Win 2012R2 VM server is not displaying RAM correctly in server manager

Posted on 2016-10-13
Last Modified: 2016-10-22
I'm running a NEW VM of win 2012R2, 64bit.  When I check the properties under "this PC", it shows the 113GB.
When looking in Server manager, it shows only 3.88GB.  I am using fixed RAM.   I tried dynamic ram and it did work,
it actually showed 8GB, what I set it to.

So why is the fixed ram not working correctly?  Since this server will be a SQL box, I was thinking using fixed will be better or faster
for the server, but it does't look like it's going to work.  

Any thoughts how to fix this?

Didn't you just close this question? If this is still an issue, why?

As I asked before, have you patched both host and guest *and* rebooted both host and guest?

Yea, I thought it would have resolved the issue.  I'm installing all the updates.

One of several post-RTM fixes. Thus the patching request in both questions.

Yes, I'm using Gen 2 vm. I'll install the hotfix

David Johnson, when I run the file, I get the error "the update is not applicable to your computer"

Just so you can see I'm not crazy, under properties, it says it's a 64bit OS installed.
The file gen2 hotfix is also 64 bit, so I'm puzzled.

I did a test and when I changed the RAM to 8GB, it shows up fine in server manager.

when I tried 96Gb, it did not recognize it.  So somewhere between 32GB and 96GB it has an issue

its official, it's a BUG in the OS.  I just assigned another VM the same amount of ram, 115GB, and that VM does the same thing, it only displays 3.88GB.   So with all the updates installed, I guess MS has had over 2 years to fix this issue, but  has NOT.
