Desktop Memory Module DDR3 1600MHz Desktop 4G Memory Expansion Module Features: 2. Cost-effective: 1600MHZ frequency speed DDR3 memory transfer bandwidth and CPU data exchange faster, and good support for operating system and multi-threaded operation. Multi-tasking and large-scale games run smoothly, bringing zero-latency and super-speed experience. 3. Strict screening: Selected original granules, through the ATE test of Jintaike quality laboratory, the test accuracy reaches the digital level, ensuring that all the particles have excellent electrical performance, running performance and main AC parameters. 4. Excellent compatibility: high-quality memory material selection and advanced memory technology ensure compatibility with mainstream brands at home and abroad, support various operating systems, and ensure long-term stable operation of the system. 5. Quality Assurance: Custom-designed 8-layer black diamond PCB board, new matte solder mask, black heat-dissipating shell, anti-interference and anti-static performance; gold finger adopts high-strength electroless gold plating process, which has stronger wear resistance and oxidation resistance. And has a strong electrical conductivity, to ensure the stability of data transmission and speed, and provide 15 days no reason to return, three years of quality assurance, non-human damage package replacement, man-made damage only charge shipping and warranty costs. Specification: Capacity: 4GB Model: DDR3 color: red Applicable type: desktop Memory frequency: 1600mhz Number of pins: 240PIN Particle package: magnesium light particles Size: 13.7 * 3.3 * 0.6cm / 5.4 * 1.3 * 0.2in Weight: approx. 64g Package list: 1 * Memory Module Note: 1. The desktop computer's wide and narrow version is shipped with the arrival batch. There is no guarantee that you will purchase a wide or narrow version; the PCB color of different batches may vary. 2. Due to different batches of products, different brands of particles and different particle sizes may be used, but all of them are subjected to Jintec's strict technical test to ensure reliability: compatibility and normal use. Memory particle brand and third-party software test results cannot be As the basis for judging whether it is genuine:: DDR1 represents 1 generation of memory, DDR2 represents 2 generations of memory, DDR3 represents 3 generations of memory, and DDR4 represents 4 generations of memory; 3. "2400" in DDR4 2400 means that the memory frequency is 2400MHz, and the common memory frequency is 1333. 1600, 1866, 2133, 2400, etc. In simple terms, the higher the frequency, the faster the speed; 4. The same generation of memory, the frequency can be backward compatible, such as the frequency of DDR3 is 1333. 1600, 1866, etc., 1866 can be used on the motherboard of the 1600 or 1333, but will be used down; 5. Please refer to the relevant parameters of your PC before purchasing the memory, such as the maximum frequency that the motherboard can support, the maximum capacity supported by the single slot, etc. According to the overall hardware parameters; 6. Due to the continuous updating of our products, our product packaging will be changed with the product update. There may be some differences in different batches.
