Item Type: Memory ModuleModel: DDR4Material: PCBOptional Memory Capacity: 8GB/16GBMemory Frequency And Corresponding Bandwidth: 2666Mhz (PC4-2666V), 2400Mhz (PC4-19200)Voltage: 1.2VPin Number: 288PINCompatibility: Full compatible (for Intel/AMD)Applicable Computer: DesktopNote:1. 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. If you don't know which memory is suitable for your computer, please use the software test to see what memory your favorite computer needs. After running the software, look at the "Maximum Bandwidth" column of the "SPD" option, and you will see "PCxx00", as follows:PC2100 is DDR 266 memoryPC2700 is DDR 333 memoryPC3200 is DDR 400 memoryPC4200 is DDR2 533 memoryPC4300 is DDR2 533 memoryPC5300 is DDR2 667 memoryPC6400 is DDR2 800 memoryPC8500 is DDR3 1066 memoryPC10700 is DDR3 1333 memoryPC12800 is DDR3 1600 memoryThe memory DDR, DDR2, and DDR3 are not common to each other, and the sockets are different, and you can't force theoverlordto insert it in, so as not to damage the memory and the motherboard, remember 2. If The Memory Appears: Blue screen, crash, restart, and the alarm keeps beeping, please operate according to the following methods one by one, if not, it is determined that it is not compatible.Try The Following Methods:a. The memory is not inserted well, or the gold finger is oxidized. Use an eraser to remove the memory finger and then reinsert it, or change the slot;b. The memory slot is dusty or oxidized. Use a brush and wash water tocleanit (if you dont have wash water, just brush it down)c. The memory is not compatible, try another memory.d. The CMOS is not discharged to restore the factory settings, it may be normal (the motherboard battery is removed, and then put it back).e. The motherboard is not compatible with the CPU, try changing the CPU 1 x Memory Module
