128GB DDR3L ECC RDIMM kit

This OWC kit supplies 128GB of DDR3L memory across four 32GB registered DIMMs. It is built for workstations, servers and NAS systems that require ECC registered modules. Standard desktop computers cannot use this memory.

Compatibility check before ordering

Verify that your motherboard is a Supermicro X9DBU, X9DR3, X9DR7, X9DRD or X9DRE series board. The modules run at 1.35V and use a 240-pin DDR3L interface. They must not be mixed with unbuffered memory.

Build quality and daily implications

Each module follows JEDEC and RoHS standards without a heat spreader. The registered design adds a clock cycle for signal integrity in dense configurations. Four ranks per DIMM (4Rx4) increase electrical load on the memory controller.

Questions about this item

What comes in the box and is anything else required?

The kit includes four 32GB DDR3L 1600 CL11 1.35V ECC registered 240-pin RDIMM modules. No additional parts are needed for installation on a compatible Supermicro X9 series motherboard.

How do I decide between the available capacity options?

This part number 1R6T34R4128S is a single 128GB kit containing four 32GB modules. If your board has more slots or you need a different total, select another kit from the product range.

What does the 1600MHz CL11 rating mean once the memory is installed?

The modules run at DDR3L 1600 (PC3L-12800) with CAS latency 11 at 1.35V. The registered ECC design adds one cycle of buffering for signal integrity on supported Supermicro X9DBU, X9DR3, X9DR7, X9DRD and X9DRE boards.
