Hi.

Finally getting round to installing Windows 7 but i'm not sure which disc to use 32 or 64 bit.

I am installing onto a Dell Lattitude D430 1.2ghz 2 gig of ram and Intel Core 2.

Any ideas

Thanks

There is a lot of this at the moment on the forum!!

To be honest, 64 bit will be better if your processor is 64-bit, however, if you have some older hardware, it may not be compatible.

After saying that, 32 bit is compatible with alot more so maybe it would be advisable to stick with 32 bit. Like I have after returning a 64 bit laptop!!!

Thanks - seen some of the forums and its looking like the 32 bit would suit. I'm only using it to surf the net and run office so no games or anything memory hungry

32 will suit you fine. Are you upgrading from Vista or XP?

I would do 32-bit, the only reason I have 64-bit is because windows will not recognise more than 4gb of RAM in 32bit and I didn't fancy losing 50% of my memory

Of course if you have a dual core or better processor then 64 bit is supposed to be better performance-wise

If you are only doing basic, routine stuff and have less than 4gb of RAM then I would go for 32bit, there is less hardware and software issues under 32bit

I'd stick with 32 bit, there's little performance benefit with less than 4GB ram and at 2GB ram performance could be worse under 64 bit to more memory being required, there's also more possibility of compatibility issues.

Isn't it a maximum of around 3GB RAM that windows 7 32bit supports? I have 4 gigs but when I go to system properties, it says it's using 2.93gigs

It's a maximum of 4GB total memory, but that includes everything (such as the memory on the graphics card) so your system memory may well be less.

Yer, my windows 7 32 bit installation says it only uses 2.99GB - This is something I think should have been sorted out, why cant they use more ram??!!

Typical thing with operating systems they are too busy trying to be the best and race ahead of themselves before perfecting what is current!!

In short they have already fixed it, Windows Vista/7 64 bit can recognise and use more than 4GB ram as can other 64 bit versions of operating systems.

The memory limitation is inherent to the 32 bit memory architecture, there is only 4GB of total addressable space which everything using addressable memory space must fit into leaving a lower maximum limit for the RAM. There are systems which allow a 32 bit operating system to use more than 4GB ram which mainly servers have been using however these techniques come with their own various downsides. With 64 bit hardware now readily available and decent software compatibility if you want to use more ram, change to a 64 bit OS.
