OWC 32GB DDR3 ECC RDIMM Kit

This 32GB kit contains four 8GB DDR3 1333 PC3-10600 CL9 registered ECC modules built for Supermicro SuperServer 5086B, 8026B and 8046B series. The 240-pin DIMMs run at 1.5V with 2Rx4 organisation and no heat spreader. They replace Supermicro part numbers MEMDR380LCL01ER13, MEMDR380LHL01ER13, MEMDR380LHL03ER13, MEMDR380LHV01ER13, MEMDR380LSL02ER13 and MEMDR380LSL06ER13.

Works in Servers Not Desktops

The registered ECC design suits workstations, servers, NAS systems and routers that require buffered memory. It will not function in standard desktop computers or any platform that only accepts unbuffered DIMMs. Builders needing unbuffered memory or a different pin count should look elsewhere.

Registered ECC Decides Compatibility

The single specification that determines fit is the registered ECC DDR3 1333 240-pin form factor. Only systems listed in the compatible SuperServer series or other platforms that explicitly support this exact module type will accept the kit.

Questions about this item

How do I know whether the 32GB kit with four 8GB modules matches my Supermicro SuperServer?

This kit is validated for Supermicro SuperServer 5086B Series, 8026B Series and 8046B Series and replaces Supermicro part numbers MEMDR380LCL01ER13, MEMDR380LHL01ER13, MEMDR380LHL03ER13, MEMDR380LHV01ER13, MEMDR380LSL02ER13 and MEMDR380LSL06ER13.

What does the 1333MHz rating mean once the modules are installed in my server?

The modules run at DDR3 1333 (PC3-10600) with CL9 latency at 1.5V, delivering the rated bandwidth when the memory controller is configured for that speed.

Will the 240-pin ECC Registered DDR3 interface work in a standard desktop motherboard?

No. These are 240-pin DDR3 ECC Registered RDIMMs designed for workstation and server platforms; they are not compatible with unbuffered desktop memory slots.
