Vista - Vista x64 Ultimate (OEM version) on Dell D820

Hi
I have a Dell D820 w. 1 GB RAM.
When I try to install Vista and the computer is loading the DVD - I'am told that the pc/cpu is not able to load a 64 bit appl.
It is a Intel T2500 @ 2.0 Ghz. CPU.
I have tryed to change/setup the BIOS (version 7) any posible way.
Have anyone tryed to install Vista x64 on a Dell D820? Please help...

It is not a {{64 bit cpu}} it is only 32 bit and it will not run a 64 bit OS
of any kind
download {cpuz} from the internet it will tell you !!
Good Luck !!

Then why does Dell list Vista x64 drivers for the D820? I never heard of an
Intel Core 2 Duo, Centrino or otherwise, that was not 64-bit. Where did you
get the info that this machine was not 64-bit capable?

Hi,

You will get an error message if you try to install Vista x64 from a 32 bit
desktop. To install any 64 bit version requires you to boot from the DVD.
Make sure that your BIOS is set to boot first from DVD.

Do make sure to back up all of your files and documents first, as 64 bit
must be clean installed. It cannot upgrade your current 32 bit operating
system.

and you'll see that Intel Extended Memory 64 (Intel EM64T) is NOT a feature
of the T2500.

Dell includes 64-bit drivers because a 64-bit capable CPU is optional in the
D820.
Unfortunately, you didn't get one of the higher-end processors.

But that does not mean that it is not a 64bit processor or that it will not
run a 64 bit OS.

According to this:

http://www.intel.com/products/proces...rt/coreduo.htm

variants of the T2500 have VT, which is only availalbe on 64 bit cpus.

Nonsense. The manufacturer is not going to list drivers for x64 just on the
chance a customer might upgrade a cpu. They are listing drivers for the
machine in factory condition. Show me a Core 2 Solo, Duo, or Quad that is
not a 64-bit cpu. Only the Core Solo and Duo are not 64-bit.

programs. No EM64T, no 64-bit.
