What should be the upgrade of the old computer? The speed of desktop updates is far less than that of mobile phones, tablets, and even notebooks. It is often a computer that is still in service for four or five years. Although the hardware performance is not as good as before, but with a pity of throwing away, a waste of waste, after a little upgrade, you can still fight for three or five years. No. Older computers are not worth the second-hand sales. Of course, the upgrade should pay attention to the money, what should we upgrade?
Reasonable evaluation: In the end, your PC should not be upgraded.
DIY is a systematic project. It is not a dare to say that it is a one-size-fits-all move, but it is also a reasonable mix of hardware and compatibility to ensure smooth running of the platform. For example, if your old computer only supports DDR2 memory, you can buy a DDR3 memory; if you originally saved money, you will use a power supply with ultra-low power rating, even if the power supply of the external graphics card is missing, then upgrading the graphics card is to find abuse, and it is not interesting. As with some mini-platforms, there are no PCI-E graphics slots, which greatly limits the scalability.
Ordinary users should not be rushed to go to the hospital for medical treatment. They need to analyze the short board of their old platform and make a reasonable match according to the principle of balance. According to the needs of users, a reasonable solution to achieve the goal at low cost. Here I suggest that if your computer is still in the era of Pentium 4, Pentium D, still using DDR2 memory, SATA2.0 interface G41 and other motherboards, then I strongly recommend that you buy one again.
The question is: What should be the most limited budget?
As mentioned earlier, DIY is a system engineering. To change the CPU, you must change the motherboard and change the fan. After replacing the motherboard, do you need to consider whether the memory specifications are compatible? Change the graphics card, found that the power supply can not keep up, often have to change the power; even if the power supply is enough, but also consider the length of the graphics card, the old chassis is compatible, buy back can not fit the chassis, want to cry can not stop. And what should we upgrade with our limited budget? The advice I gave was SSD+ memory.
Insufficient memory capacity: often makes you crazy
Microsoft announced that the XP system will stop patching, which means official farewell. Win7 has become popular, Win8 is on the road, Win10 has also appeared, the three systems in the case of downtime take up more than 1GB of memory, just a lot of old platform memory capacity is only 2GB, such equipment for the old computer is definitely a torment.
The most effective way to improve system resources is to upgrade the memory capacity. Memory is the bridge between the hard disk and the CPU. In multitasking or big data reading, small memory capacity will cause the data to be processed to "queue the equal sign", so opening a program often requires waiting for ten or more seconds. Another example is online games, stand-alone games, which take up more memory. If there is no large-capacity memory support, regular cardots are enough to make people crazy.
So 4GB of memory is the most basic choice, 8GB is the current mainstream. Sufficiently large memory ensures that the computer can run smoothly when it is open, and applications such as games, movies, and professional software loading can be used. Do you want to consider the performance of the memory? Look at the mechanical hard drive of your old computer, you know that the performance of the current memory is absolutely more than enough.
Upgrade the hard drive: the most suitable for the original upgrade
If you upgrade the memory only because the capacity is not enough, but upgrade the HDD to SSD, it must be the most in line with the original intention of our upgrade. SSDs have only begun to emerge in recent years, but most of the computers used in the past three or five years are still in the HDD stage. The operation of the mechanical hard disk is mainly driven by the mechanical drive head. It must be moved to the access position on the fast rotating disk. The whole process is quite cumbersome, and the performance bottleneck cannot be broken, which becomes the biggest bottleneck of the whole machine.
The SSD is without any mechanical components and requires no complicated mechanical movements to quickly and accurately access any position of the drive. The random data access time of SSD is 0.1ms or shorter, while the traditional 2.5-inch or 3.5-inch HDD takes about 10-14ms, and SSD data access is 100 times faster than HDD.
The emergence of SSD is to break the bottleneck of the hard disk, effectively reduce the time for loading programs and resources into the system, greatly shorten the delay of the system, and improve the speed of the whole machine. The speed mentioned here includes not only the boot speed, but also the loading speed of various applications can be greatly improved. In the loading of large game scenes, etc., it may make you completely forget that your computer was five years ago.
Recommended upgrade package: ADATA SP550 240G + DDR3-1600 8G single strip
Here, I recommend the ADATA SP550 240G SSD plus the DATA DDR3-1600 8G memory single. Why is this recommended?
First, since it is an old platform, it is impossible to consider expensive high-end SSDs, and it is advisable to choose an entry-level SSD. SP550 is the new entry-level SSD launched by ADATA. The performance is good. At present, the e-commerce offer is only 449 yuan, and the price is very prominent.
Second, the price of SSD is getting cheaper and cheaper. The capacity of 120G/128G is too limited. There are few systems installed, and it is most suitable to purchase 240/256G capacity SSD.
Third, the current mainstream frequency of DDR3 memory is 1600MHz, there is no need to excessively pursue high frequency and high performance, the old platform can not be used, in addition, now DDR3-1600 memory cabbage price, a single 8G one step in place to solve the problem of insufficient memory capacity.

a('show4');to sum up:
This time I recommend the dual-gun combination of memory and SSD--Weigang SP550 240G+ DDR3-1600 8G single. The upgrade performance is outstanding, and the affordable SSD can speed up the system, coupled with the mainstream frequency and large-capacity memory, not only can the system smoothly escort, but also bring the overall experience of the old platform to a new level.
