## Analysis of W2CE-512-R/Q Electronic Component The **W2CE-512-R/Q** is a specialized high-density memory module, typically identified as a **DDR2 SDRAM Registered DIMM**. This specific part numbering is common in industrial computing and legacy server environments. --- ### 1. Technical Specifications Below are the primary technical parameters associated with this component type: | Parameter | Specification | | :--- | :--- | | **Memory Type** | DDR2 SDRAM | | **Form Factor** | 240-Pin Registered DIMM (RDIMM) | | **Capacity** | 512 MB | | **Error Correction** | ECC (Error Correction Code) | | **Voltage** | 1.8V | | **Pin Count** | 240-Pins | | **Bus Speed** | PC2-3200 (400 MHz) or PC2-4200 (533 MHz) depending on sub-revision | --- ### 2. Core Functional Components The "R/Q" designation in the part number often refers to the internal architecture and qualification standards: * **Registered (Buffered) Interface:** This module includes a register chip (buffer) between the system memory controller and the DRAM chips. This reduces electrical load and allows for higher system stability in multi-slot configurations. * **ECC (Error Correction Code):** The module includes extra data bits (72-bit width instead of 64-bit) to detect and correct single-bit memory errors, preventing system crashes. * **DRAM ICs:** The module is populated with several individual DDR2 memory chips (usually 9 chips per side for ECC). --- ### 3. Key Identification Codes Understanding the suffix and prefix: * **W2:** Often used by specific manufacturers or distributors (like Wintec or similar industrial brands) to denote a specific product line. * **512:** Denotes the capacity (512 Megabytes). * **-R:** Indicates a **Registered** memory module. * **-Q:** Often signifies **Qualified** or **Quad-Rank** in some naming conventions, though in 512MB modules, it more likely refers to a specific RoHS compliance or component grade. --- ### 4. Common Applications Due to its registered nature and ECC support, this part is not meant for standard consumer laptops or desktops. It is used in: 1. **Legacy Servers:** Early Intel Xeon or AMD Opteron systems. 2. **Industrial Workstations:** Precision equipment requiring high stability. 3. **Network Appliances:** High-end routers or firewalls from the mid-2000s. ---
