Create Your Own Psuedo-RDRAM

" Having the same sentimental attachment to my RAM that most people do, I haven't even attempted this either - anyone know if this works, even in theory? Post below. [Updated 28th April by timothy:] Well, this won't actually convert your SDRAM to RDRAM of course, but it will add to your heat-slurping overclocking abilities.

  1. Umm.. What? by Defiler · · Score: 5

    This article has NOTHING to do with turning SDRAM into RDRAM.. All they did was put a copper shield on a stick of SDRAM, making it look similar to a real RDRAM module.
    Doesn't Slashdot occasionally GLANCE at the links that are submitted before posting them?

  2. Thanks for the link Hemos! by Skinka · · Score: 5

    This comes in really handy as I just converted my 16MHz i386 to 1.5GHz Willamette, which as we all know doesn't support SDRAM for now. Now if could just convert that 5.25" floppy drive to a DVD-RAM drive...

  3. Not really... by toastyman · · Score: 5

    I know a few of these points have been brought up already, but let me summarize and add my own thoughts:

    1) The metal bracket on RIMMS isn't for EMI shielding, it's for heat. It's just like the heatsink on your CPU, which doesn't add to the EMI protection noticably.

    2) A 150MHz SDRAM dimm isn't RDRAM. Rambus uses an entirely different protocol, and anyway... 150Mhz SDRAM is probably faster than rambus.

    3) Your SDRAM won't work at 150MHz because it's simply too fast for the junctions to switch, not because of EMI. If you've got a serious EMI problem, you'll probably see it if you're overclocking or not.

    4) That design shown probably wouldn't fix an EMI problem, either. It'll most likely act as an antenna, worsening the problem.

    BUT... To whoever made that page.. Keep hacking. While this idea might not have worked, you may come up with a great supercooled DIMM refrigerator or something. Good luck. :)

  5. How did THIS get posted??? by -brazil- · · Score: 5
    The poster apparently has no clue whatsoever. The article is NOT about turning SDRAM into RDRAM, which is utterly impossible since the technologies are radically different.

    This article merely tells you to make an SDRAM module look like and RDRAM by giving it a shield agains electromagnetic emissions. This might have some benefit in very rare cases, but realistically, it's totally pointless.

  6. UHHH, NO by EK-Hack · · Score: 4

    That page was about reducing EMI in your ram in case you are overclocking your system, not converting SDRAM to RAMBUS. They just mention in the beginning why RAMBUS has the shielding.
