    Hi;

    Would like to avoid possible compatibility issues between sticks of memory- can someone please comment on whether or not these two can coexist?

    *16MX64 SDRAM PC100-222-820 128M, SYNC, 100MHz, CL2

    * 128mb pc100 168-pin DIMM

    one's onboard, the other to be an add-on. information as written on the modules themselves-

    thanks very much for the assist!

    should work, but remember that some varieties don't play well with others.

    super...Motherboard, i genuinely appreciate the assist-
    thank you!

    BTW... The "CL2" which appears on the one and not the other is a reference to clocking speed is it not? Does it make a difference that's its absent from the one in terms of any compatibility issues?

    thanks again!

    They can co-exist, BUT .. it all boils down the to motherboard..
    There are couple of ways to see if the mobo will accept that configuration.:
    a. web site of the manufacturer..
    b. usenet ( newsgroups ) can tell if there is a problem with that particular configuration
    c. install the RAM and see ( can't go wrong , well it's not 100% proof , but ) .
    And to give better advice could you post the info about your computer? ( mobo make and model , chipset )

    point taken...i'm trying to avoid #3 though, if i buy it and it's n/g, i'm stuck with it- that's why i was trying to do the research in advance instead of just assuming that because they were both sdram and 100mhz they'd work-

    im also more than sure that if i were to ask compaq, they'd tell me i need "their" propriatary memory so id kinda like to avoid that discussion-

    i dont know if this helps, but the following is verbatim what's written on the "CL2" stick (non compaq);

    lable: HYS54V1622GU-S-C 16MX64 SDRAM PC100-222-820 128M, SYNC, 100MHz, CL2 C1W03011340 - does this help ID it any better?

    verify your ram type here

    thanks m'board...went to Crucial site as you suggested- not sure i used it correctly because there's really no apparent "substitution or cross reference list or replacemnt guide but there are live techs you can ask mon- thru fri- is that what you have in mind?

    What I had i mind was to enter the make of motherboard i the dropdown menu then go. In the next screen enter the model and it will show you the ram compatible with your pc..

    I think i see what you had in mind with this site, motherboard. It would work if i just wanted to find random compatable memory-where anybody's would be ok- but i have a particular stick (the first of the two initially listed) who's compatability i have to determine with the second- admittedly not the best way to sort out memory purchases- by cost only, but it comes down at least for now of being able to be certain that these two will work together- so what im really looking for is a cross reference or substitution list where a given mod # lists all the interchangable models that it will work with-

    E D I T ..............

    NOW I DIDNT CATCH THE MOTHEREBOARD- CAPABLE REFERENCE CAPABILITY- THAT I CAN DO- T Y!

    Well , in theory it should work..
    Like motherboard said, CL 2 is related to the "speed" it process the data. Basically RAM cames in couple of flavors
    CL3. CL2.5, CL 2 ( fyi --the lower the cl number the faster can the RAM "spit-out" the data, sorta of....:D ). Anyways , a CL2 RAM will work with a CL2.5 or CL 3 for that matter. Since it's able to "spit" out data, at a slower rate. On the other hand a Ram stick labled CL 3 or CL 2.5 will have a hellava time trying to "spit-out" data in CL 2 mode ( frankly , most <but not all > RAM sticks labled CL 3 will not be able to run CL2 ).
    Now webzter, how about posting what kinda of pc you have , again that way it take out the "guessing " out of the equation...

    sorry active95, et all.....pc i was refering to isnt my day to day but set to the side and in pieces ready for upgrading....

    it was suggest that i run the crucial "Belarc Advisor" which requires that the pc be whole so a diagnostics program can be run to determine the pc's inners- so i had to put the thing back together so i could run the program that would read the motherboard and tell me/answer me as to the compatability info im attempting to secure in order to know if a particular stick of memory id like to purchase will coexist with what's already installed.....

    turns out the answer that the program spits-out refers only to crucial brand memory (keeping in mind the program is offered by crucial on crucial's website- funny that!)to use and nothing about "will brand A work with Brand B".. so im still clueless at this point and need to know if the two above mentioned pieces of memory equals a usable 256mbworking TOGETHER!

    AS FOR THE PC IN QUESTION.... as i said, not my day-to-dayer....
    its a very vanilla/basic Compaq IPAQ C500 (celeron, regretably) 10GB hdd, 128mb, etc i can dig-up the entire spec sheet if that would help or provide a by-section break-out of any detailed area of the pc that would help as well-

    sorry again for the delay, but as i said, needed to put it back to gether again- (and it still works, too!)

    thanks very much for your patience as well as your time and interest!
