Remember when….
With so many people making the move to windows 7 for reasons that include upgrades in their CAD software I thought I would address some of the common things I am seeing and hearing. I have heard conflicting reports on if you should move to a 64-bit Operating System (OS) or not, and for the most part my answer is YES!
Windows 7 comes in a 34-bit version as well as a 64-bit and as I found on my new laptop you have to specify which version you want. I thought by selecting Windows 7 Professional it was a given, but now a month and a half in I just realized that I was sent the 32-bit version. The upgrade if you catch it early is an easy re-install. For me at this point it means I have to start over again which I am not ready to do today.
To verify your version click the
button then select CONTROL PANEL. Once you are in the Control Panel, click the system and security option
. Once here you can click the SYSTEM option to see information about your system including the system type (32-bit or 64-bit).
Now why does it matter if you have 32 or 64-bit?
Memory, memory, memory.
| Version | Limit on Physical Memory 32-bit | Limit on Physical Memory 64-bit |
| Windows 7 Ultimate | 4 GB | 192 GB |
| Windows 7 Enterprise | 4 GB | 192 GB |
| Windows 7 Professional | 4 GB | 192 GB |
| Windows 7 Home Premium | 4 GB | 16 GB |
| Windows 7 Home Basic | 4 GB | 8 GB |
| Windows 7 Starter | 2 GB | 2 GB |
If you are working on with large images, scans, Lidar or any other large data set this will make or break your production. Make sure you get the 64-bit of Windows 7 if you want to take advantage of all of that memory you purchased.
