64 GB DDR5 kit for ASRock Z790

This 64 GB kit contains four 16 GB DDR5 modules rated at 5600 MT/s with CL46 latency and 1.10 V operation. It is built for the ASRock Z790 PG Lightning motherboard and uses unbuffered non-ECC UDIMM modules.

288-pin UDIMM modules without heat spreaders

The package delivers four bare 288-pin UDIMM sticks using 1Rx8 Samsung, Micron or Hynix ICs. No heat spreaders are included so clearance stays minimal inside compact builds.

64 GB capacity headroom for heavy workloads

Four ranks of 16 GB each give ample space for virtualisation, content creation and large datasets. Systems needing more than 64 GB or registered ECC memory will require a different solution.

Questions about this item

Will the 1Rx8 DDR5 modules need any firmware updates or chip replacements over time?

The 1Rx8 DDR5 modules are solid-state with no moving parts or firmware to update; they require no scheduled maintenance or chip replacements.

What limit appears first when the 5600 CL46 kit runs sustained workloads?

The CL46 latency at 5600 MT/s is the primary timing ceiling; bandwidth and voltage (1.10 V) remain stable within JEDEC spec during extended use.

How much heat and power does the 64 GB kit produce when running all day without a heat spreader?

At 1.10 V the four 16 GB modules draw minimal power and run cool enough for standard case airflow; no active cooling is required.
