Server Memory Kit for Enterprise Workloads

This 384GB kit contains twelve 32GB DDR4 RDIMM modules rated at 2933 MT/s with CL21 latency. ECC and registered buffering protect data integrity in multi-socket servers and high-density virtualization hosts. The 1.20V operating voltage matches standard DDR4 server specifications.

DDR4 2933 Bandwidth and Platform Limits

Peak throughput is capped by the PC4-23400 interface, so workloads that scale beyond this bandwidth will not benefit from faster modules unless the platform also supports higher speeds. Registered signalling adds one cycle of command latency, which is normal for loaded server channels but reduces raw throughput compared to unbuffered DIMMs at the same clock. Mixing ranks or voltages outside the 1.20V 2Rx4 specification can prevent the system from posting.

288-Pin RDIMM Build and Daily Handling

Modules ship without heat spreaders, relying on chassis airflow for cooling in dense 1U or blade enclosures. The 288-pin gold-edge connectors are keyed for DDR4 server slots only; they will not seat in desktop UDIMM or DDR5 sockets. Each stick carries a lifetime replacement warranty from the assembler, and the kit is validated as a matched 12-piece set to avoid single-module RMA cycles.

Questions about this item

Should I pick this 12-module 384 GB kit or a smaller capacity for my server?

This kit provides 384 GB across 12 modules of 32 GB each, so choose it when your motherboard has 12 available DDR4 RDIMM slots and you need the full capacity; otherwise select a kit with fewer modules that matches your slot count.

What does the DDR4 2933 rating deliver in an actual server?

The modules run at 2933 MT/s with CL21 latency at 1.20 V, giving registered ECC bandwidth rated at PC4-23400 for stable throughput in multi-socket workloads.

How does the 288-pin RDIMM interface limit speed or capacity?

The 288-pin DDR4 RDIMM form factor supports this 2933 MT/s speed and 2Rx4 organisation, letting each 32 GB module operate at the rated frequency while the registered buffer maintains signal integrity across all 12 slots.
