  • Validated for Supermicro SYS-531AD-I and C9Z790-CG workstations

Targeted System Compatibility

This 64GB kit is built for the SuperMicro SYS-531AD-I C9Z790-CG workstation. It delivers two 32GB DDR5 modules rated at 5200 MT/s with a CAS latency of 38. The modules run at 1.10 volts and use a 288-pin UDIMM form factor. They are unbuffered, non-ECC and use a 2Rx8 organisation.

Workstation Upgrade Focus

The kit suits IT professionals and enthusiasts upgrading the named SuperMicro platform. It is not for buyers who need ECC error correction or registered modules for a server board. It is also not for builders whose motherboard requires a heat spreader or a different pin count. Compatibility is validated only for the specified system.

Sustained Load Behaviour

Modules are stress tested under load before shipping to confirm stability during extended workloads. The 1.10 volt operation helps manage thermal output during continuous use. Without a heat spreader, airflow across the PCB becomes the primary cooling path in a fully populated chassis.

Questions about this item

Which motherboard slots and voltage must my board provide for this 288-pin DDR5 kit to operate at 1.10 V?

Your motherboard needs four DDR5 UDIMM slots running at 1.1 V; the kit installs in any two slots as a matched pair.

Will the 2Rx8 organisation of these modules work alongside any existing single-rank DDR5 DIMMs I keep in the other two slots?

Yes, dual-rank 2Rx8 modules can share a channel with single-rank sticks provided the board supports mixed-rank populations at 5200 MT/s.

After installation, how do I confirm the kit is running at the rated 5200 speed and CL38 latency?

Enter the firmware setup or run a system-information utility and check that the memory frequency reports 5200 MT/s with CAS latency 38.
