Compatibility with ASRock Z790 Taichi Carrara Lite

This 64 GB kit uses two 32 GB DDR5 4800 modules tested for the ASRock Z790 Taichi Carrara Lite motherboard. It runs at 1.1 V with CL40 latency and requires no heat spreader for standard operation.

Buyers needing non-ECC unbuffered DDR5 for this

The kit fits builders who want validated stability on the specified ASRock platform. It does not suit systems requiring ECC, registered modules, a different pin count, or a voltage other than 1.1 V.

DDR5 4800 speed with CL40 timing at 1.1 V

The 4800 MT/s data rate and CL40 CAS latency define whether the memory matches the motherboard's supported profile. Verify the board's qualified vendor list for exact compatibility before purchase.

Questions about this item

Will the 288-pin DDR5 modules fit the four DIMM slots on my ASRock Z790 Taichi Carrara Lite board?

Yes, each 32 GB stick uses the standard 288-pin DDR5 UDIMM form factor that matches the four slots on that motherboard.

What is the correct way to seat the two sticks so the board runs them at 4800 MT/s CL40?

Install one module in the first slot and the second in the third slot, press down until both side clips click, then enable the XMP profile in BIOS to reach 4800 MT/s CL40.

Do the 2Rx8 chips on these modules need any active cooling or periodic cleaning?

No heat spreader is fitted, so normal case airflow is sufficient; just remove dust from the slots and gold contacts with compressed air during routine PC cleaning.
