Is there something wrong if i had 6gig total memory installed but im only getting 3.99gig in the physical memory and the reason for asking this is that. I just got my GTX480 RMA and when i installed it i suddenly have freezing issues which never happened before. when trying to install a fresh copy of vista home 64 bit it just freezes. When i got through the installation problem my computer just randomly freezes. plz need help asap sorry no time for correcting grammars XD
Yes the total installed memory should match the total physical RAM - however depending on where you are reading these figure from and what operating system you are running the figure can be misleading.
Firstly you need a 64 bit OS to see more than 3.2 gig or RAM - so if you are rnning XP / Vista / 7 in 32 bit guise then you wont see the whole figure
Next... Vista was a pain for running with more than 2 gig of RAM - depending on how old your installation disc is. I used to have Vista 64 with 2 gig then upgraded 6 months later - somewhere in between a patch was released for Vista 64 to recognise 4 gig. So if you problems installing a fresh copy then remove 2 gig of ram and install - then run all the updates before adding the extra 2 gig.
