Ur processor architecture should be x64-64Bit

everything is fine but u will need gfx card perhaps for vista aero system ..else u can install and use it peacefully
xp_64 bit will work fine ..

Ur chispet - 946GZ supports 64 bit computing and all the C2Ds are 64 bit proccies.
In Short ur system is 64 bit system but installing a 64 bit OS makes sense only if u have ram more than or 4 GB.
64 bit system means that the address and data buses are 64 bits wide and u can access(theoretically) 2^64 bits ~ 128 GBytes + of ram and thats insane amount of ram!

^Exactly !

shortest answer: works
no its not needed its just that if RAM is more than 3Gb it doesn't get recognized by 32 bit OS ...so if u have say 4GB RAM ...windows xp 32 bit and vista 32 bit will only recognize only 3 GB ...
but to run 64 bit u don't need 4GB works fine even with 1Gb RAM .. for vista obviously u will need 2Gb RAM to let it run smoothly ..

NOT NEEDED....... 4GB RAM requires 64Bit OS to work on full potential not the vice versa

both wrong actually. 4gig can easily be used by 32bit os, but with some hacksNOT NEEDED....... 4GB RAM requires 64Bit OS to work on full potential not the vice versa

^^I am talking natively.
And both are not wrong. 64Bit OS can work with 512MB RAM too

Consider 32bit OS as a subset of same 64bit OS.
even if u have 128MB ram winxp x64(Vista won't) will work fine but does not make any sense!
Since u will be using 3 gig of ram u can go with 64 bit OS - in case if u want native OS support to run 64 bit apps.
I think u must go for 64 bit OS for the sake of 64 bit apps!

U wont get real time speed & multitasking benefits with x64 until you are using 4Gb & above ram.
In x64 OS each software (assuming they are 32bit)can minimum use full 2gb ram, so the real benefit will be when you need to have 2-3 software making use of full capacity (2gb each)for which you would need above 4Gb of ram. Of course x64 will work in crawling mode on 512mb of ram (x64 Vista would require at least 2gb with a decent graphic card)
I run 3 application which are x64 & each one of them is capable of using full 4gb & above if available so thats the real benefit of x64.
Another things to consider is that you wont be running 3gb in dual channel mode, either it should be 4gb or 8gb (correct me if I am wrong)

with Intel Flex Memory u can use different memory sizes in dual channel mode so thats not the problem ...
and i did not understand ur 4Gb for 64 bit theory ..so far with 3Gb on 64 bit i don't face any problems

Good to know something new I was not aware of it.
X64 will work fine 1gb /2gb/3gb but you are not getting "much" real benefit with lower amount of ram.
Vista x64 OS in my case can hold & make use of 1.5gb of ram I can reduce the startup applications & bring it down to minimum 800mb of ram, so when i have 2 applications running & both using the dual cores & needing ram allocation, both the applications can use all the ram. That benefit is greatly reduced if you have 2-3gb ram bcoz then you can use it within a 32 bit system too , why do you need x64.
x64 is like having 128 pipes coming to ur bathroom to fill the bucket & if all those pipe will outlet water from a only 2-3 taps then u r greatly loosing on it, u r better with 2 pipes to start with.
Real benefit will be to have more outlet taps so u can fill a single bucket faster with multiple taps or fill more buckets together at the same speed /same time.
Hope the above makes some sense, I myself was confused to go x64 or not as I was hitting bottlenecks when multi tasking on 32bit then i had to read a lot to understand how to get maximum out of a x64 & now i can do multitasking (4-5 intensive task without any slowness)
I also tested a x64 vista 16gb ram (4gb x4 sticks & believe me it flies like a rocket when multitasking ) my next machine will have 12-16gb ram when photoshop x64 bit CS4 is launched. There are 7 application now which I need to use & they are x64 so they can use all the available (no 2gb limit) ram.
