    Question Difference of RAM

    I was wondering what exactly is different about RDRAM, DDR, SDRAM, etc. For example, what type would be good for a barebones AMD computer that would run mandrake/slackware, have dsl, and just be a computer to surf. I would use it to program on, but would perform anything extensive on my high-end computer.
    The only good thing about freezing beyond feeling in the final Nordic ski race was that I couldn't feel that tumble I did going about 30 mph, maybe more.
    On the other hand, not feeling any part of my body for 30 minutes was scary, especialy for my manhood.

    Windoze: XP, hate it, though its more stable than my old 98SE
    Dream: linux, mandrake, then slackware.

    DDR ram is (theoraticly) twice as fast as SDR ram.
    I'm not sure RD ram (another INTEL invention *sich*)

    So, you would need less ram if you got DDR than SDRAM?
    But can you put both on the same mobo?

    If you are using AMD, go to DDR, it's faster than SDR.
    But RDRAM is faster than DDR (Just for intel) and you can see this here, http://www.pcstats.com/articleview.c...d=1096&page=5.

    Check out that thread to see if it answers your questions... and if not, back up to the hardware forum on that site... there are several good RAM threads that cover most anything you're asking.

    Can you put a v6 and a v8 in the same car?

    Maybe if TravisDane did his research...

    YES. There are lots of mobos that have slots for both types of RAM, SDRAM and DDR. Several even have slots for both SDRAM and RDRAM.

    Incorrect, my mother-board support RDRAM and DDRAM.
    I don't need to change my mother-board if I want to put ddram (I'am with rdram)

    Yes there are, mine included, (ECS P4S5A), however, I cannot use both types at the same time, one or the other.

    I have 333MHz PC2700 DDR.

    It is HIGHLY UNRECCOMENDED to mix RAM types, even if the Motherboard will let you.

    Windows and Linux and any other OS will have majpr problems.

    Imagine this, trying to use two roller skates, one without a motor and the other which can only go at 40mph. Not good, OS ripps apart and crashes, I have even seen it damage the elctronics on the RAM. When people try to mix.

    Really.......... and i suppose that all these mobo makers didn't think about that when testing out the boards....


    You're so smart... want a cookie?

    I have seen this happen, the motherboards that I have seen with dual type RAM state in the manual, whenyou bother to read it, that you must not mix the RAM.

    Whilst researching mine, a document from a link at Toms said if the board detects RAM fitted in the DDR slots it will use the DDR ignoring the regular SDRAM slots and whatever is fitted there. It only looks there if the DDR slots are empty.

    I haven't looked into it for a while, but I remember that DDR is actually faster than that of RDRam(rambus). I can't remember the exact details on it, but whereas ddr works typically at 266mhz it uses dual channels whereas rambus works at 700mhz (or something like that) but only uses one channel. I could be wrong as I said I haven't looked into it for a while, but there is somnething like that where rambus just uses the big numbers to make itself look faster. Which is no surprise as it's made from intel.
