Specifications: Capacity: 8GB Module: DDR4 Suitable: For Desktop Memory Frequency: 2133mHz Colour: Red Particle Package: Magnesium Granule Size: Approx. 13.5*6.5*0.6 cm/5.31*2.56*0.24 in Package List: 1 * Memory Module Note: 1. Desktop memory wide & narrow versions vary by different arrival batches, versions not guaranteed. PCB colour may differs among batches. (Mindful Purchase) 2. Different batches use different brands and amount of granule which were all tested by Kintek Quality Lab ATE Test. Ensure reliable compatibility and regular use. Memory granule brands and third-party software test results cannot be the proof of salable products or not. 3. DDR1 for 1st Generation Memory Module, DDR2 for 2nd Generation Memory Module, DDR3 for 3rd Generation Memory Module, DDR4 for 4th Generation Memory Module 4. DDR4 2133 for memory frequency of 2133mHz. Common Frequency has 1333, 1600, 1866, 2133, 2400, etc. Higher frequency, higher speed. 5. Within the same generation, frequency can be compatible with lower frequency. For example, 1333, 1600 and 1866 for DDR3, 1866 can be used on 1600 or 1333 Motherboard with lower frequency performance. 6.
