1个4g内存和2个2g内存使用差异(两个2g内存与一个4g内存哪个好)

With the same capacity of 4GB, everyone prefers to use two 2GB memories instead of one 4GB memory. The reason is that two 2GB memories can form a dual-channel memory, which is better than a single memory. Channel mode has better performance.
The motherboard controls the memory through the memory controller integrated in the chipset, and one memory controller controls one memory channel. Most modern computer motherboard chipsets support dual-channel memory and integrate two memory controllers, so the CPU can address and read data from two memory channels at the same time, which can theoretically double the memory bandwidth. , the data access speed is doubled accordingly, resulting in better memory read and write performance. This is why dual-channel memory is more popular than single-channel memory.

The differences are 3:
1. It is estimated that the price of one is cheaper.
2. If it is expanded later, one slot will be missing.
3. In terms of performance, if the main frequency is the same, one piece of data is better than two pieces of data exchange, which is more stable
Overall, if the quality is no problem, You can’t feel the difference after using it!

Two 2G ones can form a dual channel and the speed will be very fast, but unstable. 4G is more stable but not as fast as two 2G ones
