32GB DDR4 2400 ECC RDIMM

This 32GB DDR4 2400 ECC RDIMM is built for servers and workstations that require registered, error-correcting memory. It uses Samsung chips and carries Supermicro certification for qualified platforms. The module runs at 1.2V with a CAS latency of 17.

DDR4 2400 registered limits

DDR4 2400 registered DIMMs operate at 2400 MT/s with a PC4-19200 bandwidth rating. The registered buffer adds one cycle of latency, so the memory controller must support registered modules. Mixing registered and unbuffered DIMMs on the same channel is not supported by the standard.

2Rx4 dual-rank density

The 2Rx4 organisation places two ranks of x4 chips on a single 288-pin module. This density allows 32GB per slot but requires a memory controller that can address dual-rank registered DIMMs. Systems limited to single-rank modules will not recognise the full capacity.

Questions about this item

Should I choose the 32GB module or a smaller capacity for my server?

This module provides 32GB in a single 288-pin RDIMM. Select it when your board has free slots and you need maximum capacity per slot; choose a smaller module only if you must populate more channels with the same total memory.

What does the 2400 MHz rating mean once the module is installed?

The module runs at 2400 MHz with CL17 timing at 1.20 V, delivering the stated DDR4 2400 speed when the platform supports that data rate.

What does the PC4-19200 designation cap in practice?

PC4-19200 is the DDR4 2400 standard bandwidth label for this registered ECC module; actual throughput is limited by the memory controller and the 288-pin RDIMM interface.
