XPx32 to Vistax64 upgrade on Pentium 4

kewe65 · 06-02-2008

I recently tried to install Vista Ultimate x64 on a XP Pro x32 machine with a 2.8ghz pentium 4 processor and a D865PERL motherboard. When booting from the DVD to start the process, i get a message saying that the install cannot proceed because the CPU does not support 64-bit. Is the problem truly that the pentium 4 will not work and i need a different processor or am i missing some drivers?

Hi Kewe,

Welcome to Vista Forums.

It depends on what model (sSpec number) your P4 is:

Intel®

You can use this tool from Intel to ID your CPU to compare it to the chart in the link above to see if your P4 is a 64 bit one:

Intel® Processor Identification Utility - Download utility - (Windows* version)

If your CPU is a 64 bit one, then do you have the latest BIOS for your motherboard?

Hope this helps,

The Mother board supports Socket 478, so no luck.

kewe65 · 06-02-2008

to confirm, you are saying that 64-bit is not compatible with socket 478 CPU/MB?

I think some "old" CPU are 64bits compatible with this socket (to be confirmed) but i am quite sure that the bios for the mother board won't work with.

Run the Intel Processor ID software. This will give you the definitive as to whether your processor will support 64-bit:

Intel Download Centre

Look under the 'CPU Technologies' tab to see if it supports Intel 64 Architecture.

*Ahem* - I have an MSI 865PE Neo2 Platinum motherboard with a Socket 478 Prescott 3.2(E) GHz CPU - that is ***not*** 64bit compatible.

If you go to Filter Summary and you enter EMT64 as a filter, you'll notice that *all* Socket 478 CPUs disappear.

There never was (to my knowledge) a Socket 478 P4 CPU made by Intel that supported 64bit architecture.
