32 bit vs 64 bit Vista question

2008-10-26, 3:48 AM

I ordered my W500 with 32bit Vista Ultimate because I read some articles on the web that not all the software vendors have full support to the 64 bit OS. Is this true? On the other hand I also heard that 64bit OS runs faster than 32bit. Is this true?

 

I am currently running Adobe CS3 on my XP Pro box with quad core. Should I stay with 32bit OS or I should call lenovo to change it to 64bit?

 

Any insight would be appreciated.

 

Shawn

it depends on the type of OS you are using if its a 64 bit OS then you can use 64 bit programs or else the 32 bit once can you give your system model so that it can be easy to say whether its a 64bit OS or 32 bit one?check out your documentation as well

The unit is still being built. I guess my question can be boilded down to these

 

If this system is a 64bit machine would I be better off using 64bit Vista?

I believe I ordered a 32bit version of Vista. If I should go with 64bit version what should I do?

 

Here is the summary of my system

Model W500 4058 CTO

CPU Intel Core 2 Duo T9400(2.53 GHz, 6MB L3, 1066MHz)

RAM 2GB PC3-8500 DDR3

 

Does this help you answer my questions?

your processor supports 64bit versions of vista as well the choice of selecting the architecture depends upon your needs and requirements

 

if you have brought a retail version of vista ultimate then you get both 64 and 32bit versions of the OS

 the advantage of 64 bit vista is that it can address more memory(32 bit versions support upto 3gb only)and provides more enchanced security than 32 bit versions

 

my only sujjestion is that if you are a graphics designer or have high end requirements you can go for the 64bit version for more info check out this link

Not true, they support up to 4GB of RAM but the limitations imposed on address space cause you to lose some of the RAM to addon cards.  In essence you usually don't see more than 3-3.5GB on most machines, and less on others.

 


and provides more enchanced security than 32 bit versions


Not sure what you mean here, other than the fact that all drivers on Vista x64 MUST be signed, whereas 32-bit can run unsigned drivers.  Otherwise there's nothing really "enhanced" about security on x64.

 

To the OP:

The way to answer your question is to look at how much RAM you are putting in and the other equipment you're throwing on the machine.  If you are doing more than 2GB and you've added TurboMemory or a WWAN card, you're probably better off running x64 Vista in order to see and utilize all of your RAM.  You may run into occasional compatibility problems with older programs - 16-bit programs DO NOT RUN on x64 Vista.  Most of the time this isn't a problem, but even some programs that are actually 32-bit (which runs fine) use a 16-bit installer (which won't run).

 what i was refering to was this:
 

One of the primary benefits of using an x64-based version of Windows Vista is that these versions provide somewhat improved security functionality when compared to their 32-bit counterparts. Working in tandem with the No Execute (NX) technologies in modern x64 microprocessors from both AMD and Intel, Windows Vista x64 versions, like XP x64, also provide support for hardware-backed Data Execution Protection (DEP), which helps to prevent the buffer overflows that are commonly used in electronic attacks. (32-bit Vista versions utilize a less effective, software-based version of DEP.)

Another unique x64 feature, Kernel Patch Protection (sometimes called PatchGuard), prevents malicious software from patching the Windows Vista kernel. PatchGuard, Microsoft says, works by preventing kernel-mode drivers from extending or replacing other kernel services and preventing third-party software from patching any part of the kernel. 

 i think this will give you the insight you need  :D

I am a graphics designer not a hardware/security guy so I found your answers were little too in depth to understand. I did talk to lenovo support person and he recommended that I should go with 32 bit for hardware compatibility benefit. I raised my concern that I might not be able to use more than 3G of memory when I upgrade in the future. His answere was that I got a good machine and maynot find any problem with 2G (that is not a very good answer to me).

 

Anyways that was the update.
