RAM stands for Random Access Memory. It is one of the most important components inside a computer. RAM is the working memory of the computer. It serves as a bridge between the hard disk drive ( HDD ) and the processor ( CPU ). When you double-click some program, it is first copied into RAM and then it is manipulated therein. RAM is considered as a volatile type of memory because when the power is gone so are the data inside RAM. That is why you have to save your work frequently when working inside Microsoft Word or any similar program.
When thinking of upgrading your computer’s RAM there are a few things you need to consider first:
1) What kind of motherboard do you have?
There are many kinds of motherboards each with different features and standards. The motherboard is the one who determines what kind of memory and how much memory you can have. One of the core components that have a key role in determining the speed and the size of the memory a motherboard can support is the Front Side Bus ( FSB ). Front Side Bus is the bridge between the CPU and the RAM. Let’s say the that the FSB operates at a speed of 800 MHz. If your RAM modules operate at a speed higher than this they will not work properly or even not work at all. This can happen if you buy a memory module that is too new for a certain kind of motherboard. This is not a problem that happens frequently today because the FSB and the memory modules have various speeds they can accommodate and they adjust their speed according the FSB speed. If you don’t know what kind of speeds your motherboard supports, you can read the motherboard documentation or go online to the motherboard manufacturer’s website. But if you first have to know the brand and the model of your motherboard.You can do this by opening the computer case and watching for that.It is imprinted on the motherboard.
2) Are the RAM slots single, dual or triple channel?
Single-channel means your motherboard can access one RAM module at a time. In this kind of channeling it doesn’t matter the order in which you put the RAM modules into their slots.If the motherboards supports dual-channeling,you have to put the RAM modules in pairs. Every pair should be the same size, the same speed and even the same brand. If you do this, your motherboard can access two RAM modules at the same time. But if you don’t do this, the motherboard will not access two RAM modules at the same time and will operate at the speed of the slowest RAM module. In triple-channeling you have to combine 3 RAM modules. If there are 4 slots and you put a fourth RAM module in addition to the 3 for triple-channeling, the triple-channeling will be broken and they will operate at the slowest speed.
