Due to the epidemic, the rise of home office has led to a surge in demand for notebooks. Coupled with the start of autumn school soon, many small partners have ushered in a new wave of replacements. Among the major installations, the motherboard, CPU, graphics card, and memory are more concerned, and most of the choice of memory is only concerned with its model. In fact, the installation of memory is also particular and cannot be installed casually.
First of all, we suggest that we need to judge whether our memory sticks need to be upgraded. You can open the task manager to check, if we are running games or using software, the memory occupancy rate exceeds 70%, then we need to consider upgrading the memory.
When upgrading the memory, first confirm whether the computer needs to change or add memory. Not all computers are suitable for installing additional memory modules. Adding memory requires a free card slot in the computer. Some computers may only have one memory module slot. But considering portability, most notebooks generally only have two slots. Although your motherboard supports them, only two are soldered. Therefore, the actual situation is subject to the disassembly.
First of all, when adding a new memory module, try to choose the memory module products of the same brand and similar specifications as the original memory module. Excessive differences are likely to lead to compatibility, or have a counterproductive effect on the improvement of computer performance;
For example, a single memory can be inserted casually, and two memories can be inserted into 2 or 4 slots. Considering compatibility issues, it is best to use memory of the same brand, the same model, and the same capacity. If the 4G+8G combination totals 12G, the result is that 4G+4G is a dual-channel mode, and 4G is a single-channel mode. This situation is a flexible dual-pass mode, also called asymmetrical dual-pass mode. In addition, there may be some compatibility issues, such as blue screen of death; in the case of three memory sticks, on the basis of the dual-channel insertion method, the third one is inserted in the first slot. In this case It is 2 memory dual-pass, 1 memory single-pass.
Secondly, it is also related to different motherboard sizes. Each computer motherboard has an upper limit of memory capacity. Different chipsets, brands, and models of motherboards have different upper limits for memory capacity. Then, there is a restriction from the system. The 32-bit version system only supports the use of up to 4G memory, and the memory beyond 4G cannot be used even if it can be identified, while the 64-bit system does not have this problem.
