How to identify  Parity and Non-Parity.

    Non-IBM cards
    If you find figures like " 36M" or "36" other than figures indicating capacity,  it may be Parity memory.
    If you find figures like " 32M" or "32" other than figures indicating capacity,  it may be Non-Parity

    IBM cards  ( example  )
    Parity DRAM cards  are  *thick black*  while  Non-parity cards are *gray*. 
    There is no indications about Parity or Non-parity on the card. If you don't have FRU P/N handy, 
   identify cards by their color.

    Both models take Parity cards only.   Do not got for Non-parity DRAMS.
    Maximum capacity per slot is limmited to 8MB.  If you pop a 16MB DRAM card  in any slot, system will
    count to 12MB ( planar 4MB + half amount of installed card ) and then turn into reference. Auto-conig,
    save config then reboot, memory count will stop at 4MB and you'll get 163 and 201 error.
    TP720 can accept FUJITSU  FMBNEM81, CA46006-6256 parity memory. I think TP700/720 can 
    also accept  DJ-8M-QA( 4P.8L ) by MAXELL.

    As far as I can see, 5537 and  5538 can take both Parity and  Non-Parity memory cards 
    except 5538-Z.  I myself have not yet confirmed it.  At least 5537-ZAC can take both parity and
    non-parity .
    Some models have  " Parity check disable option" in Easy Setup Menu and others are designed to use 
    Non-Parity memory cards ( Of course parity card can be used as Non-Partiy memory. Parity bit of 
    such cards may just ignored by the system ).
