Instruction: The memory module is divided into SD, DDR, DDR2, and DDR3 models. Please check the following list to determine which memory module is installed in your computer and which memory module you need to purchase. If you don't know which memory module is suitable for your computer, use software to test which memory module your computer needs. (Download CPU-Z software and unzip it). After running the software, look at the "Maximum Bandwidth" column in the "SPD" option. You will see "PCxx00" as follows: (DDR, DDR2, and DDR3 memory modules are not interchangeable, and the sockets are also different. Do not force it in to avoid damaging the memory module and motherboard, remember!) PC2100 is DDR 266 memory module PC2700 is DDR 333 memory module PC3200 is DDR 400 memory module PC4200 is DDR2 533 memory module PC4300 is DDR2 533 memory module PC5300 is DDR2 667 memory module PC6400 is DDR2 800 memory module PC8500 is DDR3 1066 memory module PC10700 is DDR3 1333 memory module PC12800 is DDR3 1600 memory module Specifications: Product Type: 4GB 800MHz DDR2 Memory: 4GB PIN: 240PIN Frequency: 800MHz Suitable: For Desktop Computer Suitable: For AMD Voltage: 1.8V Bandwidth: PC2-6400 Package Size: approx. 15 * 6 * 1 cm/ 5.9 * 2.4 * 0.4 in Package Weight: 26g/ 0.9oz Package List: 1 * 4GB 800MHz DDR2 Method: If the memory shows: Blue screen, crash, restart, long alarm sound, please do the following. If not, it is considered incompatible: 1. The memory is not inserted properly, or the connecting finger is oxidized. Use an eraser to erase the connecting finger of the memory and then reinsert it, or change the slot. 2. The memory slot is dusty or oxidized. Use a brush and washing water to clean it (If you don't wash the water, just brush it off) 3. The memory is not compatible, try another memory. 4. CMOS is not discharged to restore the factory settings, maybe it is normal (the motherboard battery can be removed and then reinstalled). 5. The motherboard is not compatible with the CPU, try another CPU Note: The product can only be used for AMD motherboards and does not support Intel processors. If the motherboard is equipped with a DDR2 interface and the CPU is suitable for AMD, this product is compatible with your device. However, if the motherboard is too old and the motherboard does not support 4G memory, this product is not suitable for your device. Package List
