Capacity and configuration

This 512GB kit contains four 128GB DDR5 RDIMM modules. It is intended for servers and workstations that require registered ECC memory and can populate four DIMM slots. Systems needing non-ECC or unbuffered memory cannot use this kit.

Registered ECC RDIMM requirement

The modules are 288-pin DDR5 4800 (PC5-38400) with CL40 latency and 4Rx4 organisation. They operate at 1.10V and include on-die ECC with registered buffering. Only motherboards that support DDR5 RDIMM registered ECC memory at this speed and rank configuration will accept the kit.

Thermals and power

Modules run at 1.10V without heat spreaders, relying on chassis airflow for cooling. Registered buffering and ECC add minimal overhead to power draw. Acoustic output is determined by the server fans rather than the memory itself.

Questions sur cet article

What does DDR5 4800 CL40 mean for real-world throughput in this server board?

The modules run at 4800 MT/s with CL40 latency, so the board can move data at the DDR5 4800 rate when the memory controller trains at that speed.

How does the 288-pin RDIMM interface and registered design affect what the system can address?

The 288-pin DDR5 RDIMM format with registered buffering lets the memory controller drive four 128 GB modules at 1.1 V while maintaining signal integrity across all ranks.

What physical clearance and slot population does this 4 x 128 GB kit require?

The kit fills four 288-pin DDR5 RDIMM slots; each module has no heat spreader, so standard server DIMM spacing applies.
