OWC 128GB DDR3 ECC RDIMM Kit

This kit provides 128GB of DDR3 1333 ECC registered memory across four 32GB modules. It is built for Supermicro SuperServer 5086B, 8026B and 8046B systems that require 240-pin PC3-10600 CL9 RDIMMs at 1.5V. The modules are JEDEC compliant and intended for server or workstation environments.

Suits servers needing registered ECC memory.

These modules only work in platforms that support 4Rx4 registered ECC DDR3. They will not function in standard desktop motherboards, consumer laptops or any system requiring unbuffered non-ECC memory. Buyers who need unbuffered DIMMs or a different voltage should look elsewhere.

128GB total capacity for multi-socket workloads

Four 32GB RDIMMs fill four slots and deliver 128GB of registered ECC capacity for virtualisation, database or compute tasks. Headroom ends when the platform reaches its maximum supported DIMM count or total memory limit. Systems needing more than 128GB must use higher-density modules or additional memory channels.

Highlights

Questions about this item

What motherboard form factor and CPU socket does this 240-pin DDR3 1333 ECC RDIMM kit require?

This kit is validated for Supermicro SuperServer 5086B, 8026B and 8046B systems; the motherboard must accept 240-pin DDR3 1333 registered ECC modules.

Can I keep my existing 8GB unbuffered DDR3 DIMMs and add these four 32GB registered modules?

No. Registered ECC RDIMMs cannot be mixed with unbuffered memory; all slots must use registered ECC modules.

How do I verify the 128GB kit is running at PC3-10600 CL9 1.5V after installation?

Enter the server BIOS or use a hardware inventory tool; it should report 1333 MT/s, CL9 timings, 1.5 V and registered ECC status for each 32GB module.
