Server Memory

Dolgix Registered DDR4 and DDR5 SDRAM DIMMs are high-speed, low-power memory modules designed for servers, workstations, and enterprise computing. DDR4 operates at 1.2V with data transfer rates up to PC4-25600, supports ECC for error detection and correction, and features fly-by topology, on-die termination, and selectable burst lengths for reliable performance. DDR5, the next-generation memory, operates at 1.1V with higher data rates starting from PC5-38400, on-die ECC, dual 32/40-bit subchannels per module, longer burst lengths (BL16), and Decision Feedback Equalization (DFE) for enhanced signal integrity. Both memory types are suitable for mission-critical systems, with DDR5 providing superior speed, efficiency, and reliability for modern computing workloads including AI, ML, and data-intensive applications.
