64 GB DDR5 ECC RDIMM kit

This 64 GB kit contains four 16 GB DDR5 4800 modules built for registered ECC server platforms. It targets IT teams upgrading Dell PowerEdge R6615 rack servers or compatible enterprise motherboards. Each module runs at 1.10 V and uses a 288-pin RDIMM form factor. The registered design buffers address and command signals for large-capacity stability.

Registered ECC with 1Rx8 organisation

The single-rank 1Rx8 layout and on-die ECC provide error correction without unbuffered timing penalties. CL40 latency at DDR5 4800 (PC5-38400) matches the JEDEC base specification for this speed grade. Modules are validated against the Dell PowerEdge R6615 qualified-vendor list using major OEM DRAM from Samsung, Micron or Hynix. No heat spreader is fitted, relying on server chassis airflow.

1.10 V operation in dense server chassis

At the standard 1.10 V DDR5 voltage the kit draws minimal power per module, helping thermal headroom in 1U rack enclosures. Registered buffering reduces electrical load on the memory controller, lowering system-level power under sustained workloads. Passive cooling is sufficient when installed in Dell-validated configurations with directed airflow. Acoustic impact is negligible compared to chassis fans.

Questions about this item

What does 4800 MT/s mean once the kit is installed in a Dell PowerEdge R6615?

The modules will run at DDR5 4800 speed, delivering PC5 38400 bandwidth with CL40 latency at the rated 1.10 V.

What does the 288-pin RDIMM interface cap in practice?

The registered DDR5 RDIMM form factor fits standard server DIMM slots and is limited to the 4800 MT/s data rate and CL40 timing specified for this kit.

What physical space does a 4 x 16 GB kit need inside the chassis?

Four 288-pin RDIMM modules occupy four adjacent DIMM slots; no heat spreaders are fitted, so standard server airflow clears them.
