Built-in high quality chips for stable performance and high speed operation. The high memory speed of 333MHz increases the speed of your computer and brings convenience to your life. 1G capacity provides powerful performance and storage for everyday reading and writing. High-quality circuit module board, which avoids corrosion and wear, is durable and easy to carry. : Model: DDR Memory frequency: 333MHZ Memory capacity: 1G Compatible: for intel, for AMD fully compatible Compatible computer: desktop Bandwidth: PC-2700 Voltage: 2.5V Pin number: 184pin Size: Approx. 13.5*3*0.4cm/5.31*1.18*0.16inch Package List: 1 * Memory Bank Note: Memory is divided into DDR, DDR2, DDR3 models. Please refer to 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 a software test to see what memory your computer 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 Components may vary from batch to batch. The memory DDR, DDR2, and DDR3 are not common to each other, and the sockets are different. It is also impossible to force the insertion to avoid damage to the memory and the motherboard. If the memory appears: blue screen, crash, restart, alarm sounds, please follow the steps below, if not, make sure it is not compatible. 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. The memory slot is dusty or oxidized. Wash with a brush and wash water. Memory is not compatible, try another memory. CMOS does not discharge and restore the factory settings, maybe it is normal (the motherboard battery is taken down, and then installed back). The motherboard is not compatible with the CPU, try another CPU.
