Talking about why 4G memory can only be used by 3G

        Recently, some netizens often ask 4G memory to show only 3G available. In fact, this problem, many computer enthusiasts have encountered before, this phenomenon will occur in both XP system and Win7 system, that is, our computer is installed 4G memory, but only 3G in the computer properties 3.25G, 3.4G or so available, many netizens are very puzzling, and where is the 1G memory running? In response to the question that many netizens are more confused, this article will reveal the answer. 4G memory only shows 3G available. For this kind of problem, in fact, it is related. The screenshot above shows that there is a problem in the computer property of a 4G memory Win7 system. We will find that 4G memory is only available for 3.4G, which is equivalent to 0.6G memory. The capacity is gone. In fact, there are still many friends whose computers are 4G memory, but the display is available in different sizes such as 3GB, 3.25G or 3.5GB. So what is going on in this matter, and what is caused by it? Let’s talk about it in the following small series. In fact, this problem is normal. It is not a problem of the system itself, but a problem of the number of bits in the system. We know that both XP, Win7 and Win8 have 32-bit and 64-bit systems, which leads to the above situation. 32-bit operating system, and because 32-bit systems are still relatively mainstream, so the above problems are more common. 32-bit system theoretically supports 4G memory, and some of the memory that disappears from it is a memory hole, which is occupied by hardware devices such as hard disk, optical drive, sound card, video card, wireless network card, etc. If there is no such memory space address, the machine is Not working properly. Due to the different hardware configuration of the machine, the allocated memory space is also different. The memory capacity has a display of different sizes such as 2.46GB, 3GB, 3.25GB, 3.5GB, etc. This is why we have seen various types of capacity. The best way to solve this problem is to install a 64-bit operating system that is gradually mainstream. The 64-bit system can solve the problem of insufficient 32-bit memory available capacity. In addition, 32-bit systems can also use some cracking tools, so that Win7 system can also display 4GB of memory available, which may not cause system instability, so it is generally not recommended.
