Server-grade DDR4 LRDIMM kit for enterprise

This 128 GB kit contains two 64 GB DDR4 2933 MHz modules built as ECC Load Reduced DIMMs for servers and workstations. Each stick uses a 288-pin form factor and operates at the standard 1.2 V. The quad-rank 4Rx4 organisation is intended for multi-socket platforms that support LRDIMM memory.

Quad-rank 4Rx4 organisation determines platform fit

The modules are 4Rx4 (4DRx4) Load Reduced DIMMs, a configuration that only works in systems explicitly qualified for DDR4 ECC LRDIMM memory. Desktop and laptop platforms cannot use these modules. Verify the server or workstation memory specification list before purchase to confirm 4Rx4 LRDIMM support.

Sustained throughput with ECC and reduced

Load Reduced buffering lowers the electrical load on the memory bus, allowing the quad-rank modules to maintain stable operation at 2933 MHz under continuous heavy workloads. ECC corrects single-bit errors in real time, preserving data integrity during extended compute or virtualisation tasks. The CL21 latency and 1.2 V operation keep power draw predictable while the dual-channel kit layout supports balanced bandwidth across populated channels.

Klausimai apie šią prekę

What does the 2933 MT/s rating mean for real-world throughput in a server?

At DDR4 2933 the memory bus runs at 2933 MT/s, so each module transfers data at that rate when the platform operates it at the rated speed.

How does the PC4-23400 designation relate to the module's bandwidth?

PC4-23400 is the peak transfer rate label that corresponds to DDR4 2933; the platform will cap throughput at that level when the memory runs at its rated speed.

What physical slot and clearance do these 288-pin LRDIMMs need?

They require standard DDR4 DIMM sockets with 288 pins and enough vertical clearance for the module height; the load-reduced design does not change the slot keying.
