512 GB quad-channel DDR4 LRDIMM kit

This kit provides 512 GB of DDR4 2933 ECC load-reduced memory in four 128 GB modules. It is built for servers and workstations that require registered LRDIMM modules with 4Rx4 organisation. The quad-channel configuration allows maximum bandwidth on platforms that support four memory channels per processor. Desktop and laptop systems cannot use these modules.

Load-reduced design and ECC

The load-reduced architecture reduces electrical load on the memory bus so that higher-capacity modules can run at 2933 MHz without signal degradation. ECC detects and corrects single-bit errors, protecting data integrity in critical workloads. Each module operates at the standard 1.2 V DDR4 voltage and carries a CAS latency of CL21. No heat spreaders are fitted, so airflow in the chassis must be sufficient for bare modules.

Verify platform support for DDR4 LRDIMM

Confirm that your motherboard and processor officially support DDR4 2933 LRDIMM modules in a 4Rx4 quad-rank configuration. Check the system manual for approved memory population rules, maximum capacity per slot and channel, and any BIOS version requirements. Ensure the board has four available 288-pin DIMM slots wired for quad-channel operation before ordering.

商品問答

How do I replace a failed module in the 4x128GB kit?

Each module is a 288-pin DDR4 LRDIMM; remove the faulty stick and insert a matching 128GB 4Rx4 PC4-23400L unit in the same slot, following the server's channel guidelines.

What limits sustained throughput on these 2933 MHz LRDIMMs?

The CL21 latency at 1.20V and the quad-rank 4Rx4 organisation set the practical bandwidth ceiling during continuous workloads.

How much heat and power do four 128GB LRDIMMs generate running all day?

The kit operates at the standard 1.2V DDR4 voltage with no heat spreaders, so thermal output and power draw follow the platform's memory-subsystem design for load-reduced modules.
