OWC 128GB DDR3 ECC RDIMM Kit

This OWC kit supplies 128 GB of DDR3-1600 ECC registered memory in four 32 GB modules. It is built for Supermicro SuperServer 1017GR and 1017R systems that require 240-pin RDIMMs running at 1.5 V with CL11 timing.

Suited for 1017GR and 1017R servers

The modules suit administrators upgrading or repairing those specific Supermicro platforms. They will not work in standard desktop boards, consumer laptops, or any system that only accepts unbuffered non-ECC DIMMs.

Simple DIMM installation

Install by powering down the server, opening the chassis, and seating each 240-pin module into the correct memory slots until the latches click. The most common issue is mixing these registered DIMMs with unbuffered memory, which prevents the system from posting.

Questions about this item

What server model must I already have for this 128GB DDR3-1600 ECC RDIMM kit to work?

The kit is validated for Supermicro SuperServer 1017GR and 1017R series systems that accept 240-pin DDR3 registered ECC memory.

Can I keep my existing unbuffered DDR3 modules and add these 4Rx4 registered DIMMs alongside them?

No, registered ECC modules cannot be mixed with unbuffered memory; all slots must use registered ECC DIMMs of the same type.

How do I confirm the 128GB kit is running at the correct 1600MHz CL11 1.5V settings after installation?

Check the BIOS memory information or use a tool such as dmidecode to verify each 32GB module reports DDR3-1600, CL11, 1.5V, and registered ECC operation.
