Item Type: Memory Module Model: DDR Material: PCB Memory Frequency: 226MHZ Memory Capacity: 1GB Compatibility: Fully compatible with Intel/AMD Applicable Computer: Desktop Bandwidth: PC-2100 Voltage: 2.5V Pin Number: 184Pin Note: 1. Memory is divided into memory cards, DDR, DDR2, DDR3 models. Please check the following list to know what memory is 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 which memory your favorite computer needs. After running the software, look at the column \"Max Bandwidth\" in the option \"SPD\", 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 cannot 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 operate according to 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 insert it again, or replace the socket; b. The memory socket is dusty or oxidized. Use a brush and washing water to clean it (if you don't have washing water, just brush it down) c. The memory is not compatible, try another memory. d. CMOS is not discharged 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 Your satisfaction is our top priority. We will provide you with the best service.
