The memory is divided into memory card, DDR, DDR2, DDR3 models. Please check the following list to know what memory has been installed in your computer, and what memory you need to buy. The memory DDR, DDR2, and DDR3 are not common to each other, and the sockets are different, and you can't force to insert it in, so as not to damage the memory and the motherboard, remember PC2100 is DDR 266 memory PC2700 is DDR 333 memory PC3200 is DDR 400 memory PC4200 is DDR2 533 memory PC4300 is DDR2 533 memory PC5300 is DDR2 667 memory PC6400 is DDR2 800 memory PC8500 is DDR3 1066 memory PC10700 is DDR3 1333 memory PC12800 is DDR3 1600 memory 2. If the memory appears: blue screen, crash, restart, alarm keeps beeping, please operate one by one according to the following methods. If fails, it is determined not compatible. a. The memory is not inserted well, or the gold finger is oxidized. Use an eraser to erase the memory gold finger and then reinsert it, or change the slot. b. The memory slot is dusty or oxidized.
