said at the beginning. Imagine 2 birds. They have 1 nest. And then they found magic wand which can double every apartment. So they created 2 nests from 1. But now image 2 birds have 1 empire state building. they think that magic wand is what they don't need because the building they have is big enough so they don't need to double it. (the bird is you). But who knows, maybe these birds are as big as King Kong but they just didn't understand it before. In this case they really will suffer that they haven't doubled that building before. See a point?

    I forgot that difference you wrote between DDR3 and DDR2 but I know that 1333Mhz is 1333*8=10666 MB/sec. And if my memory doesn't play with me it means 21333MB/sec for double mode.
