64GB DDR4-2666 ECC LRDIMM for servers

This 64GB DDR4-2666 module is built for enterprise servers that require high-density memory with error correction. It targets administrators expanding virtualization capacity or extending the service life of existing rack infrastructure.

4Rx4 Load-Reduced architecture with CL15 timing

The module uses a 4Rx4 Load-Reduced organisation running at 1.20V with a CAS latency of 15. This specific rank and buffering combination determines whether the memory controller can address the full 64GB per slot.

Fits 288-pin DDR4 slots accepting LRDIMMs

Installation requires a platform qualified for DDR4 Load-Reduced DIMMs at the PC4-21300 data rate. It frees additional DIMM slots by delivering 64GB in a single module, but it is not suitable for systems limited to standard Registered or Unbuffered DDR4.

Questions about this item

What does 2666 MT/s mean for my server's throughput?

The DDR4-2666 rating lets each module transfer data at 2666 million transfers per second, raising peak bandwidth for memory-bound workloads.

What does the PC4-21300 designation cap in practice?

PC4-21300 confirms DDR4-2666 operation with CL15 timing at 1.2 V on any 288-pin DDR4 slot that supports LRDIMM.

What slot and clearance does this 288-pin LRDIMM need?

It fits a standard 288-pin DDR4 DIMM slot; the load-reduced design uses the same keying as registered DIMMs but requires platform support for LRDIMM.
