High-Performance Server Memory Solution

The solution supports up to 4TB memory capacity per socket using LRDIMM modules. With 8 memory channels and 2 DIMM slots per channel, a total of 16 DIMMs can be installed. Using 256GB LRDIMMs, the maximum capacity is 4TB. For RDIMM configurations, typical maximum is 2TB using 128GB modules. Actual capacity depends on CPU memory controller capabilities and platform design.

For maximum capacity, specify LRDIMM. For balanced cost and capacity, RDIMM is typically sufficient. Contact us for platform-specific capacity planning.

DDR5 introduces dual 32-bit independent channels per DIMM, compared to DDR4's single 64-bit channel. This provides several advantages: improved access efficiency with independent channel scheduling, better granularity for small transfers, and reduced latency for concurrent accesses. The two 32-bit channels can operate independently, allowing the memory controller to service two requests simultaneously if they target different channels. This architecture effectively doubles the number of independent channels available to the memory controller.

The dual-channel architecture is automatic in DDR5. Ensure your memory controller supports independent channel scheduling for optimal performance.

High-density DDR5 modules require careful thermal management due to increased power density. Recommended approaches include: heatsinks on DIMMs for modules with high power dissipation, adequate chassis airflow (typically 200-400 LFM), temperature sensors on each DIMM for monitoring, and dynamic thermal management algorithms. DDR5 includes on-chip temperature sensors that can trigger thermal throttling when junction temperatures exceed safe limits. Proper thermal design is critical for reliable operation at high data rates.

Implement comprehensive thermal monitoring and management. Contact our FAE team for thermal simulation and cooling design support.

The DDR5 memory interface components in this solution deliver exceptional power efficiency with 1.1V operation for the memory interface chips. This is 10-15% improvement in power efficiency compared to DDR4 components. The PMIC components provide dynamic power management, and the integrated temperature sensors enable thermal regulation. Overall DDR5 systems can achieve better performance per watt than DDR4 systems.

Expected 10-15% power savings over DDR4 systems. Power savings improve TCO despite higher initial component costs.
