usually varies from 2 to 4 to 6 gigabytes.
The RAM that is used for a laptop is not the same as the RAM that you would use in a desktop PC. The RAM that is used for a PC is much too big to be used in a laptop, so a laptop has to use a much smaller RAM card which is called SD-RAM.
The highest amount of RAM that the Apple laptop can support is 2GB. To be able to use the maximum amount, install the memory in each socket of the computer.
RAM (also know Main memory - dynamic ram) which is inside the CPU is used fir holding any data currently in use by the processor.Registers (which are a form of Static RAM) which are in the processor are used forHolding data that is being transferred to or from memory(RAM)Holding the address of the location in memory which the processor is accessing to read data from or write data to.Holds instructionsthat are being executed.
Most likely, the system is set up to use some of its RAM as Video Memory. Many laptops come with graphics chipsets that are built into the motherboard, and that do not have their own video memory. In these cases, the BIOS can be used to configure how much RAM to use as Video Memory. If you have 1 gigabyte of RAM installed, and the BIOS is configured to use 256 megabytes for Video Memory, your computer may report that you have 768 megabytes of memory.
In a desktop you just slide off the cover and put the ram into its slot but in a laptop you will have a screw in the bottom. unscrew it and there should be a lever to release the modular and you can insert in an open spot... if you are going to attempt to do this either see a specialist or understand the consequences.
Answer(Techsupport)Resolution: RAM and virtual memory are two different things. Virtual memory allows you to use a portion of your hard drive as though it were RAM. Your hard drive is up to 100 times slower than RAM, so virtual memory is much slower than RAM. When you upgrade your RAM, you can reduce or eliminate the use of virtual memory. Upgrading RAM makes memory available to complete tasks previously handled by virtual memory.
To run windows XP and Mac OSX they recommend a minimum of 128MB of RAM. However for optimal performance they recommend 256MD for windows XP and 512MB for Mac OSX
no
Yes. Virtual memory is used when there's not enough RAM in your system. It's just hard drive space that the PC sees as RAM. It is much much slower than RAM though. You could run out of memory if you are running enough programs that your use up all your RAM and your virtual memory is used up.
Modern laptops use what are called "SO-DIMM" modules. These are much shorter in length than desktop modules, and are not electrically or physically compatible with desktop memory. Some older laptops did indeed use desktop modules, but these are in the relative minority.
Download the system scanner at crucial.com. This will not only tell you what type of RAM your laptop can use, but also whether your laptop can take any more RAM.
Ram is memory. That means you have 67MB of ram left for you to use out of your 256MB of memory.
