skelley Posted August 27, 2007 Share Posted August 27, 2007 I have a dual 2.66ghz core duo mac running windows xp. I have 4 gigs of ram but only 2 gigs are recognized in windows. Is there something about windows that only recognizes 2 gigs or is it that I am running it through bootcamp? 0 Quote Link to comment Share on other sites More sharing options...
Battlefront.com Posted August 27, 2007 Share Posted August 27, 2007 It shouldn't have anything to do with Bootcamp as far as I know. And XP should be able to access 4GIG of RAM, so don't know what the problem might be if the Mac side of things is recognizing them. Steve P.S. I moved this to the Tech Support Forum since that's where it should be. 0 Quote Link to comment Share on other sites More sharing options...
skelley Posted August 27, 2007 Author Share Posted August 27, 2007 when running Mac OS it tells me I have 4 gigs of ram. when in windows and go to system properties it says 1.98 gigs. Do you think it is maybe that the ram is in two bays now? But even if it is that it should at least see 3 gigs because in the top bay I have 3 and the lower 1. Thanks for any feedback 0 Quote Link to comment Share on other sites More sharing options...
cmezriczky Posted August 27, 2007 Share Posted August 27, 2007 I don´t have a dual core mac, but as far as I have understood the CTO variants it should have 2 Bays with 2 GIG each to come with 4 GIG RAM. Maybe thats why... 0 Quote Link to comment Share on other sites More sharing options...
Steiner14 Posted August 27, 2007 Share Posted August 27, 2007 From what i know, you need XP 64Bit to adress all 4 GB of RAM. 0 Quote Link to comment Share on other sites More sharing options...
skelley Posted August 28, 2007 Author Share Posted August 28, 2007 that sucks...why would you write an OS that can only recognize 2 gigs o ram? 0 Quote Link to comment Share on other sites More sharing options...
Steiner14 Posted August 28, 2007 Share Posted August 28, 2007 Because a bigger adress room needs longer adresses and longer andresses need more computation if the computers can't handle the long adresses natively. 0 Quote Link to comment Share on other sites More sharing options...

Pzman Posted August 28, 2007 Share Posted August 28, 2007 Originally posted by skelley: that sucks...why would you write an OS that can only recognize 2 gigs o ram? A Windows XP 32bit can only read 2GB, while 64bit can read a lot more, problem is 64bit version is not support by Bootcamp, IIRC. Meaning, Apple's Windows drivers are not 64bit, so you'd have to find drivers for hardware, which would be hard, if not impossible to do. from Apple.com A bona fide full version of Microsoft Windows: XP Home or Professional with Service Pack 2, Windows Vista Home Basic, Home Premium, Business, or Ultimate. (No upgrade or multi-disc versions). 0 Quote Link to comment Share on other sites More sharing options...
