What is the speed and capacity of Lenovo 03KL457?

The 03KL457 provides 32GB capacity at DDR5-4800 MT/s (PC5-38400), with 1Rx4 configuration on a 288-pin RDIMM. This enables peak bandwidth for multi-core CPUs in ThinkSystem servers, outperforming DDR4-3200 by fetching larger data chunks via 16-burst length.

Is the 03KL457 compatible with Lenovo ThinkSystem servers?

Yes, designed for ThinkSystem platforms with Intel Xeon Scalable or AMD EPYC processors featuring DDR5 controllers. Actual speed may adjust to 4400 MT/s based on DIMM population per channel for signal integrity.

What benefits does 1Rx4 provide over other ranks?

1Rx4 offers efficient single-rank access with 10x4 DRAM organization, balancing performance and compatibility. Dual sub-channels allow concurrent operations, reducing latency in high-I/O workloads like virtualization.

Does it support ECC for enterprise use?

Yes, full ECC support corrects single-bit errors and detects multi-bit errors, critical for data centers. Combined with Registered buffer, it ensures stability in 24/7 operations.

How does DDR5 architecture improve efficiency?

DDR5 doubles prefetch and burst length to 16, uses two 32-bit sub-channels per DIMM for better command queuing, and operates at lower 1.1V, enhancing bandwidth utilization in analytics and databases.

What workloads benefit most from this module?

Ideal for memory-intensive tasks like in-memory analytics, large databases, and virtualization where 32GB density per slot maximizes total system memory without expansion limits.

Product overview

The Lenovo 03KL457 is a high-performance 32GB DDR5 RDIMM module designed for demanding data center and enterprise server environments. Operating at 4800 MT/s (PC5-38400), it features ECC error correction, 1Rx4 architecture with 10x4 organization, and 288-pin Registered DIMM form factor at 1.1V. This module unlocks DDR5 benefits including doubled burst length (16 vs DDR4's 8), dual 32-bit sub-channels for improved command efficiency, and higher bandwidth for CPU-intensive workloads. Ideal for Lenovo ThinkSystem servers with Intel Xeon Scalable or AMD EPYC processors, it supports virtualization, in-memory databases, analytics, and multi-threaded applications. The 32GB density enables high total memory configurations in slot-limited systems, reducing bottlenecks in east-west traffic and accelerating data processing across rising core counts. Engineered for stability under continuous operation, it maintains signal integrity even in densely populated channels, with potential downclocking to 4400 MT/s for optimal performance.
