This is likely to be VMS version dependent. I will try to look this up, but V5.3 is very old and may not support the full 512MB. Realize that the VAX 8700/8800 was the first to actually be able to have 512MB of real memory. Prior to that, I'm not sure if the hardware structures could handle "real" memory sizes over 128MB. Stay tuned. I'll look up in the release notes (I think I still have them.)

I Have the problem with OpenVMS 7.3. I can increase the memory to 128m or 256m or 512m, I see it on autoboot vax console, but looks like VMS does not recognize it. The show memory always tell 64M. Just for sure if I decrease it to 32m, then I show 32M on show memory result.
Remark: The PHYSICALPAGES default value is 1048576 and the current is 131072.
The PHYSICALPAGES system parameters controls the useable physical memory in OpenVMS VAX. Consider to run AUTOGEN to get the correct value set for PHYSICALPAGES or increase the parameter yourself with a conversational boot.

malmberg December 12 2017 HPE only makes the most current version of OpenVMS Alpha / IA64 /VAX available to hobbyists. When I had access to the Alliance 1 program it was the same. No public downloads are allowed by HPE.

malmberg September 10 2017 https://sourceforge.net/p /vms-ports/wiki/VMSInstal lation/ For the most part just use VMS 6.1 media instead of 7.3. But why run the older release?
DoeveR August 07 2017 Where can I find the write up on running VMS 6.1 using the simh emulator?
