The Samsung M393B5273CH0-YH9 (Dell P/N SNP9J5WFC/4G) is an enterprise-grade 4GB DDR3-1333 (PC3L-10600R) Registered ECC DIMM designed for reliable server and workstation performance. Operating at a low-voltage 1.35V specification, it delivers energy efficiency and reduced thermal dissipation while remaining backward-compatible with 1.5V systems. Ideal for legacy enterprise environments, it provides multi-bit error detection and single-bit correction for 24/7 mission-critical operations.
The M393B5273CH0-YH9 is architected using Samsung C-die 2Gb DDR3 SDRAM components arranged in a dual-rank x8 (2Rx8) configuration, utilizing 16 individual 256Mx8 DRAM packages alongside an integrated Register Clock Driver (RCD). The RCD buffers command, address, and clock signals, significantly lowering electrical loading on the host memory controller to maintain signal integrity across multiple DIMMs per channel. A 72-bit bus structure provides 64 data bits and 8 dedicated parity bits for system-level Error-Correcting Code (ECC).
Decoding the Samsung part number reveals M393 (DDR3 RDIMM form factor), B (DDR3 SDRAM), 52 (2Gb density), 73 (x8 width, 2 ranks), C (third-generation C-die), H0 (design revision), Y (low-voltage 1.35V DDR3L), and H9 (DDR3-1333 speed binning with 9-9-9 CAS timing). The cross-referenced Dell part number SNP9J5WFC/4G designates OEM qualification and firmware compliance for Dell PowerEdge and Precision enterprise platforms.
Always verify against your server's qualified vendor list (QVL).
Yes. DDR3L modules are dual-voltage capable and will automatically adjust to 1.5V if inserted into legacy server boards or mixed with standard 1.5V DDR3 modules.
No. Enterprise systems do not permit mixing RDIMMs, UDIMMs, or LRDIMMs within the same server; all installed modules must use the same buffering technology.
SNP9J5WFC/4G is Dell's customer kit part number certifying this Samsung RDIMM for full firmware compatibility and performance validation across supported Dell PowerEdge and Precision systems.
