System-Specific 64 GB DDR5 Kit

This NEMIX RAM kit provides 64 GB of DDR5 memory in a matched set of four 16 GB UDIMM modules. It is built for Supermicro desktop workstations such as the SYS-531AD-I and C9Z790-CG motherboards. The kit suits professionals who need validated capacity for memory-intensive workloads on these specific platforms.

Sustained-Load Behaviour at 5600 MT/s

Rated at 5600 MT/s with CL46 timings and a low 1.10 V operating voltage, the modules are stress-tested under load to maintain stability during extended compute sessions. The unbuffered, non-ECC design relies on the memory controller for error handling, so data integrity depends on the host platform rather than on-module correction.

Straightforward UDIMM Installation

Each 288-pin module seats in standard DDR5 DIMM slots without a heat spreader, keeping the profile low for tight clearances. Because the kit is system-specific, compatibility issues usually arise only when the motherboard or BIOS does not match the validated Supermicro models listed. Builders using unsupported boards may encounter training failures or reduced speeds.

Questions about this item

How much power does the 1.1 V DDR5 kit draw when the system runs continuously?

Each module operates at 1.10 V, the standard DDR5 voltage, so power draw stays at the JEDEC baseline for 5600 MT/s UDIMMs.

What motherboard slot and chipset must I already have for this 288-pin kit to work?

You need a board with four DDR5 UDIMM slots and a chipset that supports 5600 MT/s non-ECC memory, such as the Z790 platform used in the SYS-531AD-I.

Will the CL46 1Rx8 modules work alongside older DDR5 DIMMs I already own?

Mixing ranks or latencies can prevent the board from training at 5600 MT/s; for guaranteed stability use all four modules from this kit together.
