why does my pc show only 248 of 256mb of RAM?

Answer 1

I don't know why but it is normal to always show a little bit less.

Answer 2

When you buy RAM the vendor counts each of the bits in labelling it. That higher number is what he advertises for sale.

When you use the RAM in your computer the computer says that it takes 1024 bits to make one kilobyte and a thousand of those to make 1 mb. When it does its own configuration it thinks of the same memory as 248mb.

same bits - different way of thinking about them.

Answer 3

You may have on board video ram, where there is not a dedicated graphics card.

Thus 8mb is used for video operations (very low amount) or in conjunction with sound or cache (to make programs run faster).

Answer 4

The on-board graphics uses 8 MB of system RAM for its own video RAM.

I have a laptop whose on-board graphics uses 64 MB of system RAM for its own video RAM.

I'm not a fan of such arrangements and I would rather have systems with their own graphics cards with their own memory.

Answer 5

256mb ram is your installed amount not your usable amount like on a hard drive i have 100gb hard drive on my laptop but i can only use about 92gb i have 2048mb ram (2gb) but i can only use about 2020mb

Answer 6

8 MG caches to the Motherboard for its operations.

Answer 7

your operating system uses some of it, the rest is available to use for the rest of your every day tasks

Answer 8

the rest is taken by Windows

Answer 9

you may have an intergrated (on-board) video card, it will use some of your RAM.
