The part number **0C1-R1** (often formatted as **0C1 R1** or associated with specific prefixes like **SR0C1**) typically refers to a specific hardware revision or an Intel Core processor stepping code (S-Spec). In the context of electronic components and semiconductors, here is the breakdown of what this part usually represents: --- ## 1. Technical Identification Most commonly, **0C1** (specifically SR0C1) identifies an **Intel Core i7-3820 Processor**. The "R1" designation generally refers to the **stepping** or **revision** of the silicon. ### Component Specifications: Intel i7-3820 (SR0C1) | Feature | Specification | | :--- | :--- | | **Product Collection** | 2nd Generation Intel Core i7 Processors | | **Socket Type** | FCLGA2011 | | **Cores / Threads** | 4 Cores / 8 Threads | | **Base Frequency** | 3.60 GHz | | **Max Turbo Frequency** | 3.80 GHz | | **Cache** | 10 MB Intel Smart Cache | | **Bus Speed** | 0 GT/s | | **TDP** | 130 W | --- ## 2. The "R1" Revision Meaning In electronics manufacturing, the suffix **R1** indicates the first major revision of the part after the initial release. * **Silicon Stepping:** It tells engineers and repair technicians which version of the internal circuitry is being used. * **Compatibility:** R1 revisions may resolve "errata" (hardware bugs) found in the initial "R0" or prototype versions. * **Microcode:** BIOS/UEFI firmware requires specific microcode updates to recognize and properly manage the R1 stepping of a CPU. --- ## 3. Alternative Contexts If this part is not a CPU, it may appear in different electronic systems as follows: ### A. Surface Mount Resistors/Capacitors In some schematic diagrams, `0C1` or `R1` are shorthand labels: * **R1:** Usually denotes **Resistor #1** on a Printed Circuit Board (PCB). * **0C1:** Can sometimes represent a specific capacitor on "Channel 0." ### B. Proprietary Industrial Parts Certain manufacturers of industrial controllers or automotive ECUs use `0C1-R1` as a sub-assembly code for a specific power rail or a logic board revision. --- ### Summary Checklist for Identification 1. **Look for Branding:** If the part has an "Intel" logo, it is a Sandy Bridge-E processor. 2. **Physical Form:** Is it a large square chip (CPU) or a tiny rectangular component (SMD)? 3. **Circuit Location:** If printed on a green board next to a component, it is a reference designator, not the part number itself.
