Hi, would this build work for a Hackintosh to run either Sierra or High Sierra?

• Motherboard: Asus H110M-A Socket1151.
• CPU: Intel Core i5-7500.
• RAM: Crucial DDR4 16GB 2400MHz Ballistix Sport LT C16
• GPU: Gigabyte N105TG1 GAMING-4GD GTX 1050 Ti G1 Gaming.
• PSU: Antec VP-600P.
• SSD: Samsung 840 EVO 128GB.
• HDD: WD 1TB Green.
• Case: Coolermaster N400.
• Monitor: BenQ GL2460.

Does it matter if the RAM's speed is higher than the maximum on the motherboard? Would it just regulate to 2133MHz?

This build should work with MacOS Sierra 10.12.6 and High Sierra.

Your motherboard and CPU supports DDR4-2400 RAM, so the RAM should work at its native speed.
