Mike Castle posted the following interesting solution to display the amount of physical memory in NT.
It uses native NT commands only.

I have used this idea to create a batch file, GetRAM.bat, that displays the amount of RAM on the local NT 4 system:
@ECHO OFF
:: Enable command extensions and save initial environment
VERIFY OTHER 2>NUL
SETLOCAL ENABLEEXTENSIONS
IF ERRORLEVEL 1 (
ECHO Unable to enable command extensions
GOTO End
)
:: Check parameters
IF /I [%1]==[] SET SWITCH=/V
IF /I [%1]==[/Q] SET SWITCH=/S
IF /I [%1]==[/S] SET SWITCH=/S
IF /I [%1]==[/V] SET SWITCH=/V
IF [%SWITCH%]==[] GOTO Syntax
:: Use WINMSD.EXE to check the amount of RAM installed
START /W WINMSD.EXE /S
:: Read the amount of RAM installed from WINMSD's report
FOR /F "tokens=2 delims=: " %%A IN ('TYPE %COMPUTERNAME%.TXT ^| FIND "Total:" ^| FIND /V "\"') DO SET RAM=%%A
:: Delete WINMSD's report
DEL %COMPUTERNAME%.TXT
:: Add 1023 to round up, or
:: add 512 for "mathematical" rounding, or
:: add 0 (or "rem out" next line) to round down
SET /A RAM = %RAM:,=% + 1023

My own solution to the same question on alt.msdos.batch.nt was to use PSTAT.EXE from the NT Resource Kit)
FOR /F "tokens=2 delims=K " %%A IN ('PSTAT | FIND "Memory:"') DO SET MEM=%%A
:: The following command line determines the rounding method.
:: Add 0 to round down, 1023 to round up, or 512 for "mathematical" rounding.
SET /A MEM = %MEM% + 1023
SET /A MEM = %MEM% / 1024
The result was Memory.bat. It is much faster (PSTAT.EXE does not check hard disks, as WINMSD.EXE does), it does require the NT Resource Kit, whereas GetRAM.BAT uses native NT commands only.
@ECHO OFF
IF [%1]==[] GOTO Begin
ECHO.

ECHO GETRAM.BAT is based on an idea posted on alt.msdos.batch.nt by
ECHO Mike Castle. It uses NT's native WINMSD.EXE instead of PSTAT.EXE
ECHO from the Resource Kit. However, it is much slower than this batch
ECHO file.
ECHO GETRAM.BAT is available at http://www.robvanderwoude.com too.

ECHO Total installed RAM in MB:

:: The following command line is added to round up instead of down;
:: change the value from 1023 to 512 for "mathematical" rounding,
:: or remove the line to round down
SET /A RAM = %RAM% + 1023
