Re: Windows on Xeon 64bit or Pentium?

Tech-Archive recommends: Fix windows errors by optimizing your registry

If server is running only as a File server( no other application) in a Active directory domain does 64 Windows on Xeon will perform twice faster than windows 32bit on the same Xeon CPU?
The domain controler is working on another server, the server with Xeon CPUS is only Fileserver nothing more. What advantages I will get to run Windows 64 bit?
So far I got only problems when testing windows R" 64 bits, hanging, some SCSI card not working (the old adaptec 2940WU)
SATA raid problems.
It is Proliant 4Gp with two Xeon CPUs. It have smart Array with two 72 320 SCSI disks. As a extra disk we added for SATA disks (4 x Seagate 400GB) on Adaptec Sata II RAID 1420SA card.
8 SCSI 76 GB discs connected to Adaptec 2940UW adapter in extenal enclosure.

Any advice?

If you run windows Server 32bit on Xeon 64bit 3.0 Ghz will it be
faster than run it on on Pentium 4 3.0 Ghz.


A Xeon is faster than a normal Pentium 4 of equal clock speed. Nothing to do with 32bit or 64 bits or anything. Xeons have always performed better for server tasks than the equivalent "normal" Pentium processor.


What advantage you can
have running the same 32 bit windows on Xeon 64 bit CPU?


None really. There are some things (such as the NX bit) that are much more likely to be available on a 64 bit processor (regardless of how it is being used), but there is no intrinsic advantage to running a 32bit OS on a 64 bit chip; when you do this your processor is running as a 32 bit processor.
