Do you really need to choose Dual-channel memory (RAM)?

DIY players will often encounter this or that problem, especially in terms of memory, there will be a lot of new ideas looking forward and backward: For example, your motherboard only has two memory slots, should you pay for 16G or dual 8G memory?


Do you really need to choose Dual-channel memory (RAM)?


If the budget is enough, it better to select the motherboard with 4 memory slots, and then add 4x16G memory sticks. 

However, you have to make a choice if the budget is limited.


Simply put, the difference between different memory ratios is that the price of a single 16G memory is cheaper than the price of two 8G memories, and it occupies one less memory slot.

The advantage of two 8G memories is that dual channels can be turned on to obtain a certain degree of performance improvement.

Let’s popularize a knowledge first, that is, when the computer is working, the CPU directly exchanges data with the memory.

The larger the memory capacity, the more files can be placed for processing, providing more space when exchanging data with the CPU. , dealing with large software and multitasking will be easier.

In addition, the reading and writing speed of memory is also related to the running speed of the computer.

Compared with single-channel memory, dual-channel memory has double the bandwidth, and the reading speed of memory can be faster, although it cannot actually achieve the obvious effect of doubling. But when using the nuclear display, you can clearly feel the difference.


It needs to be emphasized that dual-channel memory can achieve twice the result with half the effort for the nuclear display, and the frame rate of many games can be improved by 50% or even higher, while for the independent display, the dual-channel frame rate increase is It is very limited, so players who use independent graphics don’t insist on dual channels.


After understanding these knowledge points, we can easily remember the conclusion. If you are using a nuclear display and are not equipped with a discrete graphics card, then you must choose dual 8G to open dual channels, especially for games and image processing. Requesting users are given priority over all other factors.


If you are using a discrete graphics card and the motherboard has 4 memory slots, then dual 8G memory is also the first choice, because 2 memory slots are reserved for future upgrades.


However, if the motherboard has only 2 memory slots, and you are worried about future memory upgrades, you can choose a single 16G memory in the case of using the independent display, because the performance improvement brought by dual-channel memory is not obvious.

In addition, I would like to remind everyone to pay attention to memory compatibility when purchasing heatsinks.

Some large-sized heatsinks will crowd the memory slots after installation. If your motherboard is reduced by 2 memory slots, then Just change the hardware.
