is the notebook memory bar universal?

Classic question: Does the notebook memory line be universal?

Answer: Whether the memory bar is universal contains two kinds of situation, one kind of memory and memory compatibility problem, the other is the motherboard and memory compatibility problem. In view of these two situations we introduce separately:

1, two notebook memory general issues

If the notebook belongs to an additional memory upgrade, then the memory strips are usually not generic. This mainly involves memory frequency and memory size, as well as dual-channel issues.

If you add another piece of memory to your notebook, the best guarantee is that the purchased memory will be the same in memory brand, memory frequency, memory type (DDR2 or DDR3) and memory size, so that you can achieve the best two memory compatibility. Of course, sometimes different brands have the same size of memory can be compatible, but there are also accidents, so if you are building dual memory, it is best to ensure that each memory parameters are the same best.

2, memory and motherboard compatibility issues-that is, the old small memory into a new large memory

If you are looking for a new memory bar for your notebook, it is important to note that your notebook board supports maximum memory capacity, memory type (DDR2 or DDR3), and the maximum frequency of memory support, which is largely irrelevant for branding.

Generally speaking, notebook memory can be said to be generic, but also can be said to be not universal, according to your notebook motherboard and the situation. If the motherboard supports DDR3, the maximum support 8G memory, then you can replace the various brands of DDR3 8G to memory memory, this situation we can basically say that memory is universal.

But for a dual-memory bar, it's best to make sure that the size of the two-piece, the brand model, the memory frequency, and the type of memory must be the same, so we can basically say that the memory strips are not universal.

Notebook Memory Upgrade Recommendations: If you want to keep the original memory notebook, want to add a memory to the notebook, it is advisable to buy a same brand, the same model, the same size, the same type of notebook memory. This supports better performance and does not have incompatibilities and facilitates the building of dual-channel memory strips. In addition, if your motherboard large memory support, it is recommended that you buy a larger version of the DDR3 memory, the original old memory can be removed.
