64GB DDR5 5600 RDIMM

This 64GB DDR5 5600 module is an ECC Registered DIMM designed for server platforms. It operates at 1.10V with timings of 46-45-45-89 and includes on-die ECC plus side-band ECC for data integrity. A dedicated temperature sensor and plug-and-play support simplify deployment in qualified systems.

Suited for multi-channel server builds

Builders populating Intel W890 or AMD TRX50 platforms with registered memory will match the required module type and error-correction features. Systems that require unbuffered UDIMMs, non-ECC memory, or lower-density modules cannot use this RDIMM. Workstations limited to consumer memory specifications should look elsewhere.

288-pin DDR5 RDIMM form factor

The module uses the 288-pin DDR5 RDIMM interface, so the motherboard must provide registered DDR5 slots with matching electrical and mechanical specifications. Compatibility depends on the board and CPU combination supporting registered ECC memory at this density and speed.

Questions about this item

How much heat does the 1.10V DDR5 5600 module produce under sustained load without a heat spreader?

The module runs at 1.10V and includes a dedicated temperature sensor for monitoring, though it has no heat spreader.

What motherboard chipset and slot type are required to install this 288-Pin RDIMM?

It requires a motherboard with DDR5 RDIMM slots supporting Intel W890 or AMD TRX50 chipsets for quad-channel operation.

Can this CL46 registered ECC DDR5 module run alongside older DDR5 modules at a lower speed?

Yes, Plug-and-Play support allows it to downclock, but mixing with different timings or unbuffered modules is not recommended.
