The **M2AS1-4322-R/CE** is a specialized high-performance memory module typically manufactured by **Apacer**. It is part of their industrial-grade Server/Workstation DRAM lineup. --- ## 🛠️ Technical Specifications This part is a **32GB DDR4 3200MHz ECC Registered DIMM (RDIMM)**. Below is the detailed breakdown of its electronic characteristics: | Parameter | Specification | | :--- | :--- | | **Memory Type** | DDR4 SDRAM | | **Form Factor** | 288-pin Registered DIMM (RDIMM) | | **Capacity** | 32 GB | | **Speed** | 3200 MT/s (PC4-25600) | | **CAS Latency** | CL22 | | **Voltage** | 1.2V (Standard DDR4 Low Voltage) | | **Error Correction** | ECC (Error Correcting Code) | | **Rank** | 2Rx4 (Dual Rank) | | **Operating Temp** | 0°C ~ 85°C | --- ## 🧩 Key Components and Architecture The module consists of several critical electronic components integrated onto the PCB: ### 1. DRAM Integrated Circuits (ICs) The board features high-density memory chips (likely from manufacturers like Samsung, SK Hynix, or Micron). As a **2Rx4** module, it uses a x4 data width per chip, which allows for higher density and better advanced ECC features like "Chipkill" or "Device Tagging." ### 2. Registering Clock Driver (RCD) The "R" in RDIMM signifies that it includes a **Register**. This chip acts as a buffer between the memory controller and the DRAM ICs. * **Function:** It re-drives control and address signals, reducing the electrical load on the CPU's memory controller. This allows for higher system stability when using multiple modules. ### 3. Serial Presence Detect (SPD) EEPROM with Thermal Sensor * **SPD:** A small non-volatile memory chip that stores the module's timing, voltage, and manufacturer data so the BIOS can configure it automatically. * **Thermal Sensor:** Many industrial-grade R/CE modules include an integrated digital thermal sensor to monitor temperature and prevent overheating through thermal throttling. ### 4. Decoupling Capacitors Small SMD (Surface Mount Device) capacitors are distributed across the PCB to filter electronic noise and stabilize the 1.2V power delivery to the DRAM ICs during high-speed switching. --- ## 📑 Applications Due to the **ECC (Error Correcting Code)** and **Registered** architecture, this part is strictly for: * **Enterprise Servers:** Data centers requiring 24/7 uptime. * **Workstations:** High-end CAD, video rendering, or scientific computing. * **Networking Gear:** Industrial-grade routers or storage arrays. ---
