Samsung 16GB DDR32Rx4 PC3L-12800R Memory

The Samsung 16GB DDR3 2Rx4 PC3L-12800R is a type of memory module typically used in servers and workstations. Here's a breakdown of the key details:

Key Specifications:

1. Capacity: 16GB

   • The module has a capacity of 16GB of RAM.

2. Type: DDR3 (Double Data Rate 3)

   • DDR3 is an older generation of RAM, widely used in systems before DDR4 became mainstream.

3. Rank: 2Rx4

   • 2R indicates the memory is dual-ranked, meaning it has two sets of chips that can be accessed independently to improve performance.
   • x4 refers to the data width of the DRAM chips. In this case, each chip transfers data 4 bits at a time, as opposed to the more common x8 or x16 configurations in consumer memory.

4. Speed: PC3L-12800

   • The PC3L part indicates that this is a low-voltage DDR3 memory, which operates at 1.35V instead of the standard 1.5V.
   • 12800 refers to the peak data transfer rate of 12,800 MB/s or DDR3-1600. This is the speed at which the memory can read or write data.

5. Form Factor: RDIMM (Registered DIMM)

   • R indicates that the memory is registered, which means it has an additional register between the memory controller and the DRAM chips to stabilize signal integrity. This is a feature commonly used in server memory to improve scalability and reliability.

6. Compatibility: Typically used in servers or workstations, as the RDIMM configuration (registered and with ECC) is designed for enterprise-grade reliability, especially in multi-processor setups.

7. Error Correction: ECC (Error Correcting Code)

   • The module supports ECC, which helps detect and correct minor errors in memory, offering additional stability for critical applications like databases, virtualized environments, and server applications.

Use Case:

• The Samsung 16GB DDR3-1600 RDIMM module is primarily used in servers and workstations, especially those requiring error correction for data integrity and running on low-voltage to save power.
• It's commonly deployed in enterprise environments for running demanding applications where data integrity and uptime are critical.

Compatibility Considerations:

• This memory would be compatible with systems that support DDR3 RAM, RDIMM form factor, and ECC support.
• Ensure the motherboard and processor support DDR3, RDIMM, and the ECC functionality for full compatibility and performance.

If you're upgrading or replacing memory, always verify the maximum supported RAM, speed, and form factor for your specific server or workstation model.
