64GB DDR4-2933 ECC Registered module
This 64GB DDR4-2933 ECC Registered module is built for servers and workstations that require high-capacity, error-correcting memory. It operates at 2933MHz with a CAS latency of 22. The dual-rank design helps maximise density per slot. It is sold new as a single 288-pin DIMM.
Registered ECC with dual-rank organisation
The registered buffer and ECC functionality are the decisive specifications for compatibility. This module uses a registered signal to reduce electrical load on the memory controller, and ECC to detect and correct single-bit errors. Both features must be supported by the platform; consumer desktop boards typically cannot use this memory.
Fits 288-pin DDR4 slots on qualified platforms
Installation requires a 288-pin DDR4 slot on a motherboard and processor combination that explicitly supports registered ECC DIMMs and dual-rank modules at this capacity. The registered design frees the memory controller from driving heavy capacitive loads. Buyers needing unbuffered non-ECC memory or higher speeds must select a different module type.

คำถามเกี่ยวกับสินค้านี้
What does the 2933 MHz speed mean for actual throughput in a server?
The module runs at 2933 MT/s, delivering up to 23400 MB/s theoretical bandwidth per stick; real-world throughput depends on the platform's memory controller and channel population.
How does the registered DDR4 interface affect usable speed?
The registered design adds a clock cycle of buffering for signal integrity, allowing the 2933 MT/s rate to scale across large memory arrays without exceeding the DDR4 electrical limits.
Will the 288-pin dual-rank module fit my server's DIMM slots?
It uses the standard 288-pin DDR4 RDIMM form factor with dual-rank organisation, so it fits any server board that accepts registered DDR4 DIMMs of this height.
