A 16 GB DDR5 UDIMM running at 5600 MT/s with CL46 latency and 1.1 V operation for ASUS ROG Strix Z790 motherboards
This 16 GB DDR5 UDIMM is built for ASUS ROG Strix Z790 motherboards including the Z790-A, Z790-E and Z790-F Gaming models. It targets desktop users who want a straightforward memory upgrade on those specific boards. The module runs at 5600 MT/s with CL46 latency at the standard 1.1 V.
The stick has no heat spreader and uses a 1Rx8 single-rank design, so it fits tight DIMM slots without clearance issues. Installation is a standard UDIMM insertion; the main risk is seating the notch fully before locking the retention clips. Mixing with existing kits of different speed or timing can prevent the system from posting.
Confirm the motherboard is exactly one of the listed Z790-A, Z790-E or Z790-F Gaming variants before ordering. Check how many DDR5 slots are free and whether the board requires modules to be populated in a specific order. The module is non-ECC and unbuffered, so it will not work in platforms that demand registered or error-correcting memory.
