Product Description
The "16GB 2Rx8 DDR4-3200 CAS-22-22-22 RDIMM Memory Module (CTO&BTO)" is a high-performance registered DIMM designed for enterprise servers and data centers, offering flexible customization through Configure-to-Order (CTO) and Build-to-Order (BTO) options. Below is a detailed analysis of its specifications, compatibility, performance, and application scenarios, incorporating insights from the latest industry trends and technical data:
Core Specifications
-
Capacity & Architecture:
- 16GB total capacity with a 2Rank x8 (2Rx8) organization, utilizing 16Gb DDR4 dies . This configuration balances density and signal integrity for multi-channel systems, supporting up to 24 DIMMs in 2U servers.
- ECC (Error-Correcting Code) is standard for mission-critical environments, though non-ECC variants may be available via CTO for cost-sensitive deployments 1213.
-
Performance Parameters:
- Speed: DDR4-3200 (PC4-25600) with 3200 MT/s data rate, delivering 25.6GB/s peak bandwidth per DIMM .
- Latency: CAS-22-22-22 (CL22-tRCD-tRP), optimized for stability in server workloads rather than ultra-low latency. Despite higher CL values compared to consumer-grade RAM, the true latency in nanoseconds (13.75ns) remains competitive due to the high clock rate 56.
- Voltage: 1.2V (JEDEC standard), ensuring energy efficiency and compatibility with modern server PSUs .
-
Form Factor:
- 288-pin RDIMM (Registered DIMM) with a full-height, full-length (FHFL) design, compatible with standard 2U/1U rack servers .
