    What is the best memory 512 for a CF-28 800MHz (512) and cf-m34 ( 192 RAM)

    (I think it is also known as a MK2, or are
    there MK1, 2, and 3 models for each CPU speed?)

    I have already tried one type with my 800GHz CF-28
    and it failed.
    NOW IS 256 + 256...question: FROM 512 TOTAL to 768.. performance is minimal or best??

    bios v200L12l ..IS THE LAST ..??upgrade or ok ??

    have you for sale?? (PM..)

    regards

    There are a couple of threads around that explain what the best type of RAM is... Check the CF-28FAQ...

    There is very little difference in perfomance between the 768 and the 512.

    For the MK2 the latest version is V.00013... Again... You can check the same place for a download link to get the update.

    I bought one of the recommended ram chips and my CF-28 will not even boot with it installed - the word is that the BIOS is extremely temperamental when faced with a 512M chip/card and one may have to try several to discover one that works in a specific machine.

    YMMV ... ;-)

    There are many prople who have gotten the 512 RAM to work in the CF-28. SOME of the 1Ghz units are really the only ones that are suppose to work with a total of 768MB according to Panasonic. It really is a crap shoot to see if it will work on yours. I know that it WILL NOT work on a Mk1... It might work on SOME Mk2s and on most Mk3s...

    No harm in trying... You can always throw the extra RAM on ebay or use it in a different laptop!

    Does anybody have a 512 module part number that works? in the CF-28?

    I have a P3 1000Mhz machine with 256 on board. Tried a PNY 512mb pc133 sodimm but it didn't work. I have a kingston chip on order part number

    KVR133X64SC3/512
    PC133 SDRAM 144-Pin CL3
    SODIMM Memory Module

    Hopefully it will work

    It looks like it should... best I can do. it has the 4 chips on each side which is what you look for. But I've had 512 sticks with 4 chips on each side that fail boot! You won't know until you try...

    Take another look at the memory module pictured. Doesn't that say "200" at the top, as in 200 pins?
