  • Four 8 GB modules provide 32 GB total capacity
  • Standard 1.2 V DDR4 voltage reduces power draw

Server ECC memory kit

This 32 GB kit contains four 8 GB DDR4 ECC UDIMM modules rated at 2400 MHz with CL17 latency. Each module is a 2Rx8 dual-rank DIMM operating at the standard 1.2 V. The kit is designed for servers and workstations that require error-correcting unbuffered memory.

288-pin DDR4 platform fit

The modules use the 288-pin DDR4 DIMM form factor and are compatible only with systems that support DDR4 ECC unbuffered memory. They are not compatible with standard desktop or laptop computers. Builders must verify the motherboard or server manual for supported speeds, ranks and population rules before installation.

Standard voltage thermals

At 1.2 V the modules run at the standard DDR4 voltage, which helps keep power draw and heat output within normal limits for ECC UDIMM operation. No extra cooling beyond typical server airflow is required. The dual-rank organisation provides density without increasing voltage or thermal load.

Questions about this item

How does the CL17 latency affect sustained throughput?

CL17 sets the minimum cycle delay for each column access; lower latency would reduce wait states during long compute runs but the modules operate at the rated 2400 MHz speed.

What thermal or power behaviour should be expected when all four modules run continuously?

Each module runs at the standard 1.2 V DDR4 voltage, so total power draw scales with four dual-rank DIMMs; typical server airflow handles the resulting heat without extra cooling.

Which motherboard feature must already be present for this kit to function?

The board must provide DDR4 ECC UDIMM slots with 288-pin connectors and support dual-rank x8 modules at 2400 MHz.
