64GB DDR4 2933MHz ECC RDIMM

This 64GB DDR4 2933MHz ECC RDIMM module is built for server and workstation systems that require registered, error-correcting memory. It operates at 1.2V with a CL21 latency and uses a 2Rx4 rank configuration. The module is a compatible replacement for the Kingston KTD-PE429/64G part.

DDR4 288-Pin DIMM interface limits

The DDR4 288-pin DIMM interface supports this module at 2933MHz (PC4-23400) with a standard 1.2V voltage. Registered DIMMs add a clock cycle for buffering, which stabilises heavy loads but prevents use in platforms that accept only unbuffered UDIMMs. Maximum capacity and speed depend on the specific motherboard and processor memory controller.

Installation and common issues

Install by aligning the 288-pin module with the DDR4 DIMM slot and pressing firmly until the retention clips lock. Common issues include mixing registered and unbuffered DIMMs, populating slots in an order the firmware does not support, or exceeding the platform's maximum rank count per channel. Verify the system's qualified vendor list before installation.

Questions about this item

Should I pick the 64GB DDR4 2933MHz ECC RDIMM or a different capacity for my server?

This listing is a single 64GB module. Choose it when your system needs one 64GB registered DIMM at 2933MHz with ECC. If your board requires a different total capacity, add or remove identical modules to match the supported configuration.

What does the 2933MHz rating deliver once the module is installed?

The module runs at DDR4 2933MHz (PC4-23400) with CL21 latency and 1.20V. In a compatible server or workstation it provides 64GB of registered ECC memory at that rated speed and timing.

Does the DDR4 288-pin RDIMM interface limit the usable speed or capacity?

The 288-pin DDR4 RDIMM form factor carries the 2933MHz signal and 64GB capacity. Actual operating speed is capped by the platform memory controller and the maximum frequency it supports for registered ECC DIMMs.
