    PC 2100 SD RAM vs 100 Mhz SD RAM

    I've just junked a 13 month old computer with AMD Athlon XP 1500+ with Quantispeed Architecture and 512 meg, PC 2100 DDR SDRAM.

    I have an older computer with 400 MHz Intel Pentium II and 256 mb, 100 MHz SDRAM

    If I take the PC2100 DDR SDRAM from the junker and put it into the Pentium II machine will it function correctly?

    Or will limitations on the older motherboard architecture cause it to run slowly?

    Or, will it not work at all?

    You will need to check the spec's of this mother board to see if this different ram will work.

    Now running HP Pavilion a6528p, with Win7 64 Bit OS.

    By checking the specs... is this something I do by going to the manufacturer's site or is it something I would find on the board itself or provided in the scanty documention that came with the computers?

    "by going to the manufacturer's site " and looking for the model number of your mother board.

    Great; thanks!

    Would I be risking anything if I was to take the PC2100 RAM out of the clunker-on-its-way-to-the-landfill machine and put it into the older machine - just to see what happened?

    pc 2100 ram is 184 pin, and pc100 is 168 pin. Unless your mobo is set up to use both, with 2 different sets of sockets, (you can't use both at the same time, one or the other) it just plain ol' won't fit.

    sorry

    With the age of your PII I am sure you cannot use the PC2100. As previously stated it is 184 pins and your P II uses 168 pin socket. Also the "notches" on the memory sticks will be different. Finally, they are different technologies.
    Why did you scrap the AMD? <img src=/S/cool.gif border=0 alt=cool width=15 height=15>

    Thanks for the data on pin numbers. Looks like I have an extra 256 megs of PC2100 RAM!

    The AMD came with a unit I bought from MicronPC 13 months ago. The chip set fan went out on it 8 times! And the HDD went south twice. I finally got fed up with it and bought a Dell with a P4 - though I have 2 more years of warrenty on the Micron - when the tech supervisor at Micron said that the chip set fans are supposed to make noise like a jet aircraft! The chipset would make this noise for a few weeks before stopping altogether and causing the motherboard to melt down. Warrenties are wonderful things to have when things go wrong but I'm tired of the down time it takes to call tech support, get a replacement, wait for the replacemnet and then install it. So, I got a new computer for less than I paid 13 months ago [surprise surprise] and all is well with the world!

    Besides having RAM that isn't NOW compatible with your other machine, why just throw out out the one machine without "stripping" out some of the useable parts, like the RAM, power supply, AMD chip, HD's , etc.? You never know when you might need these components for replacements, testing or other needs in the future.

    I think most people who are "into" PC's all have a spare parts box (or boxes) for just those reasons. I know I sure do, and they come in mighty handy at times. <img src=/S/2cents.gif border=0 alt=2cents width=15 height=15>

    Yeah, that. Parts. If nothing else, you can sell them on eBay. I'm amazed at the prices people get. Many times it's a few dollars OVER retail new, NOT including shipping. I guess the auctioneering bug just bites people (ok I admit to a few teeth marks myself....)

    Re: PC 2100 SD RAM vs 100 Mhz SD RAM

    Speaking of parts, a few months ago I needed a new cable to install a hard drive. Despite the fact that I have in excess of 10 or so at home, at a major US national retailer I HAD TO PAY $24.95 FOR A HARD DRIVE CABLE because I live about 50 miles or so from the pc! I AM CHANGING UNDERWEAR AT THIS POINT!

    Save any parts you can from an old PC! It will come in handy sometime!

    I looked at a CD audio cable at CompUSA...same price. $24.95!!!! Can you believe that? (It had like 4 connectors at one end "universal") Needless to say I went home and tore apart the old box....
