Understanding LRDIMM Technology

Load Reduced DIMMs represent an advancement over standard Registered DIMMs (RDIMMs):

How LRDIMMs Differ from RDIMMs

LRDIMMs use a memory buffer (MB) chip instead of a register to further reduce the electrical load on the memory controller. This allows for:

• Higher memory capacities per channel
• Better signal integrity in fully-populated configurations
• Improved performance at high capacities

When to Choose LRDIMMs

LRDIMMs are particularly beneficial in:

• Maximum memory capacity configurations
• High-density server deployments
• Applications requiring large memory pools (in-memory databases, virtualization)

Applications and Use Cases

The massive 256GB capacity makes this module ideal for:

In-Memory Databases

SAP HANA, Oracle Database In-Memory, and other memory-optimized databases benefit from the large, fast memory pool.

Virtualization Environments

VMware ESXi, Microsoft Hyper-V, and other hypervisors can support more VMs with such high-capacity modules.

High Performance Computing

Scientific computing, financial modeling, and AI/ML workloads that process large datasets in memory.

Cloud Infrastructure

Cloud service providers can achieve higher VM density per host with these high-capacity modules.

Performance Considerations

When deploying these high-capacity modules:

Memory Bandwidth

At 3200 MT/s, these modules provide excellent bandwidth for data-intensive workloads.

Latency Characteristics

While higher capacity modules typically have slightly higher latency, the CL22 rating maintains good responsiveness.

Power Efficiency

DDR4's 1.2V operation combined with LRDIMM efficiency provides better performance-per-watt than previous generations.

Comparing New vs. Refurbished Memory

Advantages of choosing this refurbished module:

Cost Savings

Typically 30-60% less expensive than new modules while offering similar performance.

Environmental Benefits

Extends the lifecycle of premium components, reducing e-waste.

Availability

Often available when new modules may be on long lead times.
