How do you know it''s time for a memory upgrade? There are several signs indicating it may be time to upgrade your memory. If you see your mouse pointer turn into an hourglass for significant periods of time, if you hear your hard drive working, or if your computer seems to work more slowly than you expect, the reason is probably insufficient memory. When the memory is full, your system transfers data to the hard drive. This is called swapping. Since the hard drive is considerably slower than DRAM, your system seems slower altogether. don''t know the model number of my computer, how can I get the right RAM? Please provide the following information in order to determine what memory you need. You can send it in an email to support@4allmemory.com. How many memory slots do you have? (It will generally be 2, 3 or 4) How many sticks of memory do you have in it now? How much memory is currently installed? (i.e. 16MB, 32MB etc..) What is the length of one stick of memory? (It will generally Please provide all of the numbers off of any stickers on a piece of memory. Look at one of the little black chips on the memory stick and provide all of the numbers off of one chip. (it is generally easier to read the chip numbers if you hold it under a bright light)

RAM (random access memory) is put on your computer using RAM chips placed into special slots. When your computer is turned off, RAM is empty-unlike a hard disk, it can''t store data unless the RAM is powered by electricity. Step 2: RAM''s Power Source When you turn your computer on, electricity flows from the power supply to the motherboard. Because the RAM is directly attached to the motherboard, it gets electricity from the motherboard. When RAM is powered by electricity, it can store data. Step 3: RAM and Hard Disk Relationship The data is now in memory and can be used, manipulated, and altered. The altered data stays in RAM only until you issue a command to save it. When you issue a Save command, the altered data is sent back over the bus to your hard disk, and the data is stored there. When you turn your computer off, the data vanishes out of RAM, but stays permanently on your hard disk.
