When the Sata works in ACHI mode, recently we found it might cause Blue Screen if FC running with Intel Sata Driver (Intel RST driver) v9.6. So far no problem with Intel sata driver v10.1 (latest version) or with Microsoft Sata Driver (msachi.sys).
The Intel sata driver v10.1 can be downlowned from

Note: The versions prior to v9.6 are not checked. There might also be problems in these old versions.
