DDR5-4800MHz Performance Characteristics

Operating at 4800MHz, the Supermicro MEM-DR564L-HL01-ER48 memory module delivers a substantial increase in bandwidth compared to DDR4-based solutions. The PC5-38400 data rate enables faster data transfers between system memory and processors, reducing latency in memory-bound applications such as in-memory databases, real-time analytics, and high-performance computing simulations. This enhanced throughput allows servers to process more transactions simultaneously, improving overall system efficiency.

The increased frequency of DDR5 memory also supports modern CPU architectures that feature higher core counts and wider memory buses. By matching processor capabilities with adequate memory bandwidth, enterprise systems can avoid bottlenecks that limit application scalability and responsiveness.

Latency Optimization and CL40 Timing

Latency remains a critical factor in enterprise memory performance, particularly for transactional workloads and latency-sensitive applications. The CL40 timing specification of this DDR5 module is optimized to balance high-frequency operation with stable access times. While higher clock speeds typically introduce latency trade-offs, DDR5 architecture compensates through improved prefetch mechanisms and enhanced memory bank structures.

For enterprise deployments, consistent latency behavior is often more important than raw timing numbers. The Supermicro MEM-DR564L-HL01-ER48 memory is engineered to deliver predictable latency under sustained workloads, ensuring stable application response times even during peak utilization.

Error Correction and Data Integrity

Error Correcting Code memory plays a vital role in maintaining data accuracy within enterprise systems. The ECC functionality embedded in this DDR5 RDIMM module detects and corrects single-bit memory errors while identifying multi-bit faults. This capability significantly reduces the risk of data corruption, system crashes, and silent data errors that can compromise business operations.

In environments where uptime and data integrity are paramount, such as financial services, healthcare platforms, and enterprise resource planning systems, ECC memory is not optional but essential. The Supermicro MEM-DR564L-HL01-ER48 module supports these requirements by integrating advanced ECC logic aligned with modern server processor memory controllers.

Registered DIMM Signal Stability

The registered DIMM design incorporates a register chip that buffers address and command signals, reducing electrical load on the memory controller. This architecture enables servers to populate more memory slots without signal degradation, supporting higher total memory capacities per system. As enterprises consolidate workloads onto fewer physical servers, this scalability becomes increasingly valuable.

Signal stability is particularly important in multi-socket server configurations, where memory channels span greater physical distances across the motherboard. The RDIMM architecture of this Supermicro module ensures consistent signal timing, improving system reliability and simplifying large-scale memory deployments.

2Rx4 Dual-Rank Configuration Benefits

The 2Rx4 dual-rank configuration of the Supermicro MEM-DR564L-HL01-ER48 memory module enhances performance by allowing the memory controller to interleave access across multiple ranks. This interleaving improves effective bandwidth and reduces access contention, particularly in multi-threaded workloads that generate parallel memory requests.

Dual-rank memory modules often provide better performance scaling than single-rank alternatives in enterprise environments. By optimizing rank utilization, this DDR5 RDIMM supports balanced memory throughput across diverse application profiles.

Power Efficiency and Thermal Management

DDR5 memory introduces significant improvements in power efficiency compared to earlier generations. With onboard power management integrated into the module, voltage regulation becomes more precise, reducing overall power consumption and improving signal integrity.
