How to verify X64 processor compatibility?
We have Dell Precision 490 and T5400 we want to upgrade to X64 OS. I tried to catch with WMI the x64 architecture support but it seams that win32_processor.Architecture is not reliable. The CPU type collected by WMI gives "Intel(R) Xeon(R) CPU 5160 @ 3.00GHz" and "Intel(R) Xeon(TM) CPU 3.73GHz" for P490 stations and "Intel Pentium III Xeon processor" for T5400 stations. Can you tell me if these processors support nativeley the X64 archictecture or can you give me a mean to verify this support?

Hi
Go here www.cpuid.com and download cpuz , run it from the desktop then look at the line that says instructions if you see EM64T the cpu will be able to run a 64 bit OS like XP PRO 64 bit ,Vista 64 Win 7 64 .
Good Luck

Thank you for your help. I ran the test on some desktops and CPUZ returns EM64T to YES. I wonder all the same if there is a mean to capture this support status by scripting WMI or registry. The Architecture item of Win32_Processor class (item DataWidth too) or ProcessorNameString of "HKLM\hardware\description\system\centralprocessor\0" key or Processor_Identifier of "HKLM\system\currentControlSet\Control\Session Manager\Environment" key are always related to OS currently installed. We are running XP SP2 and i'm being to be convinced that under this level of OS there is no solution.

Hi
I have read your post several times but i am not sure about what you are asking with the info you have used i do know if cpuz says EM64T you can run a 64 bit OS .thats all i can help you with maybe someone will come along to help you with the other info !!
Good Luck

If i have to verify EM64T support for some PCs, CPUZ is the solution but if i have to do it on several hundred of PCs then only a script is the solution. And as i said in my answer, the solutions found on the net don't apply with XP SP2. Normally, Architecture=9 or substring 64 in Processor_Identifier or ProcessorNameString means that the processor has the 64 bits support built in. But this is not true under XP SP2. All these values are OS currently installed related. As we are in X32, they exhibit X32 value.
