bookie32 Posted January 11, 2011 Share Posted January 11, 2011 (edited) Hi folks!Just upgraded my media center and have installed 6GB ram? I have 2+1+2+1 The memory is Corsair PC6400 800MHZ xms2.The bios sees everything. Even Windows says I have 6GB installed, but I get told that I can only utilise 3.5?OK! What am I missing here? I thought that 64bit could use everything...bookie32 Edited January 30, 2011 by bookie32 Link to comment Share on other sites More sharing options...

bookie32 Posted January 12, 2011 Author Share Posted January 12, 2011 Hi Mr SnrubYour info worked a treat....THANKS for that!MagicAndre1981Thanks for another tool I can use.....Have attached a pic..Thanks a lot!bookie32 Link to comment Share on other sites More sharing options...
MagicAndre1981 Posted January 12, 2011 Share Posted January 12, 2011 (edited) Have you enabled the option, like suggested by Mr Snrub?the output looks strange. Have you used the 64Bit version of the tool? Also check under msconfig.exe->boot advanced settings that you don't limit the RAM.

cluberti Posted January 15, 2011 Share Posted January 15, 2011 Just to confirm, if you run resmon.exe and click on the memory tab, does it say the "missing" ram is Hardware Reserved? Link to comment Share on other sites More sharing options...
