The initial installation is not awkward, scientific allocation of budget to create a perfect host!

With the development of technology, computers are no longer an unattainable luxury. With its rich functions, it has become an indispensable tool for thousands of households. It can surf the Internet and relax, and it can help you at work. . There is a significant difference between computers and other home appliances, that is, it does not have a standard configuration. Home appliances such as TVs and refrigerators have uniform standards, and computers can be flexibly matched according to different needs of users.

The way to buy a computer can be divided into two types. One is to choose a brand computer. This kind of purchase method is the most labor-saving. It can be used after being bought. The operating system has been installed, but the brand machine has a disadvantage that it is the space for hardware selection. Rarely, some accessories may not meet the needs of users, and the price is not high. Another way is to buy accessories and accessories, users can choose the appropriate accessories according to their actual needs, the same configuration is cheaper than buying brand machines. However, picking up the accessories is a big challenge for the novice. Here I will introduce some tips for allocating the installed budget.

First of all, before the installation, be sure to make a budget according to your own use, do not temporarily increase the budget when installing the machine. Generally speaking, if it is a computer for office use and home Internet access, the host budget is about $3,000 or so, and the game users can increase to more than $ 5,000 . Of course, if the game player has sufficient budget, he can directly select new products with strong performance to buy and buy. Yes.

Determine the total budget of the host, the next is to allocate budget for various hardware. Let’s take a $5,000 gaming computer as an example. Generally, the motherboard and CPU can account for 35-40% of the total budget, which is about $2,000. The graphics card can account for 30% of the total budget, which is about $1,500. Users who do not play games can use the core graphics card to save the budget to other accessories without purchasing a graphics card. The rest of the budget can be used to purchase memory, hard drives, and chassis power.

How to choose a computer CPU, don’t be pitted again!

Everyone knows that the CPU is the brain of the computer and is a very important part of the computer. Therefore, when purchasing, you must choose a high-quality CPU, but many computer whites are recommended by the manufacturer’s brother, you must know people. It is necessary to maximize the benefits, and the price/performance ratio that is not necessarily recommended to you is the highest. The following small series takes everyone to understand the situation that CPU purchase should pay attention to.

1, i7 must be better than i5: Some friends may say, of course, buy a computer to buy i7 or more, because the performance of i7 is definitely better than i5 and i3. So i7 must be better than i5, obviously not so simple. The so-called i5, i7 are just a rough classification of Intel’s CPU models, they do not represent the absolute ranking of processor performance. Because Intel’s processors are divided into multiple series for different devices, the performance and power consumption differences between different series are huge. If it is the same generation of products, i7 will generally be better than i5 and i3, then what is the same generation? For example, the i7-8700 CPU and i5-8500, the first digit of the last four digits, represents the first generation of CPU, these two are the same generation, so the natural i7-8700 is stronger than the i5-8500.

2, the more the number of cores, the better? When you buy a computer, the general sales staff will say that our CPU is a few core cores, although the core number is an important reference for the CPU, but the core number does not necessarily represent all. For a CPU, whether to support Hyper-Threading Technology, default frequency, maximum core frequency, whether to support overclocking and other parameters are very important reference content. Therefore, in the process of purchasing a processor, it is unscientific to judge the quality of a CPU only by the number of cores. It should be noted that due to the different architectures of the products, Intel and AMD are different for the processor’s main frequency standard and cannot be directly used for horizontal comparison.

 

How to choose pc host power supply

I believe that many diy enthusiasts only pay attention to the CPU and graphics card when assembling the computer, and often ignore the power supply. In fact, the power supply as a small heart for the computer to provide energy to each component directly affects the normal operation of each component. How do you choose a power source in the times?

The role of the power supply, good power supply can be, (cpu, main card, video card), etc., the components provide a stable output, can reduce the voltage instability, can extend the life of the cpu and graphics card and other components, said so many now Share how to choose a quality power supply.

Brand selection, nowadays there are many power supply brands in the market, which can be described as dazzling. First of all, we must choose a big brand. The big brands are very solid in workmanship and materials. The so-called brand is also a guarantee of quality, not to be cheap or to be agitated by businesses. Choice, so as not to cause trouble, I have seen a lot of computers because of the choice of small brands or even brand-name power, resulting in the computer can not boot, crash, automatically restart, and even burned the motherboard and so on.

Because of the need to purchase, according to their current configuration and future needs to choose the power of the power supply, simply speaking, if the general configuration does not have a single display, but usually at home, rated 250W enough, if the belt is independent, at least rated at More than 300W, we must pay attention to its rated power, not the maximum power, but also consider a series of problems such as computer upgrades in the future.

Is it necessary to choose a gold power supply?

80plus, bronze, silver, gold In fact, 80plus is only a certification standard for power conversion efficiency. The conversion efficiency of copper, silver and gold is improved in turn, more energy-saving and power-saving, and there is no direct relationship with power quality. Conversion efficiency without certification is not necessarily low. If you have sufficient funds, you can choose 80plus certification, because after passing the certification, there are multiple guarantees, that is, the higher the level, the more power is saved.

1, low-end office home: the use of I3-class CPU, the use of nuclear display or a discrete graphics card not higher than 1,000 yuan, low power, recommended power supply rated about 300W.

2, the mid-end game platform: the use of quad-core processor + no more than 2,000 yuan of discrete graphics, you can play online games and play some small 3D games with less special effects, the whole machine power consumption is about 200-300W It is recommended to select a rated 450W~650W power supply.

3, extreme fever host: I7 level CPU and 2000 yuan or more of independent graphics, power supply recommended 500W start, this part of the players are generally experienced DIYer, power requirements are very clear, more fancy is the quality of the power supply, I believe that power supplies like the ultimate firepower 80PLUS Platinum certification can get their level.

Which computer host is playing, the performance is high, and the computer runs particularly smoothly!

The server is so powerful, why no one directly used it as a computer host?

With the continuous development of the economy, more and more enterprises and companies are emerging. In the daily operation of these enterprises, it is very important to have a device. It is a server. The server can provide a lot of services for enterprises or companies, such as data storage, data migration, content sharing, etc., and the server’s hardware configuration is powerful, powerful, and can be used for several days on home computers. Faced with such a server, one can’t help but have a question. Why is the server so powerful and no one uses it as a computer?

1, the price is expensive

We all know that the hardware configuration of the server is very powerful, the processor, memory, hard disk, etc. are much higher than the home computer, which also makes the price of the server remain high, the price is basically maintained at the level of tens of thousands. The price of a home computer is much lower, and it takes only a few thousand pieces to assemble a computer that can play games and work.

2, the server is noisy

I believe that people who have entered the IDC room have seen how much noise the server has. Because of the high performance of the server configuration, the requirements for heat dissipation are also very high, which causes it to generate considerable noise when it is working. Imagine you are using such a noisy server, and are you in the mood to play games?

3, the graphics card category is different

Most of the graphics cards installed on the server are graphic graphics cards, mainly dealing with professional image work. The optimization and support for the game is very weak. It is not as comfortable as playing a game with a separate graphics card on a home computer.

Recommended exquisite office utility computer host configuration

The configuration is as follows:

CPU: i3 8100

Motherboard: ASUS Saint H310M-D3V

Memory: Kingston 8G

Hard disk: Western Digital 1T

Solid state: Western Digital 240G

Graphics Card: Colorful 1050TI GAMING 4G

Chassis: Cool Cool Extreme Q300L

Power: Huntkey 500W

Radiator: Qiao Sibo 120 Water Cool Angel Eye 601 Edition

This set of configuration is extremely practical, taking into account office and games, work and entertainment.

The flag of Shengqi is the new brand of Asus. This motherboard is the ASUS 310M-K vest, which is extremely cost-effective. Kingston memory has good compatibility. Xiaobian strongly recommends it. (Buy Kingston memory must be polished, or it is easy to buy fakes.)

The hard disk is based on Western Digital’s solid state and mechanical disks. Solid-state prices are now falling, and 240G SSDs are a must. Colorful this 1050TI is a white fan looks very beautiful, the only regret is that the independent power supply is canceled.

Cool and supreme, this Q300L chassis is compact and cool.

Will AMD bid farewell to independence? AMD’s new APU exposure: give up alone!

Recently, the AMD next-generation Ruilong 3000 series desktop-class mainstream processor broke the news is very exciting, up to Ruilong 9 down to Ruilong 3 seems to use 7nm, high-end Ruilong 9 3850X has up to 16 core 32 Threads, and the frequency can be dynamically accelerated to 5.1GHz, the entry-level Ruilong 3 3300X and the Ruilong 3 3300 will also go up to 6 core 12 threads and maintain 50W of thermal design power.

Previously, it was reported that the Ruilong CPU and APU will be released together. In terms of APU, the Ruilong 3000U series for thin and light versions is likely to adopt 12nm Zen+, which is one generation behind the desktop level, and the new model will only increase the frequency. It may be necessary to use 7nm for the APU.

According to the new news, AMD is preparing for the new Ruilong 3 3300G and Ruilong 5 3600G processors. The Ruilong 3 3300G has 6 centers and 12 threads. Its center frequency scale is 3.0~3.8GHz, and the thermal design power consumption is only 65W. Its integrated Vega architecture will add 15 more computing units, or 960 stream processors, for an estimated price of $129.99.

Ruilong 5 3600G will reach 8 centers and 16 threads, the center frequency scale will come to 3.2~3.8GHz, and the thermal design power consumption will be increased to 95W. The Ruilong 5 3600G integrated Vega architecture will add 20 computing units, which is 1280 stream processors, and the price is estimated to be $199.99. Visual inspection can almost reach the level of the RX560 graphics card, and it is really not possible to use a discrete graphics card.

However, the Ruilong 3 3300G and the Ruilong 5 3600G may not be released until the third quarter of this year. The recent CES 2019 exhibition may not have their appearance. In any case, I am still very much looking forward to it. Whether it is a desktop CPU or a mobile APU, AMD may really have to turn over this year. The arrival of 7nm Zen2 products will inevitably cause some turmoil in the market.

Can the DIY fanatic “liquid nitrogen gun” be suitable for home computer mainframes?

Many small partners are always trying their best to improve the performance of their computer hosts when they are doing DIY transformation on their own computer mainframes. Some methods are also varied, and even some limit methods are wonderful. I will take you today. Look at the most current “liquid nitrogen gun”. Since there is a gun in the name, it is definitely not as simple as domineering. The name of the gun is definitely the meaning of firepower, but today’s “liquid nitrogen gun” is not powerful. However, the cold is strong, for friends who understand liquid nitrogen, it may be known that the temperature of liquid nitrogen at room temperature is -196 ° C, this time know why his cold power is strong.

Liquid nitrogen refrigeration computer

Having said that, there may be many friends who are thinking about what the “liquid nitrogen gun” means. In fact, it is a kind of gameplay in the computer DIY overclocking world, that is, let the computer reach the limit operation overclocking, and then use liquid nitrogen to cool, because the liquid The boiling point of nitrogen is -196 ° C. Under normal atmospheric pressure, if liquid nitrogen is formed below this, when liquid nitrogen is exposed to room temperature, it will boil rapidly, thus achieving the principle of rapid cooling and cooling, so many DIY overclocking partners use this principle to play extreme overclocking and physical cooling of CPU and GPU, and because of the timeliness of rapid cooling, they are often referred to as “liquid nitrogen guns” by many madman DIY friends.

Liquid nitrogen computer refrigeration
So how can we achieve liquid nitrogen refrigeration? First, we have to prepare a tank for storing liquid nitrogen. The bottom surface should be flattened and fixed on the main board. Then we can make an insulation layer. There are many materials for the insulation layer. Here, why do you want to make insulation layer, which is the same as the insulation layer of the freezer. Even if it is cold inside, it will not be frosted outside, or you think about it, the CPU inside is cooling down, but the outside of the liquid nitrogen tank is frosted. Once the melting board is connected, it is necessary to keep the heat, so the insulation must be done well. In a picture of the top of the board on the picture above, like a barrel, it will continue to take “smoke” after adding liquid nitrogen. I think this is the true meaning of the “liquid nitrogen gun”, or the source of the name.

Computer liquid nitrogen refrigeration
So let’s return to the theme, why is liquid nitrogen a favorite of overclockers? For extreme overclockers, it is clear that air-cooling and water cooling can no longer meet their cooling needs, so the highest level of DIY heat dissipation is liquid nitrogen heat dissipation, liquid nitrogen The temperature is -196 ° C, which can instantly reduce the temperature, and has a very strong suppression effect on the extreme overclocking CPU temperature. And as long as the liquid nitrogen is not lost, there is almost no room for temperature rise. In one of the most important things, liquid nitrogen is absolutely rolling-type refrigeration for the heat dissipation of the computer. Some people have done experiments, which is overclocking in the computer CPU. At the time when the eggs can be fried, the liquid nitrogen is added instantaneously. As a result, the CPU stops the food in just a few seconds, and the temperature is almost vertically lowered. Perhaps it is because of the principle of liquid nitrogen’s limit cooling. The favorite of DIY overclockers.

The mainframe of the computer, it will be very embarrassing to choose!

In the computer host DIY, all the hardware is selected, the chassis must be the “big thing” that you finally considered.

For most people, the role of the computer case is to provide a bracket to wrap the motherboard hard drive power and other hardware in an orderly manner, so that they can live and work in peace and contentment.

So what do you need to pay attention to when choosing a chassis?

First of all, the choice of the chassis should take into account the future expansion of the hardware. In addition to some obvious configurations such as the hard disk bit and the usb hole, the most easily overlooked is whether the space of the chassis matches the size of the discrete graphics card. This will not only affect the future upgrade of the graphics card, even if you are purchasing hardware on the Internet to assemble the computer, the graphics card that may be bought back is too big to fit into the chassis, it is very embarrassing. Generally, the larger chassis will be better. If it is a small mini chassis, this problem cannot be ignored. The graphics card with better performance can hardly be loaded.

So when choosing a mainframe, you must consider this issue.

Second, an important role of the chassis is to prevent radiation. The biggest radiation in the computer mainframe hardware is the CPU and the two major power consumers. They are not only generating a large amount of heat during high-frequency operation, but also generating the largest amount of electromagnetic radiation. If they are not guarded, they will accumulate on the human body for a long time. The damage will be hard to estimate.
