Server-grade DDR5 ECC RDIMM

This 64GB DDR5 5600 CL46 module is a registered ECC RDIMM built for compatible Supermicro SuperServer platforms. It targets administrators upgrading workstations, NAS systems, servers or network switches that require registered memory with error correction.

Registered memory cannot mix

The DDR5 5600 PC5-44800 standard used here requires all installed DIMMs to be registered ECC; mixing registered with unbuffered or load-reduced modules will prevent the system from operating. JEDEC compliance ensures electrical and timing conformity at 1.1V, but the registered buffer adds one clock cycle of latency compared with unbuffered designs.

Verify your SuperServer model

Confirm the exact model — SSG-121E-NE316R, SSG-121E-NES24R, SSG-221E-NE324R, SYS-111C-NR or SYS-111E-FDWTR — and check the platform’s maximum supported capacity per slot and total channel population limits before ordering.

Questions about this item

Should I pick the single 64GB module or combine smaller DIMMs to reach the same capacity?

The listing is a single 64GB DDR5 5600 CL46 ECC Registered RDIMM. If your Supermicro server has free 288-pin slots you can add one module; otherwise match the existing rank and voltage configuration when mixing capacities.

What does the 5600 MT/s rating deliver inside a Supermicro SuperServer?

At 5600 MT/s the module runs at the JEDEC-standard DDR5-5600 data rate with CL46 latency and 1.1 V, giving the rated PC5-44800 bandwidth when the platform memory controller is set to that speed.

How does the DDR5 ECC Registered RDIMM interface limit real-world throughput?

The 288-pin registered DIMM presents a 64-bit data bus plus ECC at DDR5-5600, so peak throughput is capped at the PC5-44800 specification; the register adds one cycle of command latency but enables the large 64GB 2Rx4 capacity per slot.
