System-Specific DDR5 Kit

This 64 GB kit contains four 16 GB unbuffered UDIMMs built for the ASRock Z790 Taichi Carrara Lite motherboard. It targets builders who want a matched set that has been validated for that specific platform.

DDR5 4800 Interface Limits

The modules run at the JEDEC base speed of 4800 MT/s with CL40 latency at 1.1 V. They do not support XMP or EXPO profiles, so frequency and timing cannot be raised through the BIOS on this kit.

288-Pin UDIMM Form Factor

Each stick uses the standard 288-pin DDR5 UDIMM layout with 1Rx8 organisation and no heat spreader. Buyers needing ECC, registered modules or a different pin count cannot use this product.
