Maximum System Memory Support?

» close window

The Question is:

Mr. Wizard:  We would like to upgrade the memory in our DEC Personal
 Workstation 433au.  Many sources indicate that this system supports up to 1.5
 GB of memory.  However, the Compaq/DEC System and Options catalog from Jan
 2000 says that memory for this sy
stem is limited to 1 GB under VMS (1.5 GB is supported under Windows NT and
 Unix).  Is 1.0 GB really the limit under VMS, or has this limit been removed
 with recent VMS versions?

The Answer is :

  In general, OpenVMS will support the maximum memory that the Alpha
  box will itself support.
  OpenVMS Alpha V7.1 is very old, and does not have support for the
  -au series, you will want to use V7.1-2, V7.2-1, or V7.3 or later.
