ItemSpecifics (generated using AI, be sure to check to ensure this hardware is compatible with your system)

• Capacity: 4GB (single module)
• Memory Type: DDR3L SDRAM (Low Voltage DDR3)
• Speed: DDR3-1600 / PC3L-12800R / PC3-12800 (1600 MT/s data rate)
• Form Factor: 240-Pin RDIMM (Registered DIMM)
• Rank & Organization: Single Rank (1Rx8) – x8-based DRAM chips for 72-bit ECC interface
• Error Correction: ECC Registered (includes error detection and correction for enhanced server reliability and data integrity)
• CAS Latency: CL11 (timings typically 11-13 or similar, as indicated by -11-13-A1 suffix)
• Voltage: 1.35V (low voltage for lower power draw and heat; backward compatible with 1.5V DDR3 systems)
• Part Number / Labeling: Micron MT9KSF51272PZ-1G6E2HF (or equivalent); clearly labeled as PC3L-12800R-11-13-A1 (the -A1 suffix denotes a specific revision/timing bin)
• Compatibility: Enterprise servers and workstations (e.g., Dell PowerEdge R-series, HP ProLiant DL/ML/G8-G9, Supermicro, Lenovo/IBM, etc. supporting DDR3 ECC RDIMMs). Not compatible with consumer desktops or laptops (which use non-ECC UDIMMs only).
• Additional Notes: Genuine Micron server-grade memory; registered design reduces load on the memory controller for stable performance in multi-DIMM setups; ideal for budget server upgrades, virtualization, or homelab builds.
