64GB DDR4-2933 registered RDIMM for server workloads, CL21 latency at 1.20V
This 64GB DDR4 module runs at 2933 MT/s with a CAS latency of CL21 and a voltage of 1.20V. It uses a 288-pin RDIMM form factor designed for registered memory channels. The module is new and intended for server platforms that support DDR4 registered DIMMs.
The registered buffer reduces electrical load on the memory controller, allowing larger populations of DIMMs per channel without signal degradation. This makes the module suitable for configurations that require high total capacity across many slots. Systems that require unbuffered UDIMMs cannot use this part.
At the rated 1.20V the module maintains its 2933 MT/s data rate during sustained workloads without exceeding standard DDR4 voltage limits. The registered architecture helps preserve signal integrity when all channels are fully populated and running continuously.

The module runs at DDR4 2933 (PC4 23400), so each stick can move data at the rated transfer rate when the platform operates at that speed.
The registered buffer places a register between the DRAM and the memory controller, reducing electrical load and allowing larger capacities per channel.
Yes, it uses the 288-pin DDR4 RDIMM form factor and requires a motherboard slot keyed for registered DDR4 memory.
