Server memory upgrade kit

This OWC kit supplies 32GB of DDR3 1600 ECC registered memory across four 8GB RDIMMs. It targets administrators maintaining Supermicro H8DGG, H8QG6, H8QGI, H8SGL or X9DA7 platforms that require registered error-correcting modules. The 240-pin DIMMs operate at 1.5V with CL11 latency and a 1Rx4 organisation. Buyers running standard desktop boards cannot use this memory.

Replaces Supermicro MEMDR380LSL04ER16

The kit directly substitutes the Supermicro part number MEMDR380LSL04ER16, letting you extend the service life of existing infrastructure or populate a new build at lower cost. The upgrade is worthwhile when your workloads demand ECC integrity and registered signalling, and when the platform explicitly lists these motherboard series in its qualified-vendor list. Systems that accept only unbuffered DIMMs will not benefit.

Simple DIMM installation

Installation follows standard 240-pin DIMM seating: align the notch, press evenly until the latches click, then verify population rules in the board manual. Common issues include mixing these registered modules with unbuffered memory, exceeding the per-channel rank limit, or populating slots in an unsupported order. No heat spreaders are fitted, so airflow across the modules must be adequate.

Questions about this item

Does the 240-pin DDR3 RDIMM fit a Supermicro X9DA7 motherboard?

Yes, the 240-pin DDR3 1600 CL11 1.5V ECC Registered RDIMM is listed as compatible with the Supermicro X9DA7 series.

How are the four 8 GB modules installed, and what step is often missed?

Install all four modules in the correct channel slots for quad-channel operation; the step often missed is enabling the ECC Registered profile in the BIOS after installation.

When should the 1Rx4 ECC Registered RDIMM be replaced?

Replace the module if the system logs uncorrectable ECC errors or fails memory diagnostics during POST.
