6gigs of ram and only 3.99gigs is being used... help?

this is my specs for my comp...
Processor: Intel(R) Core(TM) i5 CPU 750@ 2.67 GHz 2.67 GHz
Installed Memory (RAM) 6.00 GB (3.99 GB usable)
System Type: 64-bit OS

can anyone please help me on how i get all my ram to be used? i was reading up on it and i saw that there was something in the BIOS that i might have to change... I looked and couldn't find anything about RAM. im not that good at BIOS so if someone could explain it to me like im a baby, that would be great.

I find it suspicous that 4 gb is the amount the 32 bit version uses. Are you sure you installed 64 bit?

positive. i got my specs from what my comp had in the properties in My Computer

Something in the Bios settings is the most likely suspect. Win 7 uses processors and memory in a whole new way. I had to flash my bios so it could use the new milti-thread features.

Maybe take out a memory stick and see how the report changes.

Good luck
