Samsung M393B5173QH0-CMA 4GB

Product Description

Samsung 4GB DDR3 ECC Registered RDIMM – 1Rx4 Low Voltage  

This Samsung M393B5173QH0-CMA is a 4GB DDR3 server memory module with ECC. Featuring a 1Rx4 (Single Rank, x4) organization and 1.35V Low Voltage (LV) design, it is engineered for power efficiency and compatibility in a wide range of legacy 1U and 2U enterprise servers where specific rank and voltage requirements must be met.

Key Specifications:

• Capacity: 4GB

• Type: DDR3 SDRAM with ECC

• Speed: 1333 MHz (PC3L-10600R)

• Voltage: 1.35V Low Voltage (LV)

• Module Type: 240-pin ECC Registered DIMM (RDIMM)

• Organization: 1Rx4 (Single Rank, x4)

• Part Number: M393B5173QH0-CMA

Compatibility & Applications:

• Target Systems: Commonly used in servers like Dell PowerEdge R620/R720, HP ProLiant DL360p/380p Gen8, IBM/Lenovo System x3550 M4, and Supermicro X9 platforms that support LV-DIMMs.

• Primary Use: Maintenance, repair, or partial upgrade of legacy servers where matching the exact rank (1Rx4) and voltage (1.35V) of existing modules is critical for stability.

• ⚠ Important Note: 1Rx4 modules have specific population rules and cannot be arbitrarily mixed with other ranks (2Rx4, 1Rx8, 2Rx8). Also, 1.35V LV-DIMMs are not always backward compatible with 1.5V-only slots. Verify your server’s specifications.
