Dell PowerEdge 13th Gen Server Memory

This 256GB kit contains four 64GB DDR4 LRDIMM modules built for Dell PowerEdge 13th generation rack servers. It targets administrators upgrading R430, R530, R630, R730, R730xd, R830 or R930 platforms that require ECC load-reduced memory. The modules are not compatible with desktop or laptop systems that only accept non-ECC unbuffered DIMMs.

Capacity and Headroom

Four quad-rank 64GB modules deliver 256GB total capacity at DDR4 2400 speed with CL17 latency. The load-reduced design reduces electrical load on the memory controller, allowing dense population across all channels. Mixing with registered ECC DIMMs is not supported, and the system will clock down to the slowest installed module speed.

Thermals and Power

Each module operates at 1.20V without a heat spreader, relying on server chassis airflow for cooling. Load-reduced architecture lowers per-pin current draw compared to standard registered DIMMs at equivalent density. Power consumption scales with active ranks and data rate; sustained heavy workloads increase thermal output proportionally.

Highlights

  • 256 GB total capacity across four 64 GB modules
  • DDR4 2400 MHz speed rated at PC4-19200
  • ECC Load Reduced DIMM for data integrity
  • 20 V operating voltage for efficient power use
  • Compatible with Dell PowerEdge 13th Gen rack servers

Questions about this item

Will these 4Rx4 LRDIMM modules work alongside the existing 2Rx4 RDIMMs in my PowerEdge R730?

No — ECC Load Reduced and ECC Registered modules cannot be mixed. All installed modules must share the same ECC type, so the R730 must use only LRDIMMs or only RDIMMs.

How can I confirm the kit is running at DDR4 2400 CL17 after installation?

Check the system BIOS or iDRAC memory inventory — it will report each module as 64 GB, 2400 MT/s, CL17, 1.20 V, 4Rx4 LRDIMM.

Does the package include only the four 64 GB modules, or are any cables or brackets supplied?

The box contains four 288-pin DDR4 LRDIMM modules and nothing else; no cables, brackets or additional hardware are included.
