When it comes to computer parts, referring to RAM it always says: “If you want your computer go faster, buy more RAM!“, but are they really so? What does the RAM and how it can speed up my PC or be the cause of my problems?
The RAMs are a core component of the PC. Without them the motherboard will not allow you to even enter the BIOS. Still, despite being a very important component, are somewhat unknown. Probably too you’re reading doesn’t really know what they do and how to judge the quality of a RAM card. In this guide we’ll talk the characteristics of the RAM. But let’s start from the beginning …
What is a RAM?
EH Yes How to make judging something you don’t even know? You should know that the memories RAM aimed to help the processor in its work, saving inside information about processes and operations that the CPU is or will do. It is a volatile memory and what is written inside will not remain saved for a long time (in fact, just that it takes away the power that loses the information within it). RAM is divided into two components:
– SRAM, which basically is the cache memory. Small size (in megabytes), but great performance and in fact is much more expensive to produce. It is used by the processor to have immediate access to the most common tasks so as to speed up access times to RAM itself. To increase the size and amount of SRAM on a system, it will also increase exponentially the purchase cost;
-SDRAM, which is basically what we mean when we speak of RAM memory. It is the famous cue that install on your PC and that aims, as said earlier, to store information about the operations and instructions that the CPU has to process. There are different types of SDRAM by size (DIMM and SO-DIMM) and performance and structures (divided into four categories: DDR, DDR2, DDR3, DDR4);
That being said, how does the PC to benefit from the presence of RAM? To put it in layman’s terms, the higher the RAM size, the greater the amount of information that the CPU can put in it. So let’s say that this is partly true that RAM affects the speed of your PC, but it is not for all cases.
The RAMs have a working frequency indicating the maximum speed allowed the CPU to use them. So it’s useless to have a RAM very fast if you have a slow CPU because the CPU itself you shall not exploit the characteristics of RAM. And very important to choose well the RAM to install in our PC and with that we pass on to the second point.
How to choose the right RAM?
We said that the RAMs are varied and that then you may risk buy one we don’t need, but how to avoid sbaliare? Meanwhile, we must distinguish between desktops and laptops. Desktops use DIMMS, while laptops use SO-DIMM. So don’t buy a DIMM if you install on a laptop, or a SO-DIMM if your PC is a fixed.
Second thing to do is determine what type of RAM your motherboard can support. As we said there are several categories of RAM and what differs, as well as the speed, it is also the shape of the RAM memory.
In addition to the performance, between the various categories change both the amount of pins or pins that the arrangement of the missing leg. In short, you will be unable to mount a DDR2 RAM on a motherboard that supports DDR4. So does a lot of attention to what kind of RAM you can mount. If you have any questions please read the manual of your motherboard (obtainable on the internet) or a friend for assistance.
The RAMs also have a performance bonus based on the number of installed RAM — the Single Channel (compatible with DDR, DDR2, DDR3, DDR4), the Double Channel (compatible with DDR and DDR2) and Triple Channel (DDR3-compatible).
To take advantage of this increase in performance, mount the right number of RAM according to the following schemetto:
– The Single Channel is activated if you install an odd number of RAM memories (1.3, 5 …);
– The Double Channel will activate if you install an even number of RAM memories (2.4, 6 …);
– The Triple Channel will activate if you install a number of RAM multiple of 3 (3, 6);
The RAM, therefore, improve the performance of my PC?
As we understand it, the answer is relative to your hardware. The RAM definitely increases the performance of the CPU, but only on condition that the CPU and RAM have similar frequencies. Also not all motherboards are suitable for mounting a certain type of RAM. Some motherboards, for example, are compatible with DDR3, but do not support the higher frequencies (like 1600 MHz). Needless to spend so much money on this type of frequencies, and if your motherboard fails to support them (if I mounted a, the motherboard would use the higher frequency supported).
Then you will understand that in order to have a fast and responsive PC you have to balance spending and divide it between RAM and CPU: far better to have a CPU that runs at a rate similar to that of RAM, so you will save a lot of money and not spend much to fix technical errors during the purchase.
Always remember that if your computer is slow, it is not always the fault of the hardware. Many times it is the fault of the software (too bulky for cheap or low end PC) or of the same user who opens too many programs at the same time and puts your PC into constant effort. Resource management is vital to receive maximum benefit from your PC’s performance.
