Hi,
I am trying to figure out whether a Xeon processor is 64 bit capable. I have used the dmidecode software to get the processor ID and other info as below. I don't see "64" appearing anywhere, so I assume it is 32 bit only? Can anyone confirm or deny this?
Thanks very much in advance.
Processor Information
Socket Designation: Microprocessor
Type: Central Processor
Family: Xeon
Manufacturer: Intel

Most ofthe xeons are 64bit so the chances are it is, what is the model of the CPU?

I actually have not been able to figure out the processor model. All the tools I have seen to do that seem to only run on Windows, and this is a Linux box (and I know nothing at all about Windows myself and haven't got a copy anyway). All I know is that the case says Dell Precision 530 on it and it is has dual Xeons of some kind. I think it is from 2003. Not later than early 2004.
Anybody know how to look up the model from the info I do have, or else how to get more info without running Windows?
Thanks in advance.

I was wandering the same thing about this exact same pc. I havn't purchaced it and wanted to know if I could put a 64bit OS on it.

I tried a chat session with an Intel support person, and the answer I got was that the only way to tell (without running a Windows utility which I cannot do) was to remove the heat sink and look for an "SL code" printed on the proc itself. I haven't done this because I don't have any thermal compound or the experience to be sure I won't kill it in the process. But, I have since talked with the person who bought the machine originally and she recalls it as being 32-bit only. I imagine she is correct. I read someplace that a FSB speed as low as that of this system indicates that it wouldn't be 64-bit capable. Not sure whether that is reliable, but it corroborates what the purchaser told me.
I think I will not proceed with this, but for those who wish to:
If you want to look up an SL code, go to http://ark.intel.com
If you can run Windows, you can use the Intel(R) Processor Identification Utility to directly answer this question.
If you do happen to lookup the proc with this ID number, kindly post your results here since it sounds like others may be interested. Thanks.

There is a program "Intel Processor ID utility" which should be able to tell you if your processor is 64 bit or 32 bit. Xeon Processors are supported.

Go to http://www.intel.com/support/processors/sb/CS-015477.htm http://www.intel.com/support/processors/sb/CS-015477.htm and see which version of the bootable utility you should use.
See if that will tell you any additional information.

Looking at the Spec's it looks like an original Netbust Xeon, these didn't support 64bit.
The socket 603 that you have isn't upgradable to any CPU that has x64 support, plus you need the optional risers to support the max of 4GB.
