I understand that the Core 2 Duo is a 64-bit processor, while Core Duo is a 32-bit processor. Let me know if my understanding is wrong. My Linux server, with the Core 2 Duo E8400, is currently running Fedora 9 x32. This machine has 4 Gig of RAM and I don’t foresee the need to add any more memory any time soon. Is there any real advantage to changing from x32 to x64? If so, [...]

We are looking at a new environment to run our Oracle Database running on SUSE (potentially migrating to RedHat). Our database is approximately 100GB and performs adequately on our current hardware (x86_64) with approximately 6GB of ram allocated to it. We are growing quickly however and will require more performance shortly. Given the cost of Oracle licenses we would like to maximize the value from each license by choosing the most appropriate CPU to run [...]

I have CentoOS 5.4 x86-64 and every time I do yum install … two versions of the same package are installed: one ending in .i386 and the other ending in .x86_64. Is it nessesary to install .i386 versions given my OS is x86_64? Have I just been wasting space by always installing both .i386 and .x86_64 versions of the same package? From this forum, It seems you need to exclude some specific architectures. Add this [...]

I have an HP LaserJet 4 Plus that I’d like to be able to map (TCP/IP) to my users. I have to give a location for the printer so that the client computer knows where to find the driver. This would be no problem if I add the x86 printer drivers to the Print server properties section of my server and pointed the GPO to the printer installed on my (x64) server. The problem arises [...]

I just want to know if it would be safe to remove all 386 packages from my x86_64 system? Are any of the 386 packages actually used or do they just sit there? The reason i’d like to remove them, is often with updates, there is a clash due to conflicting i386 packages, so removing them would also feel tidier if the system doesn’t need them. thank in advance. Shadi In general, it’s safe – [...]

I have an msdn subscription, but (for the life of me) I cannot find the download for Visual Studio 2010 Professional x64. Is the x64 version included in the X86 DVD? Any help appreciated! Visual Studio 2010 does not have a 64-bit version, only 32-bit. The 32-bit version will work fine on 64-bit Windows. Check more discussion of this question.

Is it possible to mount the NTFS and registry hives from a 64-bit Windows on a 32-bit Windows Preinstallation Environment (32-bit). Does 64-bit change the file format? Also can x86_64 machines boot unmodified 32-bit OSes? There’s no overall data/schema differences between the registries of 32-bit and 64-bit Windows – obviously the actual content will be different but there’s no structural differences no. And yes an x86 64-bit machine can 100% boot a 32-bit OS straight [...]

We are currently in the progress of migrating multiple sites from a x86 win 2008 to a x64 win 2008. We have copied the config dir from and wwwroot’s from the old server to the new server but when we start the server we get a 503 error page and in the event log are 5 warnings and then a error. Warning: A listener channel for protocol ‘http’ in worker process ’2060′ serving application pool [...]
