16GB DDR3 ECC RDIMM for Dell Precision R5500

This 16GB DDR3 1333 PC3-10600 CL9 registered DIMM is built for the Dell Precision R5500 workstation. It delivers 16GB of ECC registered memory in a single 240-pin module. The 1.5V 2Rx4 design targets server and workstation users who need error-correcting stability.

Registered ECC limits desktop and mixed-memory use

Registered ECC DDR3 will not work in standard desktop motherboards that require unbuffered modules. It cannot be mixed with unbuffered memory in the same system. The PC3-10600 1333MHz CL9 specification defines the speed ceiling for this upgrade path.

Single-module 240-pin design simplifies installation

The module has no heat spreader, keeping the profile low for dense server chassis. One 16GB stick fills a single slot, leaving other DIMM sockets free for further expansion. JEDEC and RoHS compliance confirms standard manufacturing quality.

Questions about this item

Should I pick this single 16GB module or combine two for 32GB in my Dell Precision R5500?

The R5500 accepts registered ECC RDIMMs; populate slots in matched pairs per Dell's memory guide to reach 32GB with two 16GB sticks.

What does the 1333 PC3-10600 rating deliver once installed in the R5500?

The module runs at 1333 MHz with CL9 latency, providing the peak bandwidth the R5500 memory controller expects for registered ECC operation.

How does the 240-pin DDR3 registered ECC interface limit what I can mix with this module?

Registered ECC RDIMMs cannot be mixed with unbuffered non-ECC DIMMs; all populated slots must use the same registered ECC type.
