I bought DELL Precision 490 with 2 Dual Core Xeons and Windows XP
64 bit. Some of my programs do not work on this system. I replaced
OS with XP 32 bit.
I see in device manager 4 processors. Does it mean that at least
with some programs all of them will be used?
I've read somewhere that XP supports up to 2 processors. Is it about
Just because the OS can utilize the dual processors, multiple cores means
little to nothing for the applications themselves.
Personally - given what you have - I would have either seen if the
applications that wouldn't run in 64bit had updates to allow them to or I
would have ran a virtual WIndows XP Professional session for those that
won't run in 64-bit.
Windows XP Home supports a single CPU - but as many cores as you can stuff
in that single processor (so Windows XP on a quad-core system will show the
'4 CPUs' in Task Manager - even though that just actually represents the 4
cores of the single processor.) Windows XP Professional supports dual
CPUs - but as many cores as you can stuff in those processors (so Windows XP
Professional on a dual - quad-core system will show the '8 CPUs' in Task
Manager - even though that just actually represents the 4 cores of each of
the processors.)
Applications will utilize them - but not in the optimized way that an
application written to properly utilize them would.
