Solved SATA settings in bios for ASUS P7P55D-E LX? Tags: Asus BIOS NAS / RAID Motherboards Last response: July 21, 2010 10:18 PM in Motherboards Share ricno June 22, 2010 9:04:00 AM I am wondering if I should change anything in the Storage section in the BIOS of my new Asus P7P55D-E LX motherboard? I have the option to choose "Configure SATA as": IDE, RAID or AHCI. As for RAID I am not planning to use it, but what would be the difference between IDE and AHCI? The default setting seems to be IDE. Motherboard: ASUS P7P55D-E LX Harddisk: SAMSUNG Spinpoint F3 1TB Dvd: Sony NEC Optiarc DVD±RW burner AD-7240S Operating system: Windows 7 More about : sata settings bios asus p7p55d suat a b Ĉ ASUS a b V Motherboard June 22, 2010 12:08:54 PM AHCI is best for Win 7 and SATA components. IDE is only good for Win XP which does not have native AHCI support and requires F6 method and floppy diskette during install. m 0 l ricno June 22, 2010 12:24:48 PM suat said:AHCI is best for Win 7 and SATA components. Thank you for your reply! So AHCI should be selected in BIOS for the SATA drives, would that be done before the operating system installation normaly? m 0 l Related resources Asus P7P55D-E LX not booting after BIOS update - Forum Bios Settings Need Help/ i5 750 Asus P7P55D-E Pro - Forum ASUS P7P55D-E LX compatibility - Forum ASUS P7P55D-E LX Incompatible with Windows 8? - Forum Asus P7p55d-e Lx with corsair hydro h80i - Forum Can't find your answer ?

But you can install the OS first and then change a setting in Registry and then set AHCI in BIOS. Otherwise, Win 7 does not boot. I prefer to set AHCI first in BIOS. Why mess with registry settings afterwards. m 0 l ricno June 25, 2010 9:53:31 AM suat said:It is best to set AHCI in BIOS and then install the OS.

Why mess with registry settings afterwards. I shall try the registry method first, to avoid reinstallation of the operating system. Thanks for the information about AHCI/IDE. Do you know what kind of performance difference there could be? m 0 l Best solution suat a b Ĉ ASUS a b V Motherboard June 26, 2010 7:39:41 AM AHCI supports hot plug-and-play operation of the drives and NCQ if your hdd supports it. Normally you do not see much difference for all practical purposes of disk operation. I guess you know what registry keys to modify in switching from IDE to AHCI after OS has been installed.
