Server DDR3 ECC LRDIMM

This 32 GB Crucial module uses 240-pin DDR3 SDRAM rated at 1600L with CL11 latency and 1.35 V operation. It is built for enterprise servers that require registered load-reduced memory with error correction.

Sustained throughput

Load-reduced buffering lowers electrical load on the memory controller, allowing quad-channel kits to maintain bandwidth during long compute jobs. ECC protects data integrity across extended workloads without the throughput penalty of unbuffered alternatives.

Thermal and power profile

Operating at 1.35 V reduces power draw compared to standard 1.5 V DDR3, helping chassis airflow stay manageable in dense racks. The bare PCB design omits a heat spreader, relying on directed server airflow for cooling.

Questions about this item

How much heat does the 1.35V DDR3 1600L Load Reduced module produce during continuous operation?

At 1.35 volts the module draws less power than standard 1.5V DDR3, reducing heat output in 24/7 server workloads.

What motherboard slot and channel configuration are required for this 240-pin quad-channel kit?

The kit needs four 240-pin DDR3 slots wired for quad-channel operation and a chipset that supports Load Reduced ECC memory.

Will the CL11 4Rx4 Load Reduced modules work in a system that currently runs single-rank registered DDR3?

Mixing 4Rx4 Load Reduced modules with single-rank registered DIMMs is not supported; the memory controller must address all ranks identically.
