64GB DDR4 2933 ECC Load Reduced DIMM

This 64GB DDR4 module runs at 2933 MT/s with CL21 timings and is built for servers that require error-correcting code memory. The quad-rank, load-reduced design targets platforms needing high capacity per slot.

288-pin registered form factor and quad-rank density

The 288-pin DDR4 interface fits standard server DIMM sockets while the load-reduced buffer lowers electrical load on the memory controller. Quad-rank organisation delivers 64GB in a single module, reducing the number of slots required for large memory configurations.

Replaces lower-capacity or non-ECC DDR4 modules

Upgrading to this module adds 64GB of registered ECC capacity per slot, which is worthwhile when the platform supports load-reduced DIMMs and the workload demands maximum density with error correction. It is not suited for consumer desktop boards that lack registered memory support.

Questions about this item

What does the DDR4 2933 (PC4 23400) rating mean for real-world throughput?

The module runs at 2933 MT/s, giving a peak transfer rate of 23400 MB/s per channel when the memory controller operates at the rated speed.

Will this 288-pin DDR4 module fit my server's DIMM slots?

It uses the standard 288-pin DDR4 form factor, so it fits any server DIMM slot keyed for DDR4 registered memory.

How do I install this quad-rank load-reduced DIMM, and what step is often missed?

Power down the server, open the chassis, align the notch with the slot key, press firmly until both retention clips lock, then verify in BIOS that all 64 GB are detected at 2933 MT/s with ECC enabled.
