32 Bit or 64 Bit


Paul Calcagno

Every once in a while I feel the need to ask a question that seems kinda
dumb. So here goes; First I'm running Vista Home Premium, SP2 with 2GB of
RAM, Firefox, Avira, Spyware Doctor, MBAB, and SAS, all WU's current.

Every once in a while I need to know if I have a 32 bit or a 64 bit system
(say for a download). So, I do a run====>msinfo32 and here's what comes up:

OS Name Microsoft® Windows VistaT Home Premium

What I find confusing is that designation for my processor that says AMD
Athlon 64 X2 Dual Core......... What the heck is that 64 doing there? Don't
I have a 32 bit system?
And the system type of X86 is apparently supposed to indicate that it's a 32
bit system. Oh really! All sounds kinda screwy.

Thanks in advance........Paul C.


Systems with 64bit processors can run either the 32bit or a 64 bit OS.
Your are running the 32 bit OS on your 64 bit systems.
A 64 bit OS can only run on a 64 bit system.

Thanks Curious.

Let me see if I have this straight: I have a 32 bit OS running on a
hardware system that could actually accommodate a 64 bit OS. And that's
because my hardware can address data in a 64 bit format.

Correct?...........Paul C.


But of course whether any periferals, eg Printers have 64bit drivers is
another thing
