Server memory module

This OWC 32GB DDR3L 1600 PC3L-12800 CL11 4Rx4 ECC RDIMM module is a 240-pin registered DIMM built for Supermicro SuperServer 4047R, 4048B, 5017GR, 5017R and 5027R series systems. It runs at 1.35V and meets JEDEC and RoHS specifications for warranty-safe upgrades.

Workstation and server upgrades only

The module suits administrators extending the life of compatible Supermicro servers or building new ones with registered ECC memory. It will not work in standard desktop computers and cannot be mixed with unbuffered DIMMs, so buyers needing consumer memory should look elsewhere.

Registered ECC with 4Rx4 organisation

The single 32GB stick uses 4Rx4 registered ECC DDR3L at 1600MHz CL11, a configuration required by the listed Supermicro platforms. Systems that demand unbuffered memory or a different rank layout will not accept this module.

Questions about this item

How much power does the 1.35V DDR3L module draw when the server runs continuously?

Operating at 1.35V instead of the standard 1.5V reduces power draw and heat output during sustained workloads.

What must the Supermicro motherboard already provide for this 240-pin registered ECC DIMM to function?

The board must support DDR3L registered ECC memory with 4Rx4 organisation and accept 240-pin RDIMMs.

Can this 32GB stick sit alongside older DDR3 RDIMMs already installed in a SuperServer 5017R?

It cannot be mixed with unbuffered modules; all slots must use registered ECC DIMMs of matching voltage and speed.
