Product Description
The "64GB 2Rx4 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:
Core Specifications
-
Capacity & Architecture:
- 64GB total capacity with a 2Rank x4 organization (2Rx4), utilizing 16Gb or 24Gb DDR4 dies 15. This configuration balances density and signal integrity for multi-channel systems.
- Supports ECC (Error-Correcting Code) for mission-critical environments, though ECC availability may vary by manufacturer 220.
-
Performance Parameters:
- Speed: DDR4-3200 (PC4-25600) with 3200 MT/s data rate, delivering 25.6GB/s peak bandwidth per DIMM 12.
- Latency: CAS-22-22-22 (CL22-tRCD-tRP), optimized for stability in server workloads rather than ultra-low latency 18.
- Voltage: 1.2V (JEDEC standard), ensuring energy efficiency and compatibility with modern server PSUs 210.
-
Form Factor:
- 288-pin RDIMM (Registered DIMM) with a full-height, full-length (FHFL) design, compatible with standard 2U/1U rack servers 214.
