Intel RST - Newest AHCI/RAID Driver by CPU Generation

Official support for various Intel chipsets gets deprecated after some period of time. Here is the most current version officially supported by each generation:

8thCoffee LakeIntel 300 Series16.5.1.10307/19/2018

This was derived from the iaAHCIC.inf file with each x64 release. Pretty certain if you put a 2nd gen (Sandy Bridge) CPU in a supported 3rd gen (Ivy Bridge) motherboard you would use the corresponding 3rd gen driver.

Please comment if you find any different information.
