Windows 7 - 32 or 64 bit?

Found 28th Nov 2009
Gonna install W7 Home Premium on my Sony Vaio to replace Vista.

Done the compatibility upgrade advisior, which I downloaded (only my Canon MP210 isn't compatible).

Now my only decision is do I go for 32 or 64 bit? Currently only have 2GB RAM, but wanna upgrade to 4GB.

Just wondered which if any is better and the differences?

32 Bit because it can see up to 4gb on W7

32 Bit because it can see up to 4gb on W7



Umm, no it cant.

Stick to 32 bit honestly.

More trouble than worth the 64 bit is.

Just to throw a spanner in the works I'm running 64 bit Windows 7 on 4Gb of RAM and it works flawlessly on both 32 bit and 64 bit apps.

Also, if you have 4gb of RAM then you must choose 64 bit as 32 bit Windows cannot address more than 3gb of RAM.

Obviously your CPU has to support 64 bit...

One thing I found with the 64Bit is the printer support, and some of the older hardware. I havent had an issue with any off the applications though.

Could that be general Windows 7 compatibility as opposed to 64bit vs 32bit?

I've been lucky as all my hardware has been ok, I've obviously had to substitute WIndows Vista drivers where 7 driver do not exist, but most modern machines that run 7 have modern peripherals and so the manufacturer usually still offers support and new drivers for said equipment.

32bit will see about 3.6Gb of the 4Gb if you upgrade the ram. 64bit will see the whole 4Gb. 64bit will run 32bit apps, but they may run slower as it has to run via the 32bit emulator. If you are gaming with the machine, then I would recommend 32bit for ease and speed.

By the sounds of it some peoples last experience of a 64-bit OS was Windows XP. You shouldn't have any issues under 64-bit Windows 7 that you wont have under 32-bit, unless you have some antiquated peripherals. Some 32-bit apps might be a fraction slower (unlikely to be enough to actually notice in the real world), but everything is going 64-bit these days so that problem wont be around for long. Google it, the consensus is that "64-bit is going mainstream".

That said, you haven't actually stated whether you have a 64-bit processor or not.....

When I had 64 Bit Windows, my Canon LBP5000 Laser printer would not work. Not supported by 7 or Vista 64 Bit OS.

And 4 VS 3 GB made no difference at all in my opinion.
