You can think of RAM as an incredibly fast hard drive that stores information temporarily instead of permanently. When you start a program it is loaded from the hard drive into RAM. When a program is running in RAM it can run hundreds to thousands of times faster than it can if run directly from the hard drive. The problem is that the capacity of a standard hard drive is many times the size of a computer''s RAM size, meaning it is possible to load so many programs that the RAM can no longer hold them. When that happens, your computer''s virtual memory kicks in, and that''s bad. Virtual memory is simply your hard drive trying to act like a RAM chip. Since the hard drive is so much slower than real memory, programs stutter and sometimes crash when the hard drive has to do a job it was never designed for. There are only two solutions to this problem: close some programs until virtual memory is no longer needed, or add more physical memory. If you can afford it (and current memory prices are low enough that practically anyone should be able to), the latter solution is always preferable.

What is PC-100 memory? Simply put, PC100 is a faster main memory bus, transferring data at 100MHz. Up to now, the fastest common PC bus speed has been 66MHz, so PC100 represents about a 50% theoretical improvement in speed. Tests have shown a typical speed increase of over 20%. Do I need to remove the stickers that are on the chips of my new DIMM? DO NOT remove any stickers from the modules. Removing these stickers will void the warranty. The main sticker is the bar code sticker which has the serial number under the bar code. This bar code number gives us all of the information about the modules that we require for warranty replacement and information, as well as allowing us to determine which module you have and what its characteristics are. These stickers will not have any affect on performance nor will they be affected by the heat inside the system. What is VRAM? VRAM is an acronym for Video Random Access Memory. Video memory is DRAM (Dynamic Random Access Memory) with an on-board serial register/serial access memory. It is designed for video applications.
