Yes, as Fernando said, I have detailed on how to use the 2 independants on board SATA controllers on ASUS Sabertooth x99.
Your motherboard is similar, so you have to use 2 Intel SATA Drivers of different branches for each one of these controllers.

@Oubadah
The discussion with Fernando started at #278 "Recommended AHCI.. "

@Oubadah
Here are the screenshots of the current Intel SATA and sSATA drivers I use on my SabertoohX99 platform.
Ctrl_1 does support RAID 0:


Ctrl_2 does support pure AHCI mode:


Hope, this help you to install the appropriate driver for your X99 motherboard.

If I remember correctly you can use the normal RST driver for the first controller (which also support RAID), but if you want to use the additional 4 ports of the second controller (AHCI) you need the RSTe as the regular RST driver only detects a max. of 6 ports.

@Oubadah
Please look again carefully what driver I have used for the CTRL 2 (sSATA) for my X99.
Yes, the X99 sSATA ports do not support Intel Rapid Storage Technology and RAID configurations, this is why you have to use the IRSTe v4.5.4.1030 WHQL (mode AHCI) for this controller.

@Oubadah

I don't understand why iASTORB v4.5.4.1030 works fine on my X99 and doesnot work fine on your X99 motherboard.

Yes Intel RST and Intel RSTe are confusing names.
RST drivers and RSTe drivers are totally different pieces of software.

For your board what sSATA driver does ASUS recommend to use ?

Here are 3 HWINFO64 screenshots details related to sSATA ports:




Is your BIOS up to date ?
Is your SATA Controller 2 BIOS settings correct ?

@stna1981

I agree with you, this what I have done on my Sabertooth X99 and it works perfectly.
