Feature: 1. This memory module has good compatibility, stable operation, and it is not easy to blue screen, crash and fail to boot. 2. The memory module is resistant to high temperatures and has a fast heat dissipation rate, while increasing the computer memory and improving computer performance. 3. These memory modules have high‑quality memory particles and powerful performance, which can provide you with smooth running efficiency whether you are playing games or working. 4. These memory modules are inspected and strictly tested by large‑scale high‑accuracy equipment to confirm the quality of each memory stick. 5. The memory module is suitable for desktop computers with strong compatibility and high stability. Specification: Item Type: Memory ModuleModel: DDR Memory Frequency: 333HMZ Memory Capacity: 1GB Compatibility: For AMD dedicated strip Applicable Computer: Desktop Bandwidth: PC-2700 Voltage: 2.5V Pin Number: 184Pin.If the memory appears: blue screen, crash, restart, and the alarm keeps beeping, please operate one by one according to the following methods. If it fails, it is determined that it is not compatible. Try the Following Methods: 1. The memory is not inserted properly, or the gold finger is oxidized. Use an eraser to remove the memory finger and then reinsert it, or change the slot; 2. The memory slot is dusty or oxidized. Use a brush and wash water to clean it (if you don’t have wash water, just brush it down) 3. The memory is not compatible, try changing the memory. 4. The CMOS is not discharged to restore the factory settings, maybe it is normal (the motherboard battery is removed, and then put it back). 5. The motherboard is not compatible with the CPU, try changing the CPU Package List: 2 x Memory Module Note: The memory is divided into memory card, DDR, DDR2, DDR3 models. Please check the following list to know what memory has been 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 what memory your favorite computer needs. (Enter in the Baidu search bar: "CPU‑Z download", search for a CPU‑Z software, download it and unzip it), after running the software, look at the "Max Bandwidth" column of the "SPD" option, you will see "PCxx00", as follows:PC2100 is DDR 266 memoryPC2700 is DDR 333 memoryPC3200 is DDR 400 memoryPC4200 is DDR2 533 memoryPC4300 is DDR2 533 memoryPC5300 is DDR2 667 memoryPC6400 is DDR2 800 memoryPC8500 is DDR3 1066 memoryPC10700 is DDR3 1333 memoryPC12800 is DDR3 1600 memoryMemory DDR, DDR2, DDR3 are not common to each other, and the sockets are also different. Don't force the Overlord to insert it in, so as not to damage the memory and the motherboard, remember.
