Solved Windows Not Reporting All Memory Tags: Memory Computer Windows XP Last response: October 4, 2010 12:22 AM in Memory Share i_am_jim September 27, 2010 4:39:31 PM I have 4GB of memory in my computer. In the Properties of My Computer in XP it says I have 3GB of memory. msinfo32 and SIW (System Info for Windows) both report 4GB. Why is My Computer > Properties reporting only 3GB More about : windows reporting memory Best solution wiro67 September 27, 2010 6:14:49 PM i assume u use a 32 bit version of XP never mind cause all 32 bit systems wil only see about 3 gb of memory even if you put 6 gb in i would suggest that if you fully want to use the 4 gb or more (in future ) get a 64 bit OS Share i_am_jim September 27, 2010 6:27:18 PM Thank you. The reason I asked was I was about to buy 64bit Win7 and wanted to be sure all 4 gb would be used. m 0 l Can't find your answer ? Ask !
