Server-grade DDR4 ECC kit

This 256GB kit contains four 64GB DDR4 2933 ECC registered DIMMs built for the Supermicro H12SST-PS motherboard. It targets administrators who need maximum registered capacity in a supported four-module configuration. The modules operate at 1.2V with CL21 latency and 2Rx4 organisation. They are not compatible with standard desktop platforms or unbuffered memory.

288-pin registered form factor

Each module uses the 288-pin RDIMM layout required by server chipsets and includes on-board register circuitry for signal integrity at high density. The absence of a heat spreader keeps the profile low for dense chassis layouts. Registered buffering means these DIMMs cannot be mixed with unbuffered or load-reduced memory in the same system. Installation follows standard server DIMM seating procedures.

DDR4 2933 with backward steps

The kit runs natively at 2933 MT/s (PC4-23400) and will down-clock to 2666, 2400 or 2133 MT/s when the platform demands it. Total capacity is fixed at 256GB across the four slots populated by this kit. Builders needing more memory must use a motherboard with additional DIMM slots or higher-density modules not included here.

Preguntas sobre este artículo

What DDR4 standard and speed does this kit use, and what does that cap in practice?

The kit runs at DDR4 2933 (PC4-23400) with CL21 latency and 1.2V; the motherboard's memory controller limits the actual data rate, so it will not exceed 2933 MT/s.

What physical slot and form factor do these modules need on the Supermicro H12SST-PS?

They require 288-pin DDR4 RDIMM slots; each module is a 64 GB 2Rx4 registered DIMM without a heat spreader.

How are the four modules installed, and what step do people often get wrong?

Populate all four slots following the board's channel order; the common mistake is mixing these registered ECC DIMMs with unbuffered or load-reduced memory, which the board will not accept.
