Item Type: Memory Module Material: PCB Color: As Shown Model: DDR2 Memory Frequency: 533MHz Memory Capacity: 2GB Compatible: For AMD Dedicated Memory Applicable Computer: Desktop Bandwidth: PC2-4200 Voltage: 1.8V Number of Pins: 240 Pins Note: 1. Memory is categorized into SD, DDR, DDR2, and DDR3 models. Please check the list below to identify your computer's installed memory and the type you need to purchase. If unsure, use software to test and determine your computer's memory requirements. Look for the 'Max Bandwidth' column in the 'SPD' option, which will show '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 interchangeable, and their slots are different. Do not force installation to avoid damaging the memory and motherboard. Please remember this! 2. If the memory causes a blue screen, crashes, restarts, or continuous beeping alarms, try the following methods one by one. If these don't resolve the issue, it's likely incompatible. Try these methods: a. Ensure the memory is properly inserted, or the gold finger may be oxidized. Use an eraser to clean the memory finger and reinsert it, or try a different slot. b. The memory slot might be dusty or oxidized. Clean it with a brush and cleaning solution (if cleaning solution is unavailable, simply brush it clean). c. The memory may be incompatible; try a different memory module. d. Reset CMOS to factory settings by removing and reinserting the motherboard battery. e. The motherboard might be incompatible with the processor; try replacing the processor. 1 x Memory Module
