In my system imformation it tells me, installed physical memory 1gb, total physical memory 767mb, available physical memory 253mb. Why is my total physical memory not 1gb. I am running vista 32bit. Many thanks for your time.

maybe the motherboard does not support 2 GB of ram you could try 1gb+500mp in the other slot
to check how much ram your computer can/has
click start all programs accessories system tools system imformation you will see all imformation of your computer right including the ram
hope this helps

This is because your computer is sharing the physical memory with the graphics memory so it will actually subtract the amount of the shared memory from the physical memory in the computer giving you the 780 that you see because the computer reserves a portion of that to use for your graphics.

I HAVE DELL COMPUTER, INSTALLED WINDOWS XP BUT NO SOUND PLS SOLVE IT

Hey,

it should show in the bios as 2048.

looking at the details of the motherboard
Memory Type DDR SDRAM Number of Memory Slots 2 x DIMMs Supported RAM speeds 400 MHz

Got the right speed ram etc?



Thanks,
Ekse

It sounds like something isnt working right, what operating system are you using, Vista? I would take out the original 512 and see what it says after, often ram isnt compatible if it is too different in size and speeds. Also, if your motherboard supports dual channel ram and you have the extra 512 chip it wont run in dual channel mode, you would run better with just the 2 chips then the added 512 chip.

goto httop://www.crucial.com and run the automatic detection service, it will tell you exactly what ram you can get and what ram is in there and they have about the best prices as well.

Physical memory is ur addon hardware memmory available memmory means  256 - currently usage virtual memmory = free space in ur c drive page file space is related to virtual memmory cipher strength is encryption level of your internet explorer

goto http://www.crucial.com/ and run their memory checker. it will tell you what can be put in your system. They are very competitively priced.

Most likely, it is a limitation of your motherboard. Not all motherboards or computers can physically read all types of memory or they may have memory limitations. For instance, I was working on an older Gateway this week. It had 2 memory slots but the maximum amount of memory the computer would recognize is 512 MB. Therefore, if I had put to 1 GB sticks in, provided the computer could use it, the maximum the computer would be able to see or use is 512 MB. In this instance, that is most likely the scenario. The best thing to do is to go to www.crucial.com and run the system scanner. It will tell you how many slots you have, what the maximum per slot capacity and the total capacity of your computer is.

Thanks and please take a moment to rate as fixya.

available physical memmory is what all your programs on your comp is using like windows virus software drivers im thinking you probably have spyware or bugs in your comp that could be bringing memmory down

total physical memmory is what you just put in
