The last step upon leaving the case should always be to ensure that every cable and power plug is fully seated. If this also does not resolve the problem, try just the new module alone in the system to determine if it is compatible with your system. If the system boots with just the new module, try shutting down and adding the other modules one by one to determine if there may be a chipset incompatibility. What is the difference between ECC and non-ECC (non-parity) memory? If you are unsure of which type you have, just count the number of small black chips on one of your existing memory modules. If the number of chips divides by three evenly, then you need ECC. If the number of chips is does NOT divide evenly by three, you have non-ECC or non-parity memory. If you plan to use your system as a server or a similar mission critical type machine, you may want to take advantage of ECC. If you plan to use your system for regular home, office, or gaming applications, you are better off with non-ECC. Current technology DRAM is very stable and memory errors are rare, so unless you have a need for ECC, you are better served with non-parity SDRAM.

FEATURES RAM comes in the form of a chip, and to increase memory, you simply plug additional chips in to slots on your computer''s main board. The capacity of a RAM chip is measured in megabytes, or millions of bytes. Most systems now come with 48MB of RAM and up. You should have at least 32MB of RAM for running Windows, but with the ever-growing demand for memory, 64 MB or higher is ideal. BUYING TIPS Before buying additional memory for your computer, consult the hardware manual that came with your computer. The manual will tell you what kind of memory is required for your system. It is also important to check the number of RAM slots in your computer, as there is a limited number on the main board for installing memory (anywhere from two to eight). You can only install as many memory modules as you have slots, so plan ahead. If you want to add or upgrade to 128MB of RAM, for instance, get a single 128MB RAM chip, not two 64MB modules. This will save you one RAM slot for future expansion.

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.
