  • SpeedDDR5 4800 (PC5 38400)
  • ECCYes
  • Buffered/RegisteredRegistered
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • Voltage1.10V
  • 192GB total capacity across six 32GB modules
  • DDR5 4800 speed with CL40 latency for server workloads
  • ECC registered RDIMM ensures data integrity under load
  • 1V operation reduces power draw in dense configurations
  • Validated for SuperMicro SYS-221HE series SuperServer platforms

System-Specific DDR5 4800 RDIMM Kit

This 192GB kit contains six 32GB registered DDR5 modules rated at 4800MT/s with CL40 latency and 1.1V operation. ECC and 1Rx4 organisation provide error correction and signal integrity for the SuperMicro SYS-221HE platform. The 288-pin RDIMM form factor fits the server motherboard memory slots directly.

Compatibility and Limits

The kit is validated for SuperMicro IOT SuperServer SYS-221HE-FTNR, SYS-221HE-FTNRD and SYS-221HE-TNR systems. It is not suited for platforms that require unbuffered DIMMs, non-ECC memory or a different pin count. Builders needing lower capacity or consumer-form-factor modules should look at other products.

Deciding Specification

The registered DDR5 4800 ECC RDIMM 288-pin interface is the single specification that determines whether this kit will install and function in the target SuperMicro server.

Questions sur cet article

How do I install the 6x32GB DDR5 4800 CL40 ECC RDIMM kit in my SuperMicro SYS-221HE, and which step do people often miss?

Power down the server, open the chassis, and seat each 288-pin module firmly until the retention clips click. The step most often missed is populating all six slots in the exact order the motherboard manual specifies for 1Rx4 registered DIMMs.

What maintenance or replacement will the 192GB DDR5 4800 ECC RDIMM kit need over its service life?

No scheduled maintenance is required for the modules themselves. Keep the server air filters clean so the 1.10V DIMMs stay within thermal limits, and run periodic memory diagnostics to catch any correctable ECC errors before they become uncorrectable.

What limit appears first when the 1Rx4 DDR5 4800 CL40 registered kit runs sustained workloads on the SYS-221HE?

The memory controller’s maximum supported speed of 4800 MT/s is the first ceiling; the modules are already rated at that speed, so sustained throughput cannot exceed the PC5-38400 bandwidth without overclocking, which registered ECC DIMMs do not support.
