32bit 64bit help

[Vaharai]

At a command prompt type either
systeminfo
echo %PROCESSOR_ARCHITECTURE%

All modern CPU's are 64 bit. If you can install 64 bit windows it is certainly 64 bit CPU...
As someone already mentioned here with a 32 bit OS you can only use 4GB max.

As far I know, this command does not work.

32bit OS තියෙන පරිගණකයක් තියෙනවා මේක 64bit Support ද කියලා හොයගන්න බැරිව හිටියේ CMD Command එකක් හම්බුනා දවසක් ඒක ගහලා බැලුවාම ප්‍රොසෙසර් එක x86 කියලා ආවේ ඒ කියන්නේ 32bit නේ.

අද Windows 7 එකක් දැම්මා 64bit මන් හිතුවේ මගදී නතර වෙයි කියලා මේක Install උණා මේ cpu එක 64bit එකක් නිසාද Install උනේ ?

32bit එක්ක කොහොමත් 64bit Install වෙන්නේ නෑ නේද මචන්ලා ? 32bit එක්ක 64 Install උනානම් අවුලක් වෙනවද ?

Processor model eke spec baluwanan simple ne
cmd eke gahuwama pennanna aththe e welawe install karla thiyena OS eka bit keeyada kiyala. 64bit support nathi procek hoyaganna amarui dan.

Of course both commands do work....the latter being an environment variable.
If you’re on 64-bit Windows
C:\>echo %PROCESSOR_ARCHITECTURE%
AMD64

If you run the 32-bit (x86) Command Prompt,
C:\>echo %PROCESSOR_ARCHITECTURE%
x86

If you open a 64-bit Command Prompt on 64-bit Windows...
C:\>echo %PROCESSOR_ARCHITECTURE%
x86

Also there is another environment variable
C:\>echo %PROCESSOR_ARCHITEW6432%
AMD64

But with a 32 bit command prompt you get different results.

Read MS documentation on these variables for further explanation.

there is no use unless you have more than 4GB RAM.

Agree
