As an experiment I fitted 4 GB worth of memory chips msinfo32 says Total Physical Memory 4,096.00 MB Available Physical Memory 2.44 GB Total Virtual Memory 2.00 GB Available Virtual Memory 1.96 GB Page File Space 5.86 GB System properties says Pentium 4 CPU 3GHz, 3GB of RAM. Paging file on C: is 16Mb 16Mb Fixed and on D: System managed I have added /PAE to boot.ini file Motherboard is Gigabyte GA-8I915-MF Any suggestions why it doesn't see all the memory?
gudgulf I have set my page file to 2mb 2mb and none on D:. msinfo32 still says same as above except Page File Space 5.84 GB I have looked around the web and it seems as that opinions vary, it may be that the RAM is being used but winxp is not admitting it. Why do mobos allow up to 4MB RAM, maybe that was my mistake, I should not have RTFM for my mobo. Vista perhaps? Will close thread unless anyone comes up with other ideas, after all, this is not really life-threatening
