Xiede DDR3L RAM Portable Wear Resistance Anti Corrosion Heat Dissipation Laptop RAM1600Mhz 8GB Item Type: DDR3L RAM Material: PCB Model: DDR3L Memory Capacity: 4GB/8GB Memory Frequency: 1333Mhz/1600Mhz Bandwidth: PC3-10600/PC3-12800 Voltage: 1.35V Pin Number: 204PIN Compatibility: Fully Compatible (for Intel/AMD) Applicable Computer: Laptop Note: The memory is divided into storage card, DDR, DDR2, DDR3, DDR4 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. (Enter in the Baidu search bar: "CPU-Z download" to search for a CPU-Z software to download and unzip), after running the software, look at the "Max Bandwidth" column of the "SPD" option, you will see "PCxx00", as follows: PC-2100 is DDR 266 memory PC-2700 is DDR 333 memory PC-3200 is DDR 400 memory PC2-4200 is DDR2 533 memory PC2-4300 is DDR2 533 memory PC2-5300 is DDR2 667 memory PC2-6400 is DDR2 800 memory PC3-8500 is DDR3 1066 memory PC3-10700 is DDR3 1333 memory PC3-12800 is DDR3 1600 memory PC4-17000 is DDR4 2133 memory PC4-19200 is DDR4 2400 memory PC4-2666V is DDR4 2666 memory Memory DDR, DDR2, DDR3, DDR4 are not common to each other, and the sockets are also different, and don't insert it forcibly, so as not to damage the memory and motherboard, remember! If the Memory Appears: Blue screen, crash, restart, and the alarm keeps beeping, please operate according to the following methods one by one. If it does not work, it is determined that it is not compatible. You Can Try the Following Methods: ⒈The memory is not inserted well, or the gold finger is oxidized. Use an eraser to erase the memory finger and then re-insert it, or change the slot; ⒉The memory slot is dusty or oxidized. Use a brush and wash board water to clean it (if you don’t have board wash water, just brush it down) ⒊The memory is not compatible, try changing the memory. ⒋CMOS is not discharged to restore the factory settings, maybe it is normal (the motherboard battery can be removed, and then put it back). ⒌The motherboard is not compatible with the CPU, try changing the CPU
