Please refer to the following list to know what memory your computer has installed and what memory you want to buy. If you don't know which memory is suitable for your computer, please use the software test to see what memory your favorite machine needs Enter "CPUZ download" in Baidu search bar to search for a CPUZ software (download it and decompress it). After running the software, look at the "maximum bandwidth" column of "SPD" option, and you will see "PCxx00", As follows: PC2100 is DDR 266 memory, PC2700 is DDR 333 memory, PC3200 is DDR 400 memory, PC24200 is DDR2 533 memory, PC24300 is DDR2 533 memory, PC25300 is DDR2 667 memory, PC26400 is DDR2 800 memory, PC38500 is DDR3 1066 memory, PC310700 is DDR3 1333 memory, PC312800 is DDR3 1600 memory, PC417000 is DDR4 2133 memory, PC419200 is DDR4 2400 memory, PC42666V is DDR4 2666 memory The memory DDR, DDR2, DDR3 and DDR4 are not common to each other, and the socket is also different. You can't force them into the memory by bowing, so as not to damage the memory and motherboard. Remember If the memory appears: blue screen, crash, restart, alarm sounds for a long time, please operate one by one according to the following methods. If not, it is determined that it is incompatible.Try the following methods:1. The memory is not plugged in properly, or the golden finger is oxidized. Wipe the memory gold finger with an eraser and then insert it again, or replace the socket2. The memory slot is dusty or oxidized. Clean it with a brush and plate washing water (just brush it without plate washing water)3. The memory is incompatible. Try changing the memory4. If the CMOS is not discharged and the factory setting is settings, it may be normal (remove the motherboard battery and then install it back)5. If the motherboard is incompatible with the CPU. Try changing it
