Built-in high quality chips for stable performance and high speed operation. The high memory speed of 800MHz increases the speed of your computer and brings convenience to your life. 1G large capacity provides powerful performance and storage for everyday reading and writing. High-quality circuit module board, effectively avoiding corrosion and wear, durable and easy to carry. : Model: DDR2 Memory Frequency: 800MHz Memory Capacity: 1G Compatible: Compatible with for AMD platform Bandwidth: PC2-6400 Voltage: 1.8V Pin Number: 240pin Package list: 1 * Memory Bank Note: Memory is divided into SD, DDR, DDR2, DDR3 models. Please check the following list to know 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 the software test to see what memory your love machine 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: 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 Memory DDR, DDR2, DDR3 are mutually exclusive to each other, and slot sockets are not the same, and can not be forced to insert, so as not to damage the memory and motherboard, remember! If the memory appears: blue screen, crash, restart, alarm sounds, please follow the following methods one by one, if not, it is determined that 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 and board-washing water (If there is no board-washing water then brush it.) 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, try to change the CPU.
