32GB DDR3L 1600 ECC LRDIMM for Servers

This 32GB DDR3L module runs at 1600 MHz with CL11 latency and 1.35V operation. It uses a 4Rx4 Load Reduced DIMM design with ECC for data integrity. The 240-pin form factor fits compatible server and workstation boards.

Direct Replacement for Samsung M386B4G70DM0 Series

The module is built as a compatible equivalent for Samsung M386B4G70DM0-YK03, M386B4G70DM0-YK04 and M386B4G70BM0-YK00 part numbers. It uses Samsung chipset components and undergoes quality assurance testing. Builders who need a second DIMM to populate a multi-channel configuration must source an additional module separately.

240-Pin Load Reduced Build for Dense Memory

The Load Reduced architecture reduces electrical load on the memory bus, allowing higher capacity per slot in supported platforms. ECC circuitry corrects single-bit errors during operation. Systems that do not support DDR3L LRDIMM or 4Rx4 organisation will not accept this module.

Questions about this item

Will the 4Rx4 load-reduced DIMM configuration require any specific motherboard slot population rules?

The 4Rx4 LRDIMM design reduces electrical load on the memory controller, allowing higher capacity per channel, but slot population rules depend on the server platform; consult your system documentation for supported configurations.

What is the maximum sustained data rate of the PC3L-12800 DDR3L 1600 interface?

The DDR3L 1600 PC3L-12800 interface provides a peak transfer rate of 12800 MB/s; sustained throughput will be lower and varies with workload, controller efficiency and CAS latency CL11 timing.

How much heat does a single 1.35V 32GB module generate under continuous 24/7 server operation?

At 1.35V the DDR3L module draws less power than standard 1.5V DDR3, reducing heat output; exact thermal load depends on system airflow, ambient temperature and memory controller activity.
