ASRock Z790 PG Lightning compatible DDR5 kit

This 64 GB kit contains two 32 GB DDR5 UDIMMs validated for the ASRock Z790 PG Lightning motherboard. The modules are non-ECC and unbuffered, using major OEM chips from Samsung, Micron or Hynix. Installation follows standard desktop procedures and requires no additional configuration.

DDR5 5600 PC5-44800 interface limits

The kit runs at DDR5 5600 with a CAS latency of CL46 and a default voltage of 1.10 V. As non-ECC unbuffered DIMMs they rely on the memory controller for error handling and signal integrity. Maximum throughput is bound by the PC5-44800 rating and the motherboard's supported memory topology.

64 GB capacity for heavy multitasking

Two ranks per module (2Rx8) provide density suited to content creation, virtualisation and large dataset workloads. The 64 GB total avoids the need to populate all four slots on the Z790 platform. Builds requiring more than 64 GB or ECC protection will need a different memory solution.

Questions about this item

Should I pick the 2x32GB kit or a single 32GB module?

The 2x32GB kit gives 64GB total and enables dual-channel operation on the ASRock Z790 PG Lightning, while a single 32GB module would run in single-channel mode.

What does the 5600 speed rating mean once the memory is installed?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V, delivering the rated transfer rate when the motherboard loads the default profile.

Does the 288-pin DDR5 UDIMM interface limit the usable speed on this board?

The 288-pin DDR5 UDIMM form factor matches the Z790 PG Lightning slots exactly, so the 5600 MT/s rating is not capped by the connector.
