1. Open "Start" menu, click "Run" button
2. Enter "CMD" in the pop-up window, then confirm or press ENTER.
3. Enter "Wmicmemphysical get Maxcapacity" in the command window and hit enter.
4, then the computer will give a string in kilobytes units of the number. We'll convert this number to our common GB units.
The conversion method is: "Obtained number/(divided by) 1024/(divided by) 1024"
Figure: My computer gets the number of 16777216K bytes, then I divide by 1024 and divided by 1024, it is equal to 16GB. In other words, the hardware of my computer, with the system I installed, the maximum capacity of memory is 16GB.
Precautions:
1, the operating system is different, the motherboard is different, then they support the maximum memory capacity is also different
2, Win 32-bit system, up to 3.25G of memory support, no matter how much your motherboard support, but the 32-bit system can only support about 3.25G of memory
3, if you installed more than 4G or just 4G of memory, please install 64-bit operating system, in order to obtain greater memory support, speed up the processing speed of personal PC.
