ASRock Z790 Lightning WiFi DDR5 module

This 16 GB DDR5 UDIMM is validated for the ASRock Z790 Lightning WiFi motherboard. It targets builders upgrading that specific board with a single, non-ECC stick. The unbuffered design keeps installation straightforward for desktop users.

Thermals and power at stock settings

Operating at 1.10 V the module runs within standard DDR5 voltage limits. No heat spreader is fitted, so airflow across the PCB handles cooling. Power draw stays low at the rated 4800 MT/s speed.

Capacity and speed decide fit

The 16 GB capacity at DDR5 4800 with CL40 latency determines whether this matches the required memory configuration. Builders needing a different density or timing should verify their board's qualified vendor list.

商品問答

How do I install the 288-pin DDR5 UDIMM on the ASRock Z790 Lightning WiFi and what step is often missed?

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify in BIOS that the memory runs at 4800 MT/s and 1.10 V; the step often missed is enabling the XMP or EXPO profile to reach the rated speed.

What maintenance or replacement will the 1Rx8 16 GB module need over time?

No scheduled maintenance is required; keep the motherboard firmware updated for stability, and replace the module only if memory diagnostics report errors or if capacity needs exceed 16 GB.

What limit appears first during sustained workloads on this CL40 1.1 V kit?

The primary limit is the fixed CAS latency of 40 cycles at 4800 MT/s, which caps throughput before thermal throttling becomes a factor on this unbuffered, non-ECC UDIMM.
