Guest Daniel Jameson Posted June 27, 2008 Posted June 27, 2008 Hi, Does anyone know definitively whether Windows XP will run on dual quad core Xeon hardware and use all 8 cores? -- Daniel Jameson ·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.·.· You don't have to agree with an artist's opinion to appreciate the art with which he expresses it.

I am running 2 dual-core Xeons on an ASUS PC-DL and Task Manager shows 4 CPU Usage graphs. XP "thinks" it has 4 logical processors. As far as "using" all your cores, the OS will, but very few applications know how to do this (some imaging software, some video transcoding software) and will continue to poke along using only 1 core. But multi-cores will allow you to run lots of apps simultaneously at full speed and will offload OS chores to other cores. > > Carl
Guest Daniel Jameson Posted June 29, 2008 Posted June 29, 2008 Re: XP on Dual Quad Core Xeon Hi, Yeah, video transcoding is exactly what we want to do with this thing, and we are going to double check with the app publisher to make sure it will take advantage of 8 cores. Thank you. Dan.
