32 GB DDR4-2933 ECC Registered Module
This 32 GB DDR4-2933 registered DIMM adds error-correcting capacity to compatible servers and workstations. The dual-rank organisation and CL21 latency suit memory-heavy workloads such as virtualisation and database caching. It installs in standard 288-pin DDR4 slots that support registered modules.
PC4-23400 Interface Limits
The DDR4-2933 interface tops out at the PC4-23400 data rate, so total bandwidth is fixed by the memory controller and populated channel count. Registered buffering adds one clock cycle of address/command delay, which the platform must account for in timing configuration. Mixed-rank or mixed-speed populations will force the system to run at the lowest common speed.
Pre-Installation Checks
Verify that your motherboard or server platform lists DDR4-2933 registered ECC support in its qualified vendor list. Confirm the number of available 288-pin slots and the maximum capacity per channel before ordering. Ensure the BIOS is updated to a version that recognises dual-rank 32 GB modules at the rated speed.

Questions about this item
Should I choose the 32 GB dual-rank module or a single-rank alternative?
This module is a 32 GB dual-rank DDR4-2933 stick; dual rank can improve throughput on supported server platforms compared with single-rank modules of the same capacity.
What does the DDR4-2933 rating deliver in an actual server?
The module runs at 2933 MT/s with CL21 latency, providing up to 23400 MB/s theoretical bandwidth per stick when the platform supports that speed.
Does the 288-pin registered ECC interface limit the usable speed or capacity?
The 288-pin registered DDR4 interface with ECC is standard for server boards; the module operates at its rated 2933 MT/s when the motherboard and CPU memory controller support that frequency.
