  • 128 GB total capacity from four 32 GB modules
  • DDR5 5600 speed rated at PC5-44800 for high bandwidth
  • CL46 latency at 1.1 V for efficient operation
  • 2Rx8 dual-rank organisation on 288-pin UDIMM form factor
  • Validated for Supermicro MBD-C9Z790-CGW workstation motherboards

Capacity and purpose

This 128 GB kit contains four 32 GB DDR5 modules rated at 5600 MT/s with CL46 latency and a 1.1 V operating voltage. The 2Rx8 unbuffered UDIMMs are built for Supermicro desktop and SuperWorkstation platforms such as the MBD-C9Z790-CGW.

Who it suits and who it does not

Builders upgrading compatible Supermicro systems gain a straightforward path to 128 GB of memory without ECC or registered signalling. Buyers who need error-correcting code, registered modules, or a different pin count should look elsewhere.

What the kit changes

The matched four-module package enables quad-channel bandwidth on supported boards and eliminates the guesswork of mixing individual sticks. No heat spreaders are included, so airflow around the bare modules must be adequate for sustained loads.

Questions about this item

Will this 128GB kit work in my Supermicro MBD-C9Z790-CGW motherboard?

Yes, the kit is validated for the Supermicro MBD-C9Z790-CGW and other Supermicro desktop workstation boards that accept 288-pin DDR5 UDIMMs.

Can I keep my existing DDR5 modules and add this 4x32GB kit alongside them?

Mixing kits is possible only if the motherboard supports the total capacity and the modules share the same 5600 speed, 1.10V voltage and CL46 timing; otherwise the system will default to the slowest common settings.

How can I confirm the 5600 MT/s speed and CL46 latency are active after installation?

Open the BIOS or a tool such as CPU-Z and verify the memory reads DDR5-5600 with a CAS latency of 46 at 1.10V.
