370-BBHY Dell 256GB DDR5 4800MHz PC5-38400 1rx8 ECC CL40 SDRAM 288-Pin RDIMM Memory

Dell 370-BBHY Memory Overview

The Dell 370-BBHY 256GB DDR5 4800MHz PC5-38400 1Rx8 ECC Registered 1.1v CL40 SDRAM 288-Pin RDIMM for Server Memory Module represents a high-density, high-performance memory option engineered for stability and reliability in mission-critical server environments. This category focuses on RDIMM (Registered DIMM) modules that combine ECC (Error Correcting Code) capabilities with the DDR5 generation's improved throughput and power efficiency.

Key Technical

The Dell 370-BBHY module operates as a DDR5 SDRAM RDIMM that runs at an effective data rate of 4800MT/s, denoted as 4800MHz in consumer parlance, and specified as PC5-38400 to reflect the theoretical peak transfer rate measured in MB/s. Its operating voltage at 1.1 volts aligns with the DDR5 JEDEC standard and contributes to lower power consumption per bit compared to previous DDR4 modules. The CL40 CAS latency value represents the number of clock cycles between a column address strobe command and the availability of data; while higher in numeric terms than some DDR4 modules, the DDR5 architecture and doubled transfer rate mean that absolute latency in nanoseconds remains competitive for server workloads. The 1Rx8 organization indicates a single rank with x8 DRAM chips, which affects channel loading and interleaving behavior on multi-channel server memory controllers, often influencing achievable memory interleaving and bandwidth utilization.

Form Factor

The 288-pin DDR5 RDIMM form factor is the industry-standard physical specification for server memory modules in modern platforms. Mechanical compatibility with the host server is a baseline requirement; system board designs account for keying, notch placement, and retention clips consistent with JEDEC DDR5 definitions. Many Dell server lines and compatible OEM platforms list supported memory parts in their hardware compatibility lists, and the Dell 370-BBHY is intended to appear within those validated configurations to guarantee post-deployment reliability.

Latency

Although DDR5 modules often show CAS latency figures with higher numerical values compared to older DDR4 parts, the higher clock rate commonly results in similar or better absolute latencies measured in nanoseconds. For workloads sensitive to memory access latency, such as certain transactional systems or tightly-coupled HPC kernels, the net effect depends on the balance between raw bandwidth needs and latency sensitivity. Systems-level optimization, such as leveraging NUMA-aware scheduling, optimizing memory interleaving, and matching DIMM placement to recommended CPU channel populations, can mitigate perceived latency differences and maximize the effective performance of 4800MT/s RDIMMs in server contexts.

Capacity

When it comes to memory capacity, the Dell 370-BBHY DDR5 stands out with its impressive 256GB. This high-capacity module is designed to meet the demanding needs of modern applications and workloads that require significant memory resources.
