Speed DDR5 4800 (PC5 38400)

Rank 1Rx8

  • 128 GB DDR5 ECC registered memory for server stability
  • 4800 MT/s CL40 timing with 1.10 V efficiency
  • Eight 16 GB modules populate eight channels
  • SK Hynix ICs on 288-pin RDIMM form factor
  • 1Rx8 organisation with 40-39-39-77 latency profile

Server-grade DDR5 capacity

This 128GB kit uses eight 16GB registered DDR5 modules rated at 4800MT/s with CL40 latency. It targets servers and workstations that require ECC error correction and registered signalling for stable operation under sustained load. The 1.1V operating voltage keeps power draw in line with standard DDR5 server specifications.

Registered design and Hynix ICs

Each module is a 288-pin RDIMM built with SK Hynix ICs on a 12-layer PCB and no heat spreader. The registered buffer reduces electrical load on the memory controller, allowing larger populations per channel. ECC circuitry detects and corrects single-bit errors, protecting data integrity in mission-critical workloads.

Upgrade from smaller DDR5 RDIMM kits

The kit replaces lower-capacity registered DDR5 sets when the platform supports eight slots and 128GB total. It is not suited for desktop boards that accept only unbuffered memory. The jump is worthwhile when the application demands maximum registered capacity per channel and the motherboard qualifies 4800MT/s registered modules.

Questions about this item

What does the DDR5 4800 (PC5 38400) rating mean for actual throughput?

The kit runs at 4800 MT/s with a PC5 38400 designation, so peak transfer rate is 38400 MB/s per module when the platform operates at the rated speed.

What physical clearance is required for these 288-pin RDIMMs?

Each stick is a standard-height 288-pin DDR5 RDIMM without a heat spreader, so it fits any server or workstation board with full-size DDR5 RDIMM slots and no tall cooler overhang.

How are the eight 16 GB modules installed, and what step is often missed?

Populate all eight slots in the order the motherboard manual specifies for 1Rx8 registered DIMMs, then enable ECC in BIOS; skipping the ECC enable step leaves error correction inactive.
