  • 512GB total capacity from sixteen 32GB modules for high-density server workloads
  • DDR5 5600 PC5-44800 speed delivers fast data throughput for demanding applications
  • ECC registered design detects and corrects errors to protect critical data integrity
  • Low 1.1V operating voltage reduces power draw in dense memory configurations
  • 2Rx8 dual-rank organisation with CL46 latency optimises bandwidth for multi-threaded tasks

Server-Scale DDR5 Capacity

This 512 GB kit delivers sixteen 32 GB registered DDR5 modules rated at 5600 MT/s with ECC. It targets enterprise servers and workstations that require maximum registered memory capacity per board. The 1.1 V operating voltage and 2Rx8 organisation suit high-density DIMM populations.

Upgrade From Lower-Capacity Registered Kits

Replacing smaller RDIMM sets with this kit fills every slot with 32 GB modules, raising total system memory without exceeding the 5600 MT/s JEDEC speed. The jump is worthwhile when workloads such as virtualisation, in-memory databases or large-scale simulation exceed the capacity of 16 GB or 8 GB registered sticks.

Build Integration For Registered DDR5 Platforms

Each module presents a 288-pin registered interface and on-die ECC, so the platform must support registered DDR5 and the full 512 GB population. The kit frees administrators from mixing module densities and avoids the complexity of populating partial channels with mismatched ranks.

Questions about this item

Will the 288-pin DDR5 RDIMMs fit my server's DIMM slots?

These are standard 288-pin DDR5 RDIMMs; they require a server platform with DDR5 RDIMM slots and cannot be used in desktop or laptop SO-DIMM sockets.

What is the correct way to seat all sixteen 32 GB modules, and which step is often missed?

Power down, open the chassis, align each module's key notch with the slot, press firmly until both ejector clips click, then verify in BIOS that all 512 GB are detected at 5600 MT/s.

How do I know when a module in this 16-piece kit needs replacing?

ECC corrects single-bit errors; if the system logs uncorrectable errors or marks a DIMM as degraded, swap that specific 32 GB RDIMM — the remaining fifteen modules continue operating.
