Identifying a system is a IA64 or X64

[Former Member]

Hi Friends,

Can anyone help me how to determine whether a windows server is IA64 64 bit or X64 64bit.

I can determine whethere it is a 64 bit or 32 bit through System information. But not able to find whether the system is IA64 or X64. Please help.

Thanks,

kris.

dxdiag is used to check drivers, it's not a tool to diagnose bitness.

"System - Status" in an ABAP instance will also tell in the left bottom corner the architecture as well as OS06 or OS07N.

Hi Uday ,

Just a small hint , As per my knowledge don't get confused with AMD64T & EMT64T as both are same processor architectures.

Only IA64 differs.

Try

Start - execute - winmsd.exe

This will show you under the processors either "ia64" - which is Itanium-2 or Intel/AMD 64 which is x64.

There is only one major vendor actually producing IA64 servers (aside from SIG/Cray with their ALTIX machines) - HP. The machines are "Integrity".

So if you have a DELL or IBM server, it's certainly an x64 machine.

Hi Markus,

Don't forget Unisys.

We use Unisys Aries 410 or 420 servers with ia64 processors.

These are windows servers without a graphic card.

Salut Olivier!

I forgot them - yes - you're right.

According to their website they don't use Itanium any more, all their current server models are Xeon or AMD based. This was also communicated in the press -they don't built any more servers with "Itanic":

So the only vendor staying is just SGI/Cray.... (aside from HP)
