Don’t waste an old computer upgrading these interfaces

Can't I upgrade my old computer except for replacement parts? In fact, many old computer interfaces have been idled. If you make good use of these old interfaces, upgrading is not necessarily just a replacement. It is more convenient to do an addition upgrade.

Memory slot

If you don’t understand it, start with the simplest memory slot. ATX/MATX desktop motherboards generally support 4 memory slots (some MATX and all ITX motherboards only have two), I believe it is extremely Few people can fill up 4 RAMs. Isn't this a good way to expand the RAM?

It should be noted that desktop computers are mainly DDR3, and DDR4 should not be mistaken (the motherboards before 2016 are DDR3 memory); notebooks are a little more complicated. In addition to the difference between DDR3 and DDR4, DDR3 also has a low-voltage version, DDR3L, The voltage is reduced from 1.5V to 1.35V, and the two cannot be inserted at the same time (some notebooks support two specifications, but cannot be mixed)!

There is also a commonplace question. The memory is based on the lowest frequency of all memory as the benchmark. Be careful not to buy the wrong one!

PCIE slot

The biggest advantage of a desktop computer is that it has very rich scalability. The most important point is the PCIE interface. Through this standard expansion slot, there are so many things that can be expanded.

For example, some old computers give a 100M network card. After upgrading to a 100M bandwidth, the network card becomes a bottleneck. The PCIE network card can be upgraded to a gigabit LAN interface, and the problem can be solved at once; or various solid state PCIE adapters Hard disk cards, such as M.2 to PCIE, allow the computer to directly enjoy the high-speed disk performance experience brought by M.2, and the progress of reading the disk is definitely another world.

After talking about the PCIE interface of the desktop, let's talk about the interface of the notebook. Although the integration is very high, the old notebook is not without expansion interfaces. The most important thing is the MSATA and mini PCIE slots (the new version does not have MSATA, instead it is M.2).

The MSATA slot is actually exactly the same length as the miniPCIE slot. If you can’t tell the difference, you can tell by the printed fonts under the slot—miniPCIE is printed with the words WLAN, while the MSATA slot does not. MSATA is used to expand the solid state drive is a good choice for upgrading old notebooks. The performance is equivalent to the ordinary SATA interface. The biggest advantage is that it occupies the original hard disk space. In this way, the traditional hard disk is used as the data disk and the MSATA solid state disk is used as the system disk. !

In my opinion, the ultimate notebook upgrade is that mini PCIE is connected to an external graphics card. This DIY upgrade expansion device can be connected to the desktop's independent graphics card through the mini PCIE interface. The graphics performance of the notebook will be extremely high. Great improvement, interested friends can search for a treasure.

Finally, there are relatively new notebooks. Many products currently have a Thunderbolt interface. Through this interface, you can easily expand the USB interface, wired network card, card reader, and even external independent display!
