Hi i am preparing a new PC (Intel Core 2 Duo 6700) for FS X with 4 GB of speedy Corsair memory and an ASUS P5N32-SLI SE deluxe motherboard.Installing the Windows XP-Home (SP2)I could not install it with 4 GB memory (4x 1GB); it did not boot after installation.Taking off 2 GB it works.Does Windows XP-Home SP2 NOT work with 4 GB of memory?ThanksPeter

http://www.anandtech.com/mb/showdoc.aspx?i=2797&p=6Mobo supports 16mb of unbuffered memory, but XP Home becomes increasingly problematic with anything more than 3-gig, and a practical limit of most uses of 3.2gig, with greater problems the closer you get to that limit, paricularly if you have a number of PCI devices and Nvidia graphics card (their 32-bit drivers really don't like encountering systems with more than about 2-gig of memory).So what you have there is a system waiting for Vista. But then Vista has its own problems! ;)Allcott

AllcottThanks.1. So I will use my new system under Windows-XP Home with 2 GB memoryand then end of january 07 upgrade to Windows Vista Home Premium; that will support my additional 2 GB (total of 4 GB) memory: RIGHT?2.**********So what you have there is a system waiting for Vista. But then Vista has its own problems! **********What du you mean with this; what problems have I to expect?Peter

Hi Peter, AFAIK, XP-Home is not a good one to upgrade from. Best would be to buy MCE and upward if you don't want to get stranded with limited upgrade options or face significantly higher prices once you do. Hope this adds to thoughts despite not being able to help with RAM limits. Kind regards Jaap

MCE is the "media center edition" of XP, which isn't supposed to be sold directly to consumers, only as a pre-load, though I guess it is possible to get your hands on it. Current selling computers with MCE get a Vista upgrade at (I think) reduced cost. I think Vista Home Premium is intended as an upgrade to the MCE. There will be off the shelf Vista upgrade packages for XP home/pro (32 bit), but that will cost more. To upgrade to Vista 64 bit you have to have XP 64 bit.scott s..

Hi Scott, thanks for the explinations. Pls note though, there is quite a difference between XP Home and Professional, pro will offer more upgrade options. Kind regards Jaap AFAIK = As Far As I Know

Everything I'm reading right now is suggestig to me that the VERSION of Vista is going to be a significant factor simply because of the increase in overheads as the sophistication increases, offset by the need to have a version that will actually fulfill the function of a gaming computer.http://www.extremetech.com/article2/0,1697,2068721,00.aspAllcott
