  • 16 GB DDR3L 1333 MHz module increases server capacity
  • ECC RDIMM with 4Rx4 organisation detects and corrects data errors
  • Registered signal buffering improves stability in multi-DIMM configurations
  • Low-voltage 1.35 V operation reduces power draw and heat
  • Tested as compatible replacement for Samsung M393B2K70CM0-YH9

Server Memory Upgrade

This 16GB DDR3L module replaces Samsung M393B2K70CM0-YH9 in servers and workstations. It runs at 1333MHz with CL9 latency and registered ECC for data integrity. The low-voltage design suits systems qualified for 1.35V DDR3L DIMMs.

Thermals and Power Draw

Operating at 1.35V reduces power consumption compared to standard 1.5V DDR3. Registered buffering adds slight electrical load on the memory controller. Passive cooling relies on chassis airflow; no active cooler is included.

Build Quality and Connectors

The 240-pin DIMM uses Samsung chipset components tested to PC3L-10600 specifications. The 4Rx4 organisation increases density but requires a memory controller that supports quad-rank modules. Verify platform qualification before installation.

Perguntas sobre este artigo

How do I install this 240-pin DDR3L RDIMM and what step is often missed?

Power off the server, open the chassis, align the notch on the 240-pin DDR3L module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 16GB ECC registered module is detected at 1333MHz and 1.35V.

What maintenance or replacement will this 4Rx4 ECC RDIMM need over time?

No scheduled maintenance is required; if a correctable error count rises or the module fails POST, replace the 16GB DDR3L stick with an identical 4Rx4 registered part to keep ECC protection and rank balance.

What limit appears first when this 1.35V DDR3L module runs under sustained load?

The 1333MHz data rate and CL9 latency set the throughput ceiling; the memory controller will throttle before the 1.35V low-voltage chips reach a thermal limit.
