What this module is

RIMLANCE RRD23400D4C64 is a 64GB DDR4 2933 registered ECC RDIMM built for server and workstation platforms. It runs at PC4-23400 with CL21 latency, 2Rx4 organisation and a 1.2V operating voltage across 288 pins. The module uses major-brand DRAM chips and is validated for stable operation in multi-socket environments.

Who should buy this and who should not

This suits administrators expanding memory in DDR4 servers that require registered ECC modules at 2933 MT/s. It does not suit builders of consumer desktops or laptops that accept only unbuffered non-ECC memory, nor systems limited to lower DDR4 speeds or different form factors.

The specification that decides fit

The module is a 288-pin DDR4 registered ECC RDIMM rated at 2933 MT/s with CL21 timing; the platform must explicitly support registered ECC DDR4 at this speed and pin count for the module to function.

Questions about this item

Should I choose the single 64GB module or look for a kit of smaller modules?

This listing is a single 64GB RDIMM; select it when your server has a free 288-pin slot and you want maximum capacity per slot, otherwise buy multiple identical modules to fill the required channels.

What does the 2933MHz rating actually deliver inside a server?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency, providing the peak bandwidth your platform negotiates; registered buffering and ECC keep data integrity stable under sustained loads.

How does the 288-pin DDR4 interface limit the usable speed?

The 288-pin DDR4 slot caps operation at the module's rated 2933MHz; the registered design adds one clock cycle of buffering, so the memory controller must support DDR4 RDIMM at that frequency.
