High-Capacity ECC RDIMM for Servers

This 64GB DDR4 registered DIMM targets server and workstation platforms that require error-correcting memory. The single-module design suits administrators upgrading capacity in validated slots without mixing kits.

DDR4 3200 Interface Constraints

The module runs at 3200 MT/s with CL22 latency at the standard 1.20V. Registered buffering and ECC add command-cycle overhead that the memory controller must support; consumer boards without RDIMM qualification will not post with this module installed.

64GB 2Rx4 Density Decides Fit

The 2Rx4 organization across a 288-pin DIMM delivers 64GB in one slot. Systems limited to lower per-slot density or to unbuffered UDIMM topology cannot use this part; verify the platform’s qualified-vendor list for the Samsung M393A8G40AB2-CWE or M393A8G40BB4-CWE equivalents before purchase.

Questions sur cet article

Should I choose this single 64GB module or multiple smaller modules for my server?

This module provides 64GB in one 288-pin DIMM, leaving other slots free for future expansion if your board has more than one slot per channel.

What does the 3200MHz rating mean for actual throughput in my system?

At DDR4 3200 (PC4-25600) the peak transfer rate reaches 25600 MB/s, though real-world bandwidth depends on your CPU memory controller and channel population.

How does the ECC RDIMM interface affect compatibility and performance limits?

The registered ECC design adds a register that buffers address and command signals, allowing higher capacities per channel while the memory controller must support registered DIMMs.
