Server-grade DDR4 ECC RDIMM

This 16GB registered DDR4 module runs at 2133 MHz with CL15 latency and 1.20V operation. It uses a 2Rx4 organisation and major-brand chips on a 288-pin DIMM. The part is built for server and workstation platforms that require error-correcting registered memory.

Registered DIMM platform constraints

Registered DIMMs only work in motherboards with a registered-memory memory controller; consumer desktop boards will not post with them. The module operates at the standard DDR4 2133 data rate, so the system bus must support that speed. Mixing registered and unbuffered modules is not supported.

2Rx4 rank configuration decides fit

The dual-rank 2Rx4 layout determines whether the memory controller can address the full 16GB capacity within its rank-per-channel limit. Systems capped at single-rank modules per channel cannot use this DIMM. Verify the platform's qualified-vendor list before ordering.

Questions sur cet article

Should I choose the 16 GB module or a different capacity?

This listing is for a single 16 GB DDR4 2133 CL15 ECC RDIMM. Select this module when your server needs exactly 16 GB in one slot or when you are filling multiple slots to reach a higher total.

What does the 2133 MHz rating mean for actual throughput in my server?

The module runs at 2133 MT/s, delivering up to 17 000 MB/s of peak bandwidth per stick, provided your platform’s memory controller supports DDR4-2133.

Is the 288-pin DDR4 RDIMM interface compatible with my Dell system?

Yes — the 288-pin registered DIMM matches the Dell part numbers 1R8CR, 370-ABUK, 370-ABXI, 370-ACMX, A7910488, A7946645, JMC1P, RDWTP, SNP1R8CRC/16G and SNP2133D4R15/16G.
