Server ECC RDIMM

This OWC DDR3 1333 module provides 8 GB of ECC registered memory for Supermicro SuperServer 6036T, 6046T, 7046A, 7046GT and 7046T systems. It uses a 240-pin form factor with 2Rx4 organisation and CL9 latency. The part is designed for server and workstation platforms that require registered ECC DIMMs and will not operate in standard desktop computers or alongside unbuffered modules.

Thermals and power

Operating at 1.5 V, the module follows standard DDR3 voltage levels for registered server memory. No heat spreader is fitted, so cooling depends on the server chassis airflow across the DIMM slots. Power draw remains within JEDEC limits for PC3-10600 registered parts during normal multi-user workloads.

Sustained load behaviour

Under continuous demand the registered buffer helps maintain signal integrity across fully populated channels. ECC corrects single-bit errors on the fly, preventing data corruption during long compute or virtualisation tasks. The module is validated as a direct replacement for Supermicro part numbers MEMDR380LCL01ER13, MEMDR380LHL01ER13, MEMDR380LHL03ER13, MEMDR380LHV01ER13, MEMDR380LSL02ER13 and MEMDR380LSL06ER13.

Questions about this item

How do I install this 240-pin DDR3 RDIMM in a Supermicro SuperServer 6036T, and what step is often missed?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until the retention clips click, then verify in BIOS that the 8 GB module is detected at 1333 MHz with ECC enabled.

What maintenance or replacement will this registered ECC module need over its service life?

No routine maintenance is required; if a correctable error count rises or the module fails, replace it with another 8 GB DDR3 1333 CL9 2Rx4 1.5 V registered DIMM to keep matched ranks across the channel.

What limit appears first when this 1.5 V DDR3 RDIMM runs sustained workloads in a 7046GT?

The 1.5 V operating voltage and CL9 latency at 1333 MHz set the thermal and timing envelope; prolonged heavy use will hit the module's rated voltage and timing limits before any other constraint.
