  • 16GB DDR5 4800 memory boosts desktop responsiveness
  • CL40 CAS latency at 1.1V reduces power draw per module
  • Single-rank 1Rx8 layout simplifies compatibility with SuperMicro boards
  • 288-pin UDIMM form factor fits standard DDR5 desktop slots
  • Validated for SuperMicro SYS-531AD-I and Super C9Z790-CG workstations

Compatible SuperMicro DDR5 Upgrade

This 16GB DDR5 module is built for SuperMicro desktop workstations such as the SYS-531AD-I and Super C9Z790-CG. It delivers 4800MT/s speed at CL40 latency with a low 1.10V operating voltage. The unbuffered UDIMM design fits standard 288-pin DDR5 slots.

Builders needing ECC or registered memory

Buyers who require error-correcting code or registered modules for server-grade stability should look elsewhere. This stick is non-ECC and unbuffered, so it suits standard desktop workloads but not those specific needs. Systems needing multiple ranked DIMMs may also prefer a different configuration.

Single-rank 1Rx8 organisation

The memory uses a 1Rx8 layout with major OEM chips from Samsung, Micron or Hynix. This rank structure influences compatibility with the SuperMicro motherboard memory controller. Verify that your board supports single-rank 16GB UDIMMs before purchase.

Questions about this item

Will the DDR5 UDIMM need a heat spreader added later for sustained workloads?

The module ships without a heat spreader; SuperMicro chassis airflow is designed to cool bare DDR5 UDIMMs at 1.1 V, so no aftermarket spreader is required.

What limit appears first when the 1Rx8 module runs continuously at 4800 MT/s?

The CL40 latency ceiling is reached before bandwidth saturates, so sustained throughput tops out at the rated PC5-38400 ceiling.

How much extra heat and power does the 16 GB stick add when the workstation runs all day?

At 1.10 V the stick draws only nominal DDR5 power and adds minimal heat; the SuperMicro platform’s standard cooling handles the load without fan-speed changes.
