[comp.sys.dec] VAXstation Memory Upgrade Problem

schmidt@sysjj.mdcbbs.com ( Allen Schmidt ) (05/23/91)

 Here's the situation:

   We have 2 VAXstation 2000's that we recently bought 3rd party memory for to
   max them out at 14 Mb ,we are having a problem getting one of the stations
   to recognize all 12Mb on the board. 

   TAC1 = VAXstation 2000, Satellite in LAVC. Has a local RD54. Running VMS
   5.3-1. Originally had 6 Mb ( 4Mb + 2 Mb resident ). Swapped out the	  4Mb
   DEC board and installed a 3rd party 12Mb board. Booted the system up, did
   show memory and there is was 14mb.

   TAC2 = VAXstation 2000, Standalone system with RD54 and TK50 in an expansion
   box. Running VMS 5.4-1. Same memory config as TAC1. Swapped out the 4MB
   board, rebooted the system. When I do a show memory, only 4Mb show up. Had
   our hardware FE do the installation and he was at a loss as to what is going
   on. He ran diagnostics, negative.  

   If anyone has run into this before, or has any
   ideas/hints/suggestions/words_of_wisdom reagarding this problem i would
   appreciate any and all.

You have older PROMS on the mother board.  I forget what version you need, but
if you call Atlanta they will be happy to tell you.  I had this same problem
when I first got my expansion board for my VS2000.  Atlanta was even able to
tell me the part number so that my FSE could get it and install it.  Of course
putting the VS2000 back into the box was a little troublesome for him - he has
broken the halt switch on three motherboards and still hasn't gotten me a 
working one, but that's another story.
