About this item

• The new generation DDR4 memory provides a variety of models to choose from whose main frequency are upto 2400- 2666MHZ respectively, suitable for laptop memory replacement and upgrading bringing you a smooth
• HP DDR4 Memory stick has a maximum thickness of 3.4 mm and is especially suitable for ultra-thin laptops. Complies with JEDEC Standards, Features optimal memory particles, and carried out the whole process of rigorous testing, to ensure the quality of components.
• DDR4 SDRAM modules benefit from DDR4 SDRAM's use of an 8nprefetch architecture with an interface designed to transfer two data words per clock cycle at the I/O pins. A single READ or WRITE operation for the DDR4 SDRAM effectively consists of a single 8n-bit- wide, four-clock data transfer at the internal DRAM core and eight corresponding n-bitwide, one-half-clock-cycle data transfers at the I/O pins.
• DDR4 modules use two sets of differential signals: DQS_t and DQS_c to capture data and CK_t and CK_c to capture commands, addresses, and control signals. Differential clocks and data strobes ensure exceptional noise immunity for these signals and pro- vide precise crossing points to capture input signals.
• Strict selection of high quality chips: there are performance tests, electrical test, stability tests and other tests throughout each production process, to ensure chip quality.
