Vista 32 or 64 bit?

Hello,

this is a rather stupid question probably...
I ordered a HP8510p with Vista Business . It is written that during the first boot-up, I will have to choose between a 32- or 64-bit version.
So...which one??? What are the advantages vs. disadvantages? Does most of my old 32-bit software run in the 64-bit environment?
I plan also to upgrade to Vista Ultimate.
I also read in another thread that you can dual boot both versions (or even triple boot with XP). Can i do that? (would be great ;-))

Thanks and sorry for the basic question. I couldn't find a thread like this in the forum, i hope i don't repeat a question from the past.

Here's the general rule: If you have to ask, you want 32-bit. Only use 64-bit if you have a specific reason to - you have 4GB of RAM, for example, or use (or will be using) a lot of high-impact software that has 64-bit versions. I have 64-bit Vista on my T61, because it has 4GB of RAM and will be used frequently for my engineering classes. 64-bit Vista will run the vast majority of your 32-bit applications just fine, yes, but some programs may not behave well. For instance, I have a rather irritating issue with FireFox hanging periodically that I don't have on my desktop, where I use 32-bit Vista.

 

Be assured that this is not a stupid question. There is a change of technology over time and questions will be raised.
The only advantage (currently) is that it runs marginally faster and supports huge amounts of RAM. No desktop/notebook system uses 128GB at the moment.
I have used both 32bit and 64bit versions of Windows Vista, and it largely depends on the types of applications that you plan to run on the OS. Naturally, 32bit Vista leans towards the best compatibility, assuring that every software can run (assuming that is is compatible with Vista). 64bit have an generally good compatibility, but specifc applications not designed for it may fail.
If you are unsure which to use, i suggest 32bit Vista.

Hello,

thank you so much for your QUICK answers!!
I just read that i could somehow make a dual-boot for both versions or even a triple boot with XP. Is that possible?

Generally my applications may be 64-bit ones, I am engineering student (PhD. in microwave electronics), and there are some simulation tools with 64-bit versions. I'll have "only" 2 GB RAM though. (I thought to upgrade to more RAM when it becomes necessary and cheaper.) My Processor is a Dual Core 2.4 GHz (Centrino enabled).

Thank you very much once again!

Yes, it is possible to triple dual boot Vista 32/64 and triple boot Vista32/64/XP32 (triple boot will need a little work).
I think you might want to check with the person in charge if the applications required for the course is available in 64bit before making the final decision.
64bit optimised programs will perform better in 64bit OS.
Cheers!

 

Hello,

thank you! Can i just use the same license for that? I only have the Vista coming with my laptop, no other CD. I read i have to install first the 32-bit version on one partition and then the 64-bit version on another partition. Is all that possible just with the Vista equipment i will get along with my laptop (HP8510p, Vista Business)?

Sorry if I order Vista Home will it ask the same 32 bit vs 64 bit question? (Dell Vostro, Core 2 Duo)

I use Windows 2003 x64 at work and no serious difficulties. As with all operating systems if the drivers work everything else works.

 

For what it's worth, if you are successful in installing your main apps on the 64-bit version, the only time you'd ever go back to the 32-bit version would be for compatibility issues. Although subtle, there a lot of small performance gains with the 64-bit version that combined, tell me I will never look back to 32. Your mileage may vary, but if your situation will alllow it, 64-bit is the way to go.

I'm an engineer myself, but I think anyone with enough patience and reasonable understanding/technical skills would be able to make the migration with little to no issues.

Good luck.
