64 GB DDR5 ECC RDIMM kit

This 64 GB kit contains four 16 GB DDR5 4800 registered DIMMs built for HP Z8 G5 and Z8 Fury G5 workstations. Each module runs at 1.1 V with a CAS latency of CL40. The kit targets professionals who need error-correcting memory for stable operation in supported HP platforms.

Registered ECC with 1Rx8 organisation

The modules use a 1Rx8 layout and registered buffering to maintain signal integrity across all four slots. ECC capability detects and corrects single-bit errors during heavy workloads. Compatibility is limited to the HP Z8 G5 and Z8 Fury G5 systems listed by the supplier.

Low-voltage DDR5 operation

Running at 1.1 V, the DDR5 modules draw less power than previous-generation server memory while delivering 4800 MT/s throughput. The absence of heat spreaders relies on chassis airflow for cooling. Acoustic impact is negligible because the DIMMs have no moving parts.

Questions about this item

What does the 4800 MT/s speed mean once the kit is installed in a Z8 G5 or Fury G5 workstation?

The modules run at the standard DDR5 4800 data rate, delivering PC5-38400 bandwidth with CL40 latency for registered ECC workloads.

How does the DDR5 RDIMM interface and registered design affect usable capacity and speed?

The 288-pin registered DIMM presents a 1Rx8 load per module, allowing the memory controller to address all 64 GB at the rated 4800 MT/s with ECC active.

What physical clearance and slot layout does the four-module kit require in the workstation?

Each 288-pin RDIMM fits a standard DDR5 RDIMM slot; the kit occupies four slots and has no heat spreader, so it clears typical CPU coolers.
