8GB DDR4 2133 ECC RDIMM for servers

This 8 GB DDR4-2133 registered DIMM delivers ECC protection and a single-rank 1Rx4 layout for server and workstation platforms that require error-correcting memory. It operates at the standard 1.2 V DDR4 voltage and matches the specifications of Hynix HMA41GR7AFR4N-TF, HMA41GR7BJR4N-TF and HMA41GR7MFR4N-TF modules.

DDR4-2133 bandwidth and registered buffering

The module runs at 2133 MT/s (PC4-17000) with CL15 latency, limiting peak throughput to the DDR4-2133 ceiling. The registered buffer adds one clock cycle of address-command delay, which stabilises heavy loads but reduces raw speed compared with unbuffered DIMMs at the same data rate.

288-pin DIMM installation and compatibility checks

Insert the 288-pin DIMM into a compatible DDR4 RDIMM slot; the key notch prevents mis-orientation. The most common issue is a platform that does not support registered ECC modules or that requires a different rank configuration, so verify the system's qualified-vendor list before purchase.

Questions about this item

Should I choose the 8GB 1Rx4 module or a different capacity for my server?

This module is an 8GB DDR4 2133 ECC RDIMM with 1Rx4 organisation; select it when your platform requires a single-rank registered DIMM at this density.

What does the 2133 MHz rating deliver in an actual system?

The module runs at DDR4 2133 (PC4-17000) with CL15 latency at 1.20 V, providing standard server bandwidth and error correction for compatible platforms.

How does the DDR4 288-pin RDIMM interface limit performance?

The 288-pin registered DDR4 interface caps operation to the JEDEC 2133 MT/s data rate and requires a motherboard that supports ECC RDIMMs at 1.2 V.
