Supermicro C9Z790-CG memory kit

This 64 GB kit contains two 32 GB DDR5 UDIMMs built for the Supermicro C9Z790-CG motherboard. It targets workstation and server builders who need reliable capacity for demanding workloads. The modules are validated for system-specific compatibility and stability.

Unbuffered non-ECC 288-pin design

Each module uses a 288-pin UDIMM form factor without a heat spreader, keeping the profile low for dense configurations. The unbuffered, non-ECC layout suits desktop and workstation platforms that do not require registered or error-correcting memory. Major OEM chips from Samsung, Micron or Hynix underpin the build quality.

DDR5 5600 at 1.1 V with CL46 latency

Rated at DDR5 5600 (PC5-44800) with a CAS latency of 46, the kit operates at 1.10 V for efficient power draw. The 2Rx8 organisation supports high-density performance under sustained loads. Rigorous stress testing aims to deliver stable thermals and quiet operation in normal use.

Questions about this item

What DDR5 speed and CAS latency does this kit run at?

The modules operate at DDR5 5600 (PC5-44800) with a CAS latency of CL46 at 1.10 V.

Does the Supermicro C9Z790-CG board accept 288-pin UDIMMs with a 2Rx8 layout?

Yes, the kit uses standard 288-pin DDR5 UDIMMs in a 2 x 32 GB 2Rx8 configuration that matches the motherboard slots.

How do I install the two 32 GB sticks so the board runs them in dual-channel mode?

Seat each module firmly in the paired DIMM slots indicated in the C9Z790-CG manual until the retention clips click on both sides.
