OWC 16GB DDR3L ECC Registered RDIMM

This OWC module provides 16GB of DDR3L server memory running at 1600MHz with CL11 latency. It uses a 240-pin RDIMM form factor, operates at 1.35V, and features 2Rx4 registered ECC technology. The part number is 1R6T32R416GB and it matches HP part 715284001 for direct replacement.

Suits servers and workstations needing registered

This memory is built for workstations, servers, NAS systems, and routers that require registered ECC DDR3L modules. It will not work in standard desktop computers that use unbuffered non-ECC memory, and it cannot be mixed with unbuffered modules in the same system.

Registered ECC DDR3L 1600MHz 1.35V 240-pin

The registered ECC design with 2Rx4 organisation is the single specification that determines compatibility. Only systems explicitly supporting DDR3L registered ECC RDIMMs at 1.35V can use this module; all other platforms will reject it.

Questions about this item

What does the DDR3L 1600 PC3L-12800 specification mean for data rate?

The module runs at 1600 MT/s with a PC3L-12800 bandwidth rating and CL11 latency.

What physical slot and clearance does this 240-pin RDIMM require?

It needs a standard 240-pin DDR3 DIMM slot; the module has no heat spreader so it fits low-clearance server bays.

What installation step is specific to registered ECC memory?

Populate slots in the order the server manual specifies for registered DIMMs; mixing with unbuffered memory will prevent boot.
