all recalled and replaced by Itanium-II.

Before the feature was eliminated ( Montecito, July 2006) IA-64 processors supported 32-bit x86 in hardware, but slowly.New instruction set, not at all related to x86.It will only work on selective computer system that have the ability to upgrade to 64 bit I have listed for your convenience.

To All buying new computers a helpful advice is you need to have the Windows 64 bit version of any windows for stability and most important the ability to upgrade your memory RAM from 2-4 GB on the 32 bit system in the 64 bit you will be able to upgrade when needed up to 128 GB of RAM that is a major difference between the 32 bit to the 64 bit.
