64GB DDR5 kit for ASRock Z790 boards

This 64GB kit contains two 32GB DDR5 UDIMMs rated at 5200 MT/s with a CAS latency of 38. It is built for ASRock Z790 Taichi, Taichi Carrara and Taichi Lite motherboards. The modules run at 1.1V and use a 2Rx8 organisation without ECC or heat spreaders.

PC5-41600 bandwidth ceiling

The DDR5 5200 standard provides a maximum transfer rate of PC5-41600. Real-world throughput will sit below that figure because of controller overhead and system latency. Builders needing higher sustained bandwidth must select a faster memory grade or a platform that supports overclocking beyond the rated speed.

Unbuffered UDIMM build and 288-pin fit

Each stick is a standard 288-pin unbuffered UDIMM without a heat spreader, so it fits tight CPU cooler clearances. The lack of ECC and registered buffers suits consumer desktop workloads but rules out use in servers or workstations that require error correction or registered modules.

Questions about this item

How do I choose between the 32 GB module size and the 64 GB kit capacity?

Each kit contains two 32 GB modules for a total of 64 GB; install both sticks to reach the full capacity on a supported motherboard.

What does the DDR5 5200 speed rating deliver in an actual system?

The modules run at 5200 MT/s with CL38 latency at 1.1 V, providing the rated bandwidth when the platform enables the DDR5 5200 JEDEC profile.

How does the 288-pin UDIMM interface limit installation options?

The 288-pin unbuffered DIMM fits standard desktop DDR5 slots only; it cannot be used in laptop SO-DIMM sockets or registered server slots.
