Windows 7 Upgrade Advisor Question

By joesewi ·
When I run Windows 7 Upgrade Advisor I get the message that I can upgrade to Windows 7 32 bit edition. I am running an Intel 2 core CPU, 2G of ram and Vista Home Premium 32 bit. I get a 4.8 on the Readiness Analyzer for Windows Vista. If I do a custom install will I be able to run Win 7 64 bit OS?

But the limits will be due to your motherboard.

Motherboard / Chip-set

by TheChas In reply to Windows 7 Upgrade Advisor ...

You first need to take a look at your motherboard specifications. Including the chip-set and how it is implemented.

Even though you may have a 64 bit capable CPU, if it is mated to a chip-set that implements a 32 bit system, you will not be able to install and run a 64 bit OS.

One quick test is what is the maximum amount of memory that you can install on your motherboard. If the answer is 4GB or less, the chip-set and BIOS most likely only support a 32 bit system. If you can install 8GB or more total RAM, you may be able to run the 64 bit version.

Keep in mind that the setup advisor might be looking at available RAM. As 2 GB is the minimum for Windows 7 64 bit, if you have on-board graphics that uses shared RAM you may not have enough free RAM for the Windows setup advisor to determine that you can run the 64 bit version.

If your system can support a 64 bit OS, I strongly recommend that you add more RAM before you install Windows 7. My general rule of thumb is that you should double Microsoft's minimum requirements if you want your computer to run smoothly.
