Installing RAM by yourself
Installation of RAM by oneself must be done in the case in which the fixed motherboard and processor already is located. Approximately here in this:
In the photo above, we see that the installation of RAM has already been made. Also we see the installed motherboard and power supply (indicated by an arrow).
In general, I must say that if you buy a case for a computer , then, often, it is already bundled with the power supply and you do not need to install it. But in any case, the procedure of installing the power supply in the case does not represent anything complicated: put it in the space allocated for it (usually at the top of the system unit )
and securely fix the four bolts on the rear wall of the computer case.
But we will not connect the power yet, but we will install the RAM. The figure below shows how this is done correctly. It is necessary to snap off the plastic clips at the connector itself, gently insert the RAM module into the groove that passes through the entire connector and press it gently perpendicularly downwards until it snaps into place and firmly seated in the slot. In this case, the plastic clips on each side will snap into place, if not - look carefully to the "village" whether the memory bar is the way you want and snap them.
In the figure, the fan CPU fan connector "CPU_FAN" is also circled.
Attention! You could damage your computer! Installing RAM with your own hands is a responsible thing. Therefore, before installing it, it is very important to make sure that you install a suitable memory module in physical memory. For example, only DDR2 memory is installed in the DDR2 connector, only DDR3 form factor memory is in the DDR3 connectors, etc.
If, during the installation of the RAM, it was found that there is no sticker on it (a special label) indicating the type of memory, it is possible to orientate purely visually by the "key". The key is a special "cut", dividing it into several parts in the lower part of its operative memory. Accordingly, each memory slot has a protrusion in the same place. The "key" serves as a kind of protection from the attempt to establish the operative memory in an improper for it physical slot.
Here are two "keys" on the memory of the old standard "SD-RAM":
If you do not want to open the computer, then I recommend using the "CPU-Z" program to determine what type of RAM is installed in it. It will show what type of components your PC consists of. The work of this wonderful utility was discussed in this article.
So, we install all available memory chips in our slots. On modern motherboards they are often marked with different colors (two yellow slots, two - red). This is a mode of dual-channel use of RAM, somewhat increasing its throughput.
To use two-channel (or - three-channel) RAM mode, we need to insert the strips in pairs: two identical modules are installed in connectors of the same color, then the other two - install in connectors of a different color. To obtain maximum effect, the memory chips should be really identical in their operating characteristics of frequency, timings, "CAS" and "RAS" delays. Ideally, they should be purchased in a computer company at one time :)
And the colors of the memory slots on the motherboard of the computer alternate, for example: yellow, red, yellow, red.
We click all clamps, check that all memory modules "sit" in the connectors exactly (memory chips should be on the same height line, without raised edges and "protruding" latches).
This is how the RAM is installed in such a simple way. As you can see, everything is simple :)
