    PC66 vs. PC133 RAM

    I'm looking over a friend's Gateway PII, trying to figure out what makes sense to do with it. It currently has a single 64 MB RAM module, and two unoccupied slots. Crucial doesn't make PC66 RAM anymore (which is what their scanner says it takes), but Kingston has them for $35/each. TigerDirect has PC133 modules (also SDRAM) for $18/each. Should the TigerDirect modules work--even if it means I would have to remove the existing 64 MB module?

    John,
    I would be a little "leery" of using the PC133 in place of the PC66. Most times 133 will work OK but run at the slower speed of the 66. Notice I say MOST times.
    There is still a lot of PC66 RAM around for sale if you do a little shopping. For example, THIS SITE
    They have 64mb @ $9.00
    128mb @ $12.00
    256mb @ $28.00

    I would give them a call at their 800 number and give them the model number of the machine and they should be able to verify compatibility.
    Depending on the number of spare slots on that motherboard, you can pull the old 64mb stick and replace it with a couple of the other with larger capacities. They simply add on to each other for the total amount of RAM installed. ( two 256 sticks give you 512mb )

    >> 128mb @ $12.00 <<

    I've never bought RAM from anyone except Crucial (directly) or Kingston (from my local parts supplier) but I'm willing to give these guys a try. The Intel mobo in this Gateway supposedly can't take anything larger than a 128 mb stick, so the most I can do is 384 total. Would what these guys call Low Density be what Kingston calls SDR (which I assume means Single Density RAM)?

    Probably, but give them a call at 1-866-242-5523 to make sure.

    BTW, 384 is a lot better than only 64mb!

    Hi JJ,

    AFAIK SDR = Single Data Rate, as opposed to DDR (Double Data Rate)
