Item Type: Memory Module Model: DDR Material: PCB Memory Frequency: 400MHZ Memory Capacity: 1GB Compatibility: For AMD Applicable Computer: Desktop Bandwidth: PC-3200 Voltage: 2.6V Pin Number: 184Pin Note: 1. Memory is divided into memory cards, DDR, DDR2, DDR3 models. Check the following list to know which memory has been installed in your computer and which memory you need to buy. If you do not know which memory is suitable for your computer, please use the software test to see which memory your favorite computer needs. After running the software, look at the \"Max Bandwidth\" column in the \"SPD\" option, and 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 DDR, DDR2 and DDR3 memory are not common to each other, and the sockets are different, and you can not force the overlord to insert it, so as not to damage the memory and the motherboard, remember! 2. If the memory appears: Blue screen, crash, restart, and the alarm continues to beep, please use 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 properly inserted, 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 washing water to clean it (if you do not have washing water, just brush it down) c. The memory is not compatible, try another memory. d. CMOS is not unloaded to restore factory settings, it may be normal (the motherboard battery is removed and then put back). e. The motherboard is not compatible with the CPU, try changing the CPU 2 x Memory Module Customers are our top priority.
