16GB DDR3L ECC RDIMM kit

This kit supplies 16GB of DDR3L ECC registered memory in a matched pair of 8GB modules. It is built for workstations, servers and NAS systems that require registered DIMMs with error correction. Standard desktop boards cannot use registered memory, so this kit will not work in consumer platforms.

240-pin 1.35V CL11 specification

The modules run at 1600MHz (PC3L-12800) with CL11 latency at 1.35V. Registered buffering and ECC are integrated on each stick, and the 1Rx4 organisation matches the density expected by the listed Supermicro X9 series motherboards. No heat spreaders are fitted, keeping the profile low for dense server chassis.

Supermicro X9 series compatibility

The kit replaces Supermicro part numbers MEMDR380LHL07ER16, MEMDR380LSL10ER16, MEMDR380LSL14ER16 and MEMDR380LSV04ER16 across X9DBU, X9DR3, X9DR7, X9DRD and X9DRE boards. It cannot be mixed with unbuffered DIMMs, so buyers who need to combine memory types should look elsewhere.

Questions about this item

Will the 1Rx4 ECC registered modules require any firmware updates or reconfiguration after installation?

No firmware updates are needed; the 1Rx4 registered DIMMs initialise automatically on supported Supermicro X9 series boards.

What thermal limit appears first when the 1.35 V DDR3L kit runs continuously at 1600 MHz?

The 1.35 V operating voltage keeps power draw low, so the modules stay within JEDEC thermal limits without active cooling.

How much heat and noise do the two 8 GB RDIMMs add when the server runs all day?

Without heat spreaders the sticks rely on chassis airflow; they add negligible heat and produce no audible noise.
