519.5Mixed SIMM density install help pleaseJULIET::HATTRUP_JAJim Hattrup, Santa Clara, CAWed Feb 12 1997 20:3325
    
    Customer has 2 64MB options in their AS 1000  4/233 (Digital UNIX),
    for a total of 128 MB. 
    
    They just purchased and installed an additional 128MB (PB7MA-AD option)
    as a single option (5 SIMMs).
    
    However, the system only sees 192MB (incremental 64MB, not 128MB).
        instead of 256MB.
    I thought they installed the new SIMMs in bank 0 (presumably moving the 
    64MB that was there to bank 2).
    
    1. If they installed the new SIMMs in bank 2, would they only see an
    incremental 64MB?
    	2.  If they installed the new ones in bank 0, is there anyway they
    	would see only 192MB total (vs. 256MB)?  perhaps reinstalling the
    	the 64MB SIMM set some bank greater than 2?
    
    Are the AS 1000 banks 5 SIMM slots together - or do the parity SIMMs 
    get installed elsewhere (I'm wondering if the parity SIMM location
    caused this).  I do not think we shipped install instructions with the 
    PB7MA-AD kit the customer ordered.
    Thanks.

519.7Swap SIMMs till we see 256MB....JULIET::HATTRUP_JAJim Hattrup, Santa Clara, CAThu Feb 13 1997 21:456
    Re: .6 
    Thanks.
    
    The Digital service engineer believes one (or more) of the 32MB SIMMs
    is bad.  We are going to install some replacements and see if the
    problem goes away.
