• Form Factor: 240-Pin RDIMM (Registered DIMM)
• Rank & Organization: Dual Rank (2Rx4) – x4-based DRAM chips for full 72-bit ECC interface
• Error Correction: ECC Registered (essential error detection and correction for server stability and data integrity in demanding environments)
• CAS Latency: CL9 (timings typically 9-10 or similar, as indicated by -09-10-E1-D2 suffix)
• Voltage: 1.5V (standard DDR3; compatible with systems supporting 1.5V; some close Samsung variants are low-voltage PC3L)
• Part Number / Labeling: Samsung M393B5170FH0-CH9 (or equivalent EH1/FH0 series); clearly labeled as PC3-10600R-09-10-E1-D2 (the -D2 suffix denotes a specific revision/qualification)
