Today''s software has become more rapacious than ever—not just wanting faster processors, but faster graphics and more RAM. Layer these software programs on top of itself a memory-hungry operating system, and it becomes clear that more memory is better—up to a point. The good news is that memory is cheaper than ever, though the precipitous plummet in prices seems to have leveled off a bit lately. But the memory landscape is much more confusing than even a couple of years ago. The acronyms have evolved into a veritable alphabet soup of memory types: EDO, BEDO, SDRAM, FP, RAMBUS. Each new motherboard chipset that finds its way into your computer seems to want a different type of memory. Well, we''re here to help you sort through the memory types and walk you through the process of installation. This is a tough question. However, there are a couple of rules of thumb. First, know thy motherboard. You must be aware of what chipset you have in your system. It turns out that adding too much memory can actually slow down your computer. The reason for this is the L2 cache. Cache Level 1 and Level 2

What does the CL stand for on memory chips? CL stands for CAS Latency. When a module is labeled CL2 it means there are only two clock cycles before the module can send the first block of data. CL3 means there are three cycles before the first block of data is sent. Cl2 is considered to be a small percentage faster than CL3 modules. PC100 and PC133 modules are manufactured as both CL2 and CL3. You will need to check with your system''s requirements to see which option is compatible with your system. Does it matter which slots I plug my new module in? In general, you will get the best performance if you put the largest module (in megabytes) in the lowest-numbered slot. For example, if your computer comes with 32MB of removable memory and you want to add 128MB, it would be best to put the 128MB module into slot 0 and the 32MB module into slot 1. My system will not boot after installing your memory? Are you getting an error message on the monitor? If it states a Non-System Disk error occurred, check to make sure that you do not have a non-bootable disk in the floppy drive, or even the CD-ROM drive if your system can boot to the CD drive.

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.
