4358.0. "512mb mem for VAX4700A?" by QBUS::E_BURKHALTER () Fri Apr 04 1997 14:36

    
    Is there a single module 512mb memory option
    for a VAX 4000 Model 700A?
    
    A field engineer says that he removed the
    original memory modules and installed a
    single 512mb mem option a few months ago.
    
    If there is such a module, I would like 
    to get the part number of the module and the
    +5 and +12volt load and the watts.
    
    I can find a 32, 64 and 128mb memory modules.

4358.1Probably Third-Party...XDELTA::HOFFMANSteve, OpenVMS EngineeringFri Apr 04 1997 14:553
   If a 512 MB MS690 variant doesn't show in our listings,
   it's probably third-party...

    I would assume third party also. 
    
    Just remember 512 mb is all you can put in anyway. A 512 mb memory card
    will appear to the firmware as four 128 mb cards. there is no support
    in firmware for memory above 512 mb. A 512 mb card would probably use a
    little less power and probably have a better mtbf assuming it is using
    larger ram chips.
