Registered DDR4-2400 kit for servers

This kit provides 8 GB of DDR4 memory in a matched pair of 4 GB registered DIMMs. Each module carries a single 1Rx8 rank and runs at 1.20 V. It is intended for servers and workstations that require registered memory with standard-height modules.

DDR4-2400 interface limits

The DDR4-2400 standard tops out at 2400 MT/s with a PC4-19200 data rate. Registered buffering adds one clock cycle of latency, which is reflected in the CL17 timing. Systems that accept only unbuffered DIMMs or that are limited to lower DDR4 speeds cannot use this kit.

8 GB capacity and headroom

The 8 GB total fits entry-level virtualization hosts, small database instances and typical file-server workloads. Workloads that need larger in-memory datasets or many concurrent virtual machines will exceed this capacity and require higher-density modules or additional DIMM slots.

Questions about this item

Should I choose the 2×4 GB kit or look for a single 8 GB module?

The kit provides two 4 GB registered DIMMs that together give 8 GB total capacity in a dual-channel configuration.

What does DDR4-2400 CL17 actually deliver in a server?

It runs at 2400 MT/s with 17-cycle latency, yielding a peak transfer rate of 19200 MB/s per module.

How does the PC4-19200 registered interface limit performance?

The 288-pin registered DDR4 interface caps the data rate at 2400 MT/s and adds one cycle of buffering for signal integrity.
