4GB DDR3L ECC Registered DIMM

This 4GB DDR3L module runs at 1600MHz with CL11 latency and 1.35V low voltage. It is built as a registered ECC DIMM using a 2Rx8 configuration with major brand chips. The 240-pin form factor fits server and workstation boards that require registered memory. It serves as a direct replacement for Dell part A6994474.

Steady throughput under continuous load

Registered buffering reduces electrical load on the memory controller, allowing stable operation during sustained workloads. ECC circuitry detects and corrects single-bit errors in real time, preventing data corruption during long compute tasks. The low-voltage DDR3L design limits heat output while maintaining the rated 1600MHz speed over extended periods.

240-pin registered build for dense servers

The 240-pin DIMM uses a registered interface that supports higher module counts per channel than unbuffered alternatives. Major brand chips are tested to stringent quality standards for dependable daily operation. Low-voltage 1.35V operation eases power budget constraints in multi-DIMM configurations. Buyers needing unbuffered UDIMMs or higher capacities per module should verify platform requirements before ordering.

Questions about this item

How much power does the 1.35V DDR3L module draw when the server runs continuously?

Operating at 1.35V, this DDR3L RDIMM consumes less power than standard 1.5V DDR3, reducing heat output during 24/7 server workloads.

What motherboard slot and chipset support are required to use this 240-pin ECC RDIMM?

You need a server or workstation motherboard with a 240-pin DDR3 DIMM slot that supports registered ECC memory and 1.35V DDR3L operation.

Will this CL11 1600MHz registered module work alongside older CL9 DDR3 DIMMs already installed?

Mixing registered ECC with unbuffered non-ECC DIMMs is not supported; all slots must use registered ECC modules of matching voltage and rank configuration.
