48GB DDR3 ECC RDIMM Kit

This 48GB kit contains three 16GB registered DIMMs built for Dell PowerEdge 12th generation rack servers. Each module runs at 1600MHz with CL11 latency at 1.5V and uses a 2Rx4 organisation with error-correcting code.

Suits R320, R420, R520, R620, R720, R720xd, R820.

The registered ECC design makes these modules incompatible with desktop or laptop platforms that require unbuffered non-ECC memory. Buyers who need consumer SO-DIMMs or standard UDIMMs should look elsewhere.

Verify 240-pin DDR3 slots and registered support

Check your server manual for the correct population order across the three channels before installing. Confirm the system BIOS is current for the Xeon processor family installed so the kit initialises at the rated speed.

Questions about this item

Which Dell PowerEdge server models accept this 48 GB DDR3 1600 ECC RDIMM kit?

The kit is designed for PowerEdge R320, R420, R420xr, R520, R620, R720, R720xd, R820 and R920 12th-generation rack servers.

Will these registered ECC modules work with older non-ECC unbuffered DIMMs already installed in the server?

No — registered ECC RDIMMs cannot be mixed with non-ECC unbuffered memory; the system requires all slots to use registered ECC modules.

How can I confirm the 48 GB kit is running at DDR3 1600 with ECC active after installation?

Check the BIOS memory information or the OS memory report; both should show 48 GB total, 1600 MT/s speed and ECC enabled.
