1TB DDR4 3200 ECC LRDIMM kit

This 1TB server memory kit contains four 256GB DDR4 3200MHz modules rated at PC4-25600. Each module operates at 1.2V with CAS latency 22 and uses an 8Rx4 load-reduced design. It is built for enterprise servers that require registered ECC memory.

288-pin load-reduced DIMM compatibility

The 288-pin LRDIMM form factor fits server motherboards designed for DDR4 load-reduced memory. The registered buffer reduces electrical load on the memory controller, allowing higher total capacity per channel. ECC capability detects and corrects single-bit errors to protect data integrity.

Sustained throughput at 3200MHz

Under continuous workloads the kit maintains its rated 3200MHz transfer rate with stable 1.2V operation. Load-reduced architecture keeps signal quality consistent across all four modules during extended compute tasks. CAS latency 22 timing remains steady without thermal throttling.

Questions about this item

Will the CAS latency of 22 become a bottleneck during sustained heavy workloads?

The modules run at CAS 22, which is the standard timing for DDR4-3200 ECC LRDIMM and does not introduce an additional bottleneck beyond the rated speed.

How much heat and power should I expect from four 256 GB LRDIMMs running continuously?

Each module operates at 1.2 V, the standard DDR4 voltage, and the load-reduced design lowers electrical load on the memory bus, keeping thermals and power draw within typical server DIMM limits.

Does my server need to support 8Rx4 LRDIMM and 288-pin DDR4-3200 to use this kit?

Yes, the platform must accept 288-pin DDR4 LRDIMM modules at 3200 MT/s with 8Rx4 organisation and ECC for the kit to function.
