  • Total capacity8 GB
  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • ECC protection prevents data corruption in critical workloads
  • Registered design stabilises signal integrity on Supermicro H11SSL-i
  • 3200 MHz DDR4 speed matches EPYC platform specs
  • 2 V operation reduces server power draw
  • 1Rx8 single-rank layout simplifies memory population

Compatible DDR4 3200 ECC RDIMM

This 8 GB registered module runs at DDR4 3200 with CL22 latency and 1.20 V. It targets IT professionals upgrading Supermicro H11SSL-i platforms that require ECC RDIMM memory for AMD EPYC server workloads.

Verify RDIMM slot availability and population rules

Confirm the motherboard has a free 288-pin DDR4 RDIMM slot and check the system manual for supported rank configurations and maximum module capacity per channel. The module is single-rank 1Rx8 and uses major OEM chips from Samsung, Micron or Hynix.

Single-module kit simplifies incremental upgrades

The package contains one 8 GB stick, allowing precise capacity scaling without purchasing matched pairs. No heat spreader is included, so airflow in dense server chassis remains unobstructed. DDR5 modules are not compatible with this DDR4 platform.

Questions about this item

Does the module ship alone or in a kit with cables or brackets?

The package contains one 8 GB DDR4 3200 ECC RDIMM module and nothing else; no cables, brackets or additional parts are included.

Should I pick the 1Rx8 CL22 stick or a different rank and latency?

This part is a single 1Rx8 module rated CL22 at 3200 MT/s; choose it when your Supermicro H11SSL-i requires a registered DIMM with those exact timings.

Will the rated 3200 MT/s speed run at that frequency on an EPYC platform?

The module is specified at DDR4 3200 (PC4-25600) with CL22 latency; the actual operating speed depends on the motherboard memory controller and BIOS configuration.
