32-bit vs 64-bit

just found this out my self, well at least one of the difference's, 32 version will only reconise around 3.5gb of ram so if you want more then that its going to have to be 64

as for any other differences i dont know!

there are some finer points to it, there is a link kicking around, but essential the maximum 64bit can use is 128GB (i think). its all about running out of addresses for your memory.
 
"Exabytes"
Is that a real word? :|

Also 64-bit applications run faster than 32-bit versions of the same application is what I heard.

More like 17,179,869,184 GB or 16 Exabytes. ;)

didn't bother doing the maths, so just went did a quick Google of what vista 64bit can do.

isn't it 2^64 = 18446744073709551616 bits or 2305843009213693952 bytes. , or am i mistaken/A live physics was a long time ago.
 
will i be ale to run all my 32-bit progs in a 64-bit OS even if they're not 'optimised'?
 
I still don't have the bottle to make the jump to 64. Sure I bet all the programs I currently use will support 64-bit but who knows whether all future programs that I need will work fine as well :)

Are there any signs out there that some games won't work in 64-bit (especially older ones)?

You shouldn't worry about programs going forward working on 64bit. Most games will work in 64bit as well (again you might need to check if there's a specific title you want to play) but 16bit games won't work, unless you use some form of emulation.
 
I'm on 64bit vista here.

No crashes (that wasn't caused by my self), fast load times and numerous other reasons.

Would never go back to 32bit. Get 64bit.
 
my only quarm is no fully working mkv 64bit codec for 64bit media centre

for this reason i'm changing back to 32bit for the time being on my media centre pc

ALL my other software works fine
 
Vista 64 bit here, all my games work and everything generally runs better under 64bit. It's noticeably snappier in my eyes, coming from XP as well. Make the jump, 64bit is *** future!

Exactly the same here. This is pretty much the only issue I have with Vista 64bit.
 
I'm on Vista x64 too. The only issues I have are that my USB scanner won't work (no drivers) and I haven't worked out how to access my work VPN (Cisco client) yet. Neither of these are problems though as I just run Windows XP in a virtual machine - means I don't need to mess around with dual-booting or anything like that.

Everything else, including most of my many many games, runs quickly and stably. The OS is rock-solid and I wouldn't go back to anything else now.

Yes there is.
I use Vista Media Centre (64bit) and all my MKV files work flawlessly..!

If you get stuttery video then just set "Noise Reduction" to 1 in your graphics card options.
Nvidia's option is located in Video & Television --> Adjust Video Colour Settings --> Enhancements
 
People who use Virtual Machines in x64, do you use MS's Virtual PC?

After upgrading to SP1 for Vista x64 I installed Virtual PC and after a reboot a couple of weeks later I found the Virtual Network Service Driver kept BSODing the machine over and over.

It was only after managing to get in to safe mode that I could disable the driver and boot properly to uninstall Virtual PC, the machine hasn't been the same since and I intend to do a rebuild this weekend.

I thought it was probably an incompatibility with Vista x64 SP1 and Virtual PC but maybe not?

I've got Virtual PC running on Vista 32bit SP1 fine just x64 that seemed to be a problem

Thanks
