DIY installation is to choose the computer hardware by ourselves and all the hardware can be flexibly matched together under the condition of ensuring compatibility. DIY hardware includes the processor, graphics card, motherboard, memory ram hard disk chassis, power supply and so on. When we searched the memory on the shopping website, we found that the memory has many brands, various capacities and complicated models. RAMAIGO is mainly talking about the knowledge of DIY installed memory selection, teaching you how to choose the right memory.

1. Memory brand

Regarding the brand of memory sticks, Kingston is a popular brand and has the highest market share. It is also the preferred brand for most users. If you pay more attention to the value of price then you can give priority to RAMAIGO.

2. Memory capacity 

Now the memory capacity on the market is generally 4G, 8G, 16G single. If you want more memory, they can be built by purchasing multiple memory of the same model. The common motherboards are two and four memory slots, some high-end motherboards will support more memory slots. Now mainstream motherboards can support up to 64G of memory, while some high-end motherboards can even support 128G of large memory, while 64-bit processors support up to 128G. 

Now for ordinary office computers, 4G memory is enough and the game computer recommends 8G or 16G.For some planners or users of computing programs, we can consider appropriate upgrades according to their own needs.

3. Memory type

The memory type mentioned here refers to the "DDR2", "DDR3", "DDR4" etc. Now the new mainstream platform is DDR4. For some old computer upgrades, it may be DDR3 or even DDR2 memory.

When we choose the memory, we can refer to the memory of the motherboard or the processor support (you can check the "memory specification" parameter of the motherboard). In short, starting with the intel 100 series motherboards, DDR4 memory has been supported, and the new generation of AMD Ryzen full range of processors has begun to fully support DDR4 ram.

4. Memory frequency

The frequency of memory, such as DDR4 memory from 2133MHz to 3600MHz, many high-end memory even has a higher memory frequency then the memory frequency will affect the performance of the computer?

Simply put, the capacity of the memory is equivalent to the diameter of the water pipe and the frequency of the memory is equivalent to the valve of the water pipe. The larger the valve is opened with the faster the water flow. Therefore, in the case of memory of the same algebra and capacity, the higher the memory frequency, the higher the performance, but the higher the frequency, the higher the memory price

5. Dual channel memory

The dual channel memory technology is a means to further improve the performance of the computer. Simply put, the two memories are improved from serial to parallel which can get more memory bandwidth and thus increase the speed of the memory. In addition, dual channel memory is more conducive to nuclear computer, especially APU platform, dual channel memory has better optimization

The dual channel memory requires motherboard support and now all motherboards support dual channel. The dual channel of the memory does not need to be set in the BIOS. Generally, the motherboard with two memory slots can also be configured with two channels of memory to form dual channel memory, and the motherboards of the four memory slots need to be "spaced", for example. Respectively 1, 2, 3, 4 memory slots, we can insert the memory into the 1, 3 memory slots or 2, 4 memory slots to form a dual channel, no complicated settings, the way is very simple.
In addition some high-end platforms such as the Intel X299 and AMD's X399 motherboards, can support up to four channels. The so-called dual and quad channels are mainly determined by motherboard support.

6. Memory overclocking and timing

Regarding the overclocking and timing of memory for ordinary users, the two need not be particularly concerned and many installations are still simple to introduce.
The so-called overclocking that it is not difficult to understand, I believe that the vast majority of users know that it is to increase the memory frequency by increasing the voltage and adjusting the timing so that the memory performance is stronger, but not any memory can be overclocked, the key needs to see Memory physique.

The timing of the memory that the vast majority of users certainly do not know. the memory timing is the delay time of the memory, we can use CPU-Z in the SPD to view the memory timing generally similar to "16-16 The four sets of data of -16-39" are represented, wherein the first set of data represents the CL value and is also the most critical value in the time series. In the vast majority of cases, under the same frequency of memory, the lower the timing, the higher the performance, but it cannot be generalized.

7. The appearance of the memory

Along with the development of the side-through chassis, many installed users will give priority to the vest memory and light bar when selecting the memory, especially the light bar is relatively hot now, which can make the interior of the main box more dazzling, more suitable for light pollution.

In addition, the appearance of the memory algebra is different. Although the memory looks like the same at a glance, it will change if you look closely. For example, the appearance of "DDR4" and "DDR3" memory respectively, compared with the DDR4 memory and DDR3 ram is more centered, and the golden finger of DDR4 memory is curved, and the golden finger of DDR3 memory is straight-line smooth planning, which means that different algebraic memories cannot be compatible and used.

Now everyone needs computer whether playing PC games, working, designing or learning. So assembling a computer is a good choice because can be customized and affordable. In the purchase of hardware is easy to produce misunderstanding of hardware, Now we share with you the DIY installation and purchase of computer hardware such as motherboard, memory ram, CPU, Graphics card and so on to avoid the guide for the majority of users to bring DIY machine selection hardware misunderstanding.

1. AMD lags behind 

Many people think that AMD obviously lags behind Intel in terms of architecture, process and power consumption. However after AMD released the Ryzen series processors, many AMD's processors have the same performance with Intel's same-level processors. Especially the 14 nanometre process and heat generation are better than Intel and with not so big calorific value. If you take the cost-effective route, the boxed CPU is also equipped with a better CPU cooler than Intel. In addition, the internal soldering process of the processor is used and the temperature control is better. The most important thing is that the price is much cheaper.

2. Intel Core i5 must be better than Core i3

Many people think that i5 is better than i3. For example, the latest eight-generation i5 processor is recommended according to the budget, but some users will say that was equipped i5 a few years ago and now at least upgrade i7. In fact, every generation of Intel has i3, i5, i7 and each generation has performance improvement. For example, the eight-generation i3-8100 is basically the same as the seven-generation i5-7400. 

3 Independent graphics cards have higher performance than integrated graphics

If your computer is equipped with GT610, GT710 or other old graphics cards, its performance is not as good as the current Intel Core and AMD Acer APU built-in core. The cheaper old discrete graphics card basically does not need to be considered, unless there is no built-in graphics card. Ryzen is just playing the role of a bright machine.

4. The big motherboard is stable compared to the small board.

The size of the motherboard specification has nothing to do with the stability. The materials used for all big or small boards are the same. The main difference is the expansibility. The expansibility of big motherboard is better than small board, such as multiple PCI-E graphics card slots, 2-3 more PCI slots etc. However there is no need for dual graphics cards, TV cards, acquisition cards, high-end sound cards and other expansion requirements, small boards can be suitable. In addition small boards are cheaper than large ones.

5. High-end motherboards with better perform than low-end motherboards
In the case of the same chipset on the motherboard, whether high-end motherboard or low-end motherboard, the main difference is the work materials, there may be some popular RGB lighting effects, wireless network cards, etc. and the impact on computer performance is minimal, almost negligible.

6. Water cooling is better than air-cooled CPU cooler
Water cooling is definitely better than air cooling in theory, especially the split-type water cooling in a fever configuration, but water cooling has an integrated water cooling radiator. Choosing an air cooling radiator of about $15, the radiation effect of an integrated radiator of about $40 is not much different.

7. The bigger power supply is better  

The power supply is less than the sum of the power required by all hardware, and the computer will restart. But the power supply exceeds the total power consumption of all hardware, and it is nothing more than the power budget. Under normal circumstances, the best power supply is the sum of the power consumption of all hardware plus 100W is the most suitable, here is the rated power of the power supply, not the peak power. The power supply is very large, generally in order to consider upgrading the graphics card in the future. If you do not consider upgrading the graphics card, it is generally not necessary to match it too much.

8. Graphics card memory bit width is as large as possible
The graphics card memory bandwidth is not the factor that determines performance. The speed of the graphics card is mainly determined by the graphics processing chip (GPU) of the graphics card, which is determined by the quality of the graphics chip. For example, GTX1060 3G graphics card and GTX1050Ti 4G, many people think that GTX1050Ti 4G is better, this is wrong. Regarding the performance of the graphics card, we can refer to the latest graphics card ladder diagram.

9. Memory dual channel with stronger performance than single channel memory
A single channel of memory refers to one memory, while a dual channel of memory is composed of two or more memories. Then the dual channel memory performance is stronger than the single-channel memory. If the nuclear display is installed, especially the Ryzen platform. it is recommended to improve the performance of the dual channel memory. If it is a stand-alone installation, then memory dual channel or single channel is not that important.

10. The more CPU cores or threads, the higher the performance.
The performance of the CPU is not limited to the number of cores or the number of threads, but depends on the core parameters such as architecture, production process, frequency, and cache.
