Please refer to the following list to find out what memory your computer has installed and what memory you have to purchase. If you don't know which memory is right for your computer, use a software test to see what memory your computer needs. (In the Baidu search bar, enter: "CPU-Z download" search for a CPU-Z software download, decompress), after running the software, look at the "maximum bandwidth" column of the "SPD" option, you will see "PCxx00", as follows: 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 If the memory appears: blue screen, crash, restart, alarm sounds, please follow the following methods one by one. If these methods don't work, then it is not compatible. 1. The memory is not inserted, or the gold finger is oxidized. Wipe the memory gold finger with an eraser and reinsert it, or change the slot; 2. The memory slot is dusty or oxidized. Wash it with a brush. (it will be done without washing with water) 3. Memory is not compatible, try to change the memory. 4. CMOS does not discharge and restore the factory settings, maybe it is normal (the motherboard battery is taken down, and then installed back). 5. The motherboard is not compatible with the CPU, change the CPU.
