Capacity and role

This 32 GB DDR4 module is built for servers that need error-correcting memory without registered buffering. It suits administrators expanding capacity in platforms that accept unbuffered ECC DIMMs at standard voltage.

Sustained operation

The dual-rank 2Rx8 organisation runs at 3200 MHz with CL22 latency and 1.20 V, delivering steady throughput for long-running workloads. Intel XMP 2.0 support allows the BIOS to apply the rated profile automatically during extended sessions.

Build and connectors

A bare 288-pin DIMM without a heat spreader keeps the profile low for dense chassis layouts. The unbuffered ECC design plugs directly into standard DDR4 server slots, simplifying installation and daily maintenance.

Questions about this item

How much heat does the 3200 MHz CL22 module add when it runs continuously at 1.20 V?

The module operates at the standard DDR4 voltage of 1.20 V without a heat spreader, so thermal output stays within normal DDR4 limits for a dual-rank 32 GB DIMM under sustained load.

What motherboard slot and firmware feature must my system provide for this 288-pin DIMM to work?

The module needs a DDR4 288-pin DIMM slot and the platform must enable ECC in the BIOS; XMP 2.0 support is optional and only required if you want the rated 3200 MHz profile applied automatically.

Will this ECC unbuffered DDR4 DIMM work alongside older DDR4 modules that lack ECC?

No — mixing ECC and non-ECC modules on the same channel disables error correction and can prevent the system from booting; all populated slots should use ECC unbuffered DDR4 at the same voltage.
