Based on the product code **M3E73XPD-R**, this is a high-performance memory module manufactured by **Micron Technology**. Specifically, it belongs to their enterprise-grade DRAM lineup. --- ### Technical Specifications Breakdown The following table breaks down the electronic characteristics and specifications of this specific part: | Feature | Specification | | :--- | :--- | | **Component Type** | DDR5 SDRAM Memory Module | | **Module Form Factor** | RDIMM (Registered DIMM) | | **Capacity** | 32 GB | | **Data Rate** | 4800 MT/s (PC5-4800) | | **Error Correction** | ECC (Error Correction Code) | | **Voltage** | 1.1V (VDD/VDDQ) | | **Pin Count** | 288-Pin | | **CAS Latency** | CL40 | | **Rank Configuration** | 1Rx4 (Single Rank, x4 Organization) | --- ### Key Electronic Components The **M3E73XPD-R** is not just a collection of RAM chips; it is a complex circuit board designed for server stability. Here are the primary electronic sub-components: #### 1. DRAM Integrated Circuits (ICs) These are the actual storage cells. In a **1Rx4** configuration, the module uses high-density chips where each chip handles 4 bits of data. These are built using Micron’s advanced D1z or D1α process nodes, which offer lower power consumption and higher thermal efficiency. #### 2. Power Management IC (PMIC) Unlike older DDR4 modules that relied on the motherboard to regulate voltage, the DDR5 **M3E73XPD-R** features an onboard PMIC. - **Function:** Converts the 12V input from the system to the 1.1V required by the DRAM. - **Benefit:** Reduces noise, improves power integrity, and allows for better granular power management. #### 3. RCD (Registering Clock Driver) As an **RDIMM**, this module includes an RCD chip. - **Function:** It acts as a buffer between the memory controller and the DRAM chips. - **Benefit:** It buffers the command and address signals, reducing the electrical load on the CPU's memory controller, which allows the system to support more memory modules simultaneously without losing signal integrity. #### 4. SPD Hub & Thermal Sensors - **SPD (Serial Presence Detect):** An EEPROM that stores the module's timing and configuration data so the BIOS can recognize it. - **Thermal Sensors:** Integrated sensors monitor the temperature of the module in real-time, allowing the server to adjust fan speeds or throttle performance to prevent overheating. --- ### Usage Environment This part is strictly intended for **Enterprise Servers** and **High-Performance Computing (HPC)** environments. Due to the "Registered" nature (RDIMM), it is **not compatible** with standard consumer desktop motherboards, which typically require Unbuffered (UDIMM) memory.
