  • 96 GB total capacity from six 16 GB modules for high-density server workloads
  • DDR5-4800 speed with CL40 latency delivers rated bandwidth for the platform
  • Registered ECC architecture corrects single-bit errors and supports full-slot population
  • 1 V operation matches the motherboard's memory-controller specification exactly
  • 288-pin RDIMM form factor fits the Supermicro H14SST-G memory slots precisely

Exact-match DDR5 upgrade for Supermicro H14SST-G

This 96GB kit delivers six 16GB DDR5 4800 RDIMMs built to the motherboard's registered ECC specification. Each module runs at 1.10V with CL40 timing and 1Rx8 organization so the memory controller recognizes full capacity at rated speed without manual tuning.

Thermals noise and power in normal use

Operating at the standard DDR5 voltage of 1.10V keeps power draw low across all six slots. The registered architecture buffers address and command signals, reducing electrical load on the memory controller during sustained workloads. No heat spreaders are fitted, relying on chassis airflow for cooling.

Replaces partial or mismatched populations

The kit upgrades systems running fewer than six modules or mixed-rank DIMMs that force downclocking. Full population with matched 1Rx8 registered ECC restores maximum bandwidth and error correction across every channel. Buyers who need a different total capacity or a UDIMM form factor should verify their board's supported configurations first.

Questions about this item

How do I install this 288-pin RDIMM kit in the Supermicro H14SST-G, and which step do people often get wrong?

Power down the server, open the chassis, and insert each 16 GB module into the slots listed in the motherboard manual following the exact population order; the step most often missed is seating the registered DIMM until both ejector clips click, confirming the 1.1 V signal path is fully engaged.

What maintenance or replacement will this ECC registered memory need over its service life?

No scheduled maintenance is required; the modules carry a lifetime replacement warranty, so any DIMM that develops correctable or uncorrectable errors is swapped at no cost rather than repaired.

What limit appears first when this 96 GB kit runs sustained workloads at DDR5-4800?

The registered buffer and 1Rx8 organisation keep the memory controller load low, so the first bottleneck is usually the CPU memory-controller throughput or thermal envelope, not the DRAM itself.
