i have a problem, In my bios it would show 4gb of ram installed, but only 3.2gb in my comp specs (i have vista ultimate 64 bit). i understand why it takes up that 1 gb because of my video card. I installed another 4 gb of ram into my computer. a total of 8gb of ram (i know its overkill but its for the future) my computer now shows 8gb installed in my bios but comp specs show 3.2gb still. i think i need to enable memory remapping. i dont think my bios supports that though. i have an Inspiron 530 from DELL. its quad core 2.4ghz. i dont know what my problem is exactly. I just dont understand why it would still show 3.2gb when i have 8gb in it. would anyone know what i can do to fix this?
