More than likely you have an "onboard" video or sound device which is taking part of the memory.
Only five.
no, not at all it only takes PC100 RAM at a maximum of 512MB or 1GB I think only 512MB. I have a Latitude CPx J750GT PIII 750mhz that won't boot with PC133 from a C610 which is another C series laptop.
Where have you seen a USB graphics card? There are none AFAIK. Soon with USB 3.0 there will be some ways to do this, and I think they will ALL have more than 512mb because only very old cards have that much.
Read the system requirements for the game. The critical factor is not the computer speed it is the graphics card. If you have a separate one with 128 mb memory or higher, it should play but only at low resolution. Nvidia 7600 or higher, ATI 1300? or higher.
Only half of the Human eye is showing.
No special adavantage in using 256 with 512.It will give the performance of only 512.use the same size
Through the magic of Virtual Memory, though it might page to disk more often than you want.
In theory it will run faster with the 512Mb stick, as the computer only needs to send and receive date from one source, as opposed to two, which takes more system resources (regardless of the memory size of the two sticks).
The Motorolo V3I was introduced in November of 2005. It was on a 2G network and had a small microcard slot that would hold up to 512Mb. The weight of the phone is only 100g.
On the midnight showing, around $25 million - that was only for the midnight showing, though

You can use either a 32bit or 64bit operating system (OS) for 4GB of RAM. 4GB of memory is the limit a 32bit OS can handle, this includes any memory that your graphics card has, so your computer may recognise only 3.5GB of RAM if you have a 512MB GPU. You will need a 64bit os that will use all of the ram.
