How to Upgrade an Old Computer

Oct 26, 2022

Whether it is a notebook or a desktop computer, the upgrade of accessories is also a problem that often concerns people. Unlike desktop computers, notebooks have limited improvement and require a certain amount of hands-on ability. If you are planning to upgrade an old computer, you usually consider three major aspects: CPU, Memory, and SSD.

Which one can significantly improve computer performance and boost the old computer's startup speed?

CPU

Although the CPU is updated every year, and the new generation is significantly improved than the previous generation, the CPU does not have a great impact on the fluency of the operating system. For Windows 10, the minimum requirement for the processor is above 1GHz.

For the definition of old computers, up to 10 years ago (older than 10 years computers did not need to be upgraded), the CPU at that time could still support Windows10. A laptop from 10 years ago was installed with Windows 10 system, which is still enough for ordinary office work and stand-alone games.

If you're looking to upgrade your laptop, you won't consider the CPU at all. The CPU of the notebook is usually welded together with the motherboard, which is inconvenient for general users to disassemble, and personal operation is not recommended. For old desktops, replacing the CPU is basically done together with the motherboard, especially the intel CPU, which basically supports up to two generations of motherboards.

Memory

The increase in memory capacity will definitely improve the fluency of the system. If conditions permit, the larger the memory capacity, the better. For notebooks from about ten years ago, the memory is 2GB and 4GB, four or five years ago, the memory is 4GB and 8GB.

If you are still using the Windows 7 system, 4GB memory is enough but 8GB memory is better. If you are using or want to use the Windows 10 system, it is recommended to start at 8GB, and 16GB is better. (Which one should I choose, two 8GB RAM, or one 16GB RAM?)

When upgrading the memory, it should be noted that it is best to use the memory of the same brand, the same model, the same capacity, and the same frequency. At least it should be of the same capacity and the same frequency so that after forming a dual-channel memory, the performance of the computer can be better improved.

SSD (Solid State Disk)

Compared with CPU and memory, the improvement of computer performance is the biggest after upgrading to SSD. After upgrading the mechanical hard drive used in the old computer to an SSD, the speed of the computer will be more than doubled. (Which one should I choose, SATA, or NVMe?)

The read speed of HDD is lower than 200MB/s, usually 100M/s; the write speed is not more than 100MB/s, usually 60-80MB/s. The read and write speed of SSD (SATA) is generally 500MB/s.

Take the computer boot time as an example. If you use an HDD, it will take about 1 minute to boot the computer. If you use an SSD, it will not exceed 20 seconds.

Wrapping Up

If you want to upgrade an old computer, the SSD must be upgraded. Second, you can upgrade the memory. Upgrading the CPU is not recommended.

If you have any questions about the installation, you can leave a message or private message.
