32 GB DDR4 2933 ECC RDIMM for Supermicro Servers

This 32 GB DDR4 2933 module is built for Supermicro platforms that require registered ECC memory. It delivers 2933 MT/s at CL21 with a 1.20 V operating voltage. The dual-rank 2Rx4 organisation suits multi-socket servers and virtualisation hosts that need high capacity per slot.

DDR4 2933 registered DIMM limits

The DDR4 2933 interface tops out at PC4-23400 bandwidth, so throughput is fixed by the memory controller rather than the module. Registered buffering adds one clock cycle of latency but allows larger memory populations per channel. Systems that only support unbuffered UDIMMs or lower speeds cannot use this module.

Hynix 288-pin RDIMM build and daily handling

The module uses Hynix chips on a 288-pin RDIMM PCB with standard 1.2 V power. The registered design means the module presents a lighter electrical load to the memory controller, which helps stability in fully populated servers. Installers must align the key notch with the server slot; forcing the module risks bent pins and damaged sockets.

Questions about this item

Should I pick the 32 GB 2Rx4 module or look for a different capacity?

This module is a single 32 GB stick with a 2Rx4 organisation. Choose it when your server needs a 32 GB registered DIMM that fits a 288-pin DDR4 slot and the platform supports dual-rank registered memory.

What does the 2933 MHz rating deliver once installed?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency at 1.20 V, giving the bandwidth and error-correction your platform expects from a certified registered DIMM.

How does the DDR4 RDIMM interface limit performance?

The 288-pin registered DDR4 interface caps the module at the 2933 MHz data rate and CL21 timing specified; the registered buffer adds one cycle of address/command delay but enables the larger capacities servers require.
