Im running vista 64 and i have 4 gigs of memory, it shows up in the bios and the windows system page but does not show up in the task manager, ie its not using the other 2gigs is there a buggy update that i need to uninstall becuase it was working at one point and time i just happened to notice this recently.
Edit, Im runing an asus p5n-d an intell core 2 quad 2.4ghz and 2 2gb sticks of muskin
yes this is correct 2045 rather iv ran every memory test i can think of /find iv tryed swaping sticks using one at a time to see if ones defective i switched channels from a to b and vista reconises that i have 4gb installed so does my bios it just wolnt use it all.
you konw i looked and i cant even find one in the bios but it worked before, im thinking about just buying a new mobo i mean i could sware its vista because usualy the os wolnt even show you what your total installed physical memory is if the option isnt turned on.
ok i reset the bios 100% and im still only reading 2045 it really makes no sence to me. im not using any thing in my regular pci slots so thers no reason for it to have it mapped.
type msconfig in the run box. then go to boot.ini or sth like that. then choose advanced options. then uncheck Maxmem option. then restart your pc. then you will see all your memory. Let me know if that works.
