    marooned in a memory muddle.


    hi,
    i have been thinking about getting some more ram for the 2 slots i still have open in my pc but it seems the ram i purchased for it back in '04 is no longer made! now im a bit confused as to what i should go for. i dont want to spend the money only to find out its not compatible..

    currently installed i have,

    slot one:

    Type DDR
    Size 1024 MBytes
    Manufacturer Hyundai Electronics
    Max Bandwidth PC3200 (200 MHz)
    and the same in slot 2.

    i can find ones that match the type and size but not the 200mhz...would installing some with a higher bandwidth cause problems? im a bit lost. help!

    if anyone could provide a link or 2 to uk sites i would find that most helpfull! the cheaper the better! thanks:)(i would also like to increase ram by the gig and not mbytes if poss)

    Most, if not all, will agree
    Dont mix and match ram, even if you can find compatible
    If you want to do it right, buy all you need and remove ram that is currently installed.

    ouch. that sounds expensive! thanks for the advice

    edit:

    would removing both slots of the ram i have installed now and replacing with this:

    Corsair 1GB DDR 400MHz/PC3200 Memory Non-ECC Unbuffered CL3


    be a good move? (sorry about the bold!)

    another edit. having thought about that,if i remember correctly there are 1000 mbytes to a gig,so i would have less ram than i do now. my bad.

    Yes, it is expensive, but its more expensive to buy ram that is not compatible.
    Ram has frequency and frequency (most important) and other factors have to match perfectly or there are problems.

    VS2GBKIT400C3 Corsair Value Select 2048Mb (2x1GB) Kit 400MHz 184Pin PC3200 CL3 : novatech.co.uk

    Which is as much as it may hurt to hear, is pretty much more than your whole computer is worth. Also another thing to consider is if you have any plans for a new computer in the near future, then any money spent on upgrades for your current computer will be wasted as you will not be able to move any new parts (short of a hard drive) to a new computer.

    i can find ones that match the type and size but not the 200mhz
    That 200 MHz is the FSB the ram is rated to run at, which with being DDR means the effective speed is 400 MHz (don't forget DDR stands for double data rate). If you do still want to increase the ram in it I wouldn't go any further than up to 2 GB, which with that old SiS chipset (would help if you listed the actual motherboard and not just the chipset) you would probably be able to get away with the cheapest 512 MB stick you can find as dual channel isn't a factor as it isn't supported by the chipset (that was only supported on the old Nforce 2 chipset, and even then only provided about 5% extra performance if you were lucky). Also grab this,

    CPUID - System & hardware benchmark, monitoring, reporting

    and on the SPD tab it should show what timings your current ram is rated for. Then just look for something with the same speed and timings (a little lower if you find it should be OK as it should downclock to the speed/timings of the slowest stick).

    ok,thanks stormy..im trying not to cry after what you said about my old beast lol,i know its old and underpowered but its lasted me a while now! as long as i dont want to do anything too intensive on it,it does run pretty good.i dont use it for gaming or anything like that really,i prefere consoles,but it is high time i got a higher spec system and finally put this one to bed lol

    i am planning on getting a better system in the new year so like you say,maybe its really not worth doing any upgrades on this one. and on the new system im going to make sure i have at least 2gig of ram,as i will be wanting to use it for more performance intensive stuff. as for the info on my motherboard,all the info i have on it is what speccy brings up for me which is

    Model SiS-748
    Chipset Vendor SiS
    Chipset Model 746FX
    Chipset Revision 10
    Southbridge Vendor SiS
    Southbridge Model 964
    southbridge revision 36

    i had and have no idea what any of that means so didnt know if it was relevent or not!

    I think that the advice that you were given is right on spot.
    Money is tight everywhere. Try to make do with what you have and save the money. When you are ready to buy, you will have that much more to spend on a puter that will make you very happy.

    You'd get better compatibility information if you could identify the specific mainboard. SiS 748 is its chipset type. The free version of SANDRA from:

    SiSoftware Zone

    may give you more specific information.

    I don't buy from the UK, but you might take a look at:

    DDR upgrades from Crucial.com

    Choose DDR PC3200/DDR-400, 184-pin DIMM, Unbuffered, non-ECC. The largest DIMMs that they offer are 1GB each, 2GB for a matched pair. The price is £74.01 inc. VAT.

    You may be able to get them to play with your existing RAM, but it might require manually setting the memory voltages and timings in the BIOS setup. Buying two pair may give less frustration, though.

    I don't know whether to recommend such an upgrade. If you already have 2GB, that's not bad. As your PC probably dates from 2003, saving your money for a total system replacement may be wiser. You'll be pleasantly surprised with the performance of even a low-end desktop PC compared with a system that old.

    The old DDR was a lot more forgiving when running different sticks than the DDR2 and DDR3 of today. For what it's worth (kids computer),

    marooned in a memory muddle.-oldcomp.png

    Old ECS board with the same chipset on it with a pair of mis-matched sticks in it, and been running that way for the pasty year or so (and had 3 different sticks of 512 MB for a few years before that) and is as stable as an old comp can be. Only reason it has the two 1 GB sticks in it is an old socket 939 board I had died, so I recycled the ram from it into this one.
