Hi my name is paolo I'm pretty much confused about the 32 and 64bit specification. I'm confused if it is the CPU or the Motherboard.
First I tried to see if my CPU is 32 or 64bit. Ive seen a site that gives a few easy steps to determine if my CPU is 32 or 64bit.
#1 Go to Start -> Right click on Computer -> Click Properties. Click on Windows Experience Index ->View and Print detailed performance and system information.
mine shows like this.
System type 32-bit operating system
Number of processor cores 2
64-bit capable Yes
(Q: would this tell that my CPU is 64 bit and I'm just using 32-bit OS? or I just really got a 32 bit CPU? )
#2 Go to Start -> Type regedit
Browse to HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
they said : From ProcessorNameString you will be able to see the name of your processor and from Identifier you will see the family of the processor and if it has 64 then it is 64-bit capable.
Name: Intel(R) Core(TM)2 Duo CPU E4500 @2.20Ghz
Identifier: x86 family 6 model 15 stepping 13
(This one actually conclude that the cpu is 32-bit)
#3 Go to Start -> Type msinfo32.exe "System information"
check System type.
mine is x86-based PC
(Q: Is this x86 based PC is really identifying the CPU or the Motherboard? when i search on how to check if motherboard is 32 or 64bit this is what they do. So now I'm confused if it is for CPU or for Motherboard?)
they said: Under Instructions from CPU tab, if you see EM64T (if its Intel) or AMD64 (if its AMD) then your processor is 64-bit capable.
I got EM64T which they said is 64-bit capable.
(Q: WHAT THE!! #1 I'm not sure, #2 and #3 said that my CPU is 32-bit but #4 said it is 64-bit please help me I'm really confused.)
Paolo, you can install a 64 bit OS no problem. OS support is cpu based only. mobo is a platform to use your components together. cpu, ram etc. Your mobo limits you with the amount of ram you can use and type of pcie bandwidth you can get.
for instance, a 32 bit windows operating system (any 32 bit OS for that matter) can not address more than 4 gb of ram. So you can have a 64 bit cpu with a mobo capable of running 32 gb of ram but your OS will only recognize 4 GB's.
and on the other hand, you can have a 64 bit OS which can address 128 GB of ram, but on the same mobo you can install only 32 GB but all of it will be recognized and addressed. So it is like this
32 bit OS(4GB ram support) + 32 GB ram support Mobo = ~4(yeah, even that is not completely available) GB ram available to system
64 bit OS(128 GB ram support) + 32 GB ram support Mobo = 32 GB ram available to system.
