Still confused about the different types of RAM?

It is very easy to become confused with the different types of RAM that will or will not run on the different types of motherboards that support Intel or AMD processors.

Start by remembering that motherboards that support Intel processors never support AMD processors, and you are half way towards clearing up the confusion.

The motherboard must support a given processor if you are to use it. It is then just an simple matter of consulting the motherboard's manual to find out the types of RAM and the processors that it supports.

You can download the manuals from the websites of most of the major motherboard manufacturers. As long as you only install items on a motherboard certified by its manual to run on or with it, you cannot go very far wrong.

Most systems that have motherboards that use SIMM memory modules require you to use matching pairs of modules to fill a bank of slots on your motherboard. If you fail to match them correctly, your system will probably not function properly.

For example, if you want to install 64MB of EDO RAM that comes in the outdated SIMM module form, you may have to install two matching 32MB modules instead of going with just one 64MB module, or one 32MB module plus two 16MB modules. Therefore, always check your system and motherboard manuals before you place an order.

Note that you do not need to install DIMM (SDRAM or DDR RAM) modules,in pairs. Modern motherboards are also often much more forgiving about which DIMM modules that can be fitted - they do not all have to be of the same capacity. - A 64MB module can be installed with 128MB and 256MB modules.

Remember to never skimp on quality when it comes to buying RAM.

Even when buying a new PC always obtain a system specification and check what make of RAM is installed.

Only grade-A memory will do, and it is only manufactured by the major manufacturers of RAM.

RAM is probably the most critical system component. Every bit of data passes through it to get to the processor, so it has to be 100% functional 100% of the time if data corruption is not to take place.

It is a fact that many program crashes can be attributed to cheap, error-prone or defective RAM. Therefore, if the system has generic, low-cost RAM, insist that grade A RAM from one of the major manufacturers is installed.

If the vendor's advertisement, or system specification does not name the manufacturer, then it is usually generic RAM that is on offer, much of which is not likely to be grade A RAM.
