512 GB DDR4 ECC RDIMM kit for servers

This 512 GB kit contains eight 64 GB registered DIMMs built for DDR4 servers and workstations that require ECC memory. It is not compatible with standard desktop or laptop platforms.

DDR4 2933 MT/s registered interface limits

The modules run at 2933 MT/s with CL21 latency at the standard 1.2 V DDR4 voltage. Registered buffering and ECC add latency overhead that desktop memory controllers do not expect, so the kit will only function in platforms validated for DDR4 RDIMM populations.

Major-brand chips on 288-pin dual-rank modules

Each stick uses major-brand DRAM in a 2Rx4 organisation across the 288-pin edge connector. The registered design places a buffer between the memory controller and the DRAM, which stabilises heavy multi-module loads but requires motherboard slots wired for registered DIMMs.

Questions about this item

Should I choose the 512GB kit with eight 64GB modules or a smaller capacity for my server?

The 512GB kit provides eight 64GB modules for maximum supported capacity in compatible DDR4 servers and workstations.

What does the 2933 MHz speed mean for actual server workloads?

DDR4 2933 (PC4-23400) delivers high bandwidth for virtualization, databases and multi-threaded applications with CL21 latency at 1.2V.

Is the 288-pin RDIMM interface limited to specific server platforms?

The 288-pin DDR4 RDIMM form factor with ECC and registered signalling works only in DDR4 server and workstation platforms that support 2Rx4 modules.
