How do we find out if an Intel Xeon processor is a 32-bit (IA32,x86) or 64-bit (EM64T,x86_64)?

Hi,

We have a lot ofDell andHP servers in our lab that have xeon processors.

How do we find out if an Intel Xeon processor is a 32-bit (IA32, x86) or 64-bit (EM64T, x86_64)?

Please suggest,

Thanks & Regards.

Hi,

If you've made no modifications to the systems, your best bet would be to visit the computer manufacturers' Web sites to consult the spec sheets for your models.

Otherwise, please see thisthread to find links to processor identification tools both for end-users and for software developers.

if you're running Linux on the systems, you can use check for the 'lm' (long mode) flag in the CPU information to identify EM64T enabled processors.

cat /proc/cpuinfo | grep flags | grep lm

I'm sure there is an equivalent in Windows.

Hello gshekar,

Our experts sent me additional resources andinformation which I am posting for you here regarding your question:

http://download.intel.com/design/Xeon/applnots/24161831.pdf- Please refer to page 35 in this Acrobat file, specifically Table 3-14. "Extended Feature Flag Values Reported in the EDX Register"

If you dont have Linux on that system, still you can do same by booting with knoppix cdrom. The knoppix cdrom can be downloaded from here: http://www.knoppix.org/

If these are production parts you can use the Intel Processor Spec finder and check against the SSPEC on the processor: http://processorfinder.intel.com/List.aspx?ProcFam=528&sSpec=&OrdCode

I hope this helps.
