16 GB DDR5 module for ASRock Z790 boards

This 16 GB DDR5 UDIMM runs at 4800 MT/s with CL40 latency and 1.10 V operation. It is validated for ASRock Z790 Taichi, Taichi Carrara and Taichi Lite motherboards. The single-rank 1Rx8 organisation suits desktop systems needing a straightforward capacity increase.

Unbuffered non-ECC stick without heat spreader

The module uses a bare 288-pin PCB with no heat spreader, keeping the profile low for tight CPU cooler clearance. Unbuffered non-ECC design means it installs like standard desktop memory and works with consumer chipsets. Major OEM DRAM from Samsung, Micron or Hynix underpins the build.

DDR5 4800 speed ceiling and single-module limit

At 4800 MT/s the module sits at the base DDR5 data rate, so bandwidth scales with the memory controller rather than XMP profiles. A single 16 GB stick fills one slot; adding a second module is required for dual-channel throughput. No ECC function is present, so error correction is not available for critical workloads.
