ECC Unbuffered UDIMM Kit

This kit provides 64 GB of DDR5 memory across two 32 GB modules. It targets workstations, servers and NAS systems that require error-correcting code for data integrity. The modules are unbuffered and operate at the standard 1.1 V JEDEC voltage. Compatibility covers desktop, all-in-one and server platforms that accept 288-pin DDR5 ECC UDIMMs.

Thermals and Power

The modules run at the nominal 1.1 V without a heat spreader, relying on case airflow for cooling. At stock DDR5 5600 speeds the power draw stays within the JEDEC baseline for unbuffered ECC DIMMs. No active cooling or additional voltage is required for standard operation.

Deciding Specification

The defining detail is the ECC unbuffered design at DDR5 5600 CL46. Only systems that specifically support unbuffered ECC DDR5 UDIMMs can use this kit; registered or non-ECC platforms will not accept it.

商品問答

Will this 64 GB DDR5 kit work in a standard desktop motherboard?

The modules are unbuffered ECC UDIMMs, so they only function on boards that explicitly support ECC unbuffered memory. Standard consumer desktops usually do not.

Does the kit require any special BIOS settings to run at 5600 MT/s?

JEDEC-standard DDR5-5600 CL46 at 1.1 V is the default profile; most compatible boards will apply it automatically without XMP or manual tuning.

Can I add these two modules alongside existing non-ECC DDR5 sticks?

Mixing ECC and non-ECC modules is not supported; all populated slots must use the same ECC type for the system to boot reliably.
