Xeon memory addressing greater then 4gb

Greetings,

I've acquried a Gateway 955 1u server with dual Xeon 3.06 / 533 socket 604 processors.
The manual states the maximum memory for the server is 12gb.
When I run the Intel CPU ID utility it shows the cpu's as "NOT" having Intel 64bit Architecture.

If the cpu is not 64 bit how can it address 12gb??

Thanks in advance,

  1. PAE - (36 bit mode)
  2. if any cpu is a dual core, quad core or maybe single but with hyper threading it should be 64bit. you say acquired, as in just bought new or its an old system. i thought all xeons were 64bit

    Only recent Xeons are 64bit...

    But ALL Xeons support PAE (Google it)

    thats why i asked him if it was a new system, (he said aquired, could be old) but if he just baught it then it should be 64bit. for PAE ya, so the 12GB is supported. but a 54bit OS is needed
