x86 vs x64 RAM Capacity.

As some might know i have a Viao VGN CR220e which has a max RAM cap of 4 GB. Supposedly 4GB RAM or less is meant to work with x84 systems but since i have a x64 bit Vista installed does that mean that i can install more RAM? than the listed 4GB max?

No, it does not mean that you can install more than 4 GB of RAM in the old Vaio laptop. That is a hardware limitation. The fact that Vista Home Premium x64 could support as much as 16 GB RAM doesn’t mean that your laptop could support it.

If you just want to surf the net with Firefox 52 x86 on vanilla Vista until the Vaio kicks the bucket, then I would suggest Vista x86. On the other hand, advanced users who want to try the extended kernel need to be running Vista x64.

I see thanks. It needs to be supported by both. So why would it be better to run x86 instead of x64 on my 4GB laptop?

Why would it be better to run Vista x64 with only 4 GB RAM and x86 browsers? But you can certainly do whatever you wish.
