This has been going on for years..... Magician incorrectly detects and reports incorrectly the AHCI SATA emulation status of HP workstations running Samsung SSDs.  A free software tool that is accurate is AS SSD, and if you go to this link and go down about 1/2 way you can see the difference between having or not having AHCI drivers installed:

With the correct system install method virtually all HP workstations let you run in IDE (legacy), and some let you run in AHCI mode by itself, but most instead give you IDE and a "RAID + AHCI" option in BIOS.  Both  HP and Intel recommend that second setting.  To make things even more confusing the BIOS in some HP workstations gives the options of IDE or "RAID"  (which actually means RAID + AHCI just like "RAID + AHCI" meant).  It took me quite some time to finally figure this all out.

HP sends their workstations out with the cloned HP builds having both the RAID and the AHCI drivers installed (plus the IDE drivers), but if you do a clean install from a Microsoft system builder DVD you have to make sure to first set BIOS to "RAID + AHCI " or ("RAID" if that is what your BIOS offers instead) so you get the full set of drivers for IDE, RAID, and AHCI.  This is a situation where what you set in BIOS then very much determines what gets installed during the OS load.  Setting that correctly keeps all your options open, and you can always go back into BIOS and subselect IDE ("IDE Separate" usually) if you need legacy mode for some reason.  You should then switch back to the more advanced drivers later.  For example, I've needed to do that for difficult SSD firmware updates, and even have needed to change SATA emulation in BIOS to "IDE separate" and attach the SSD to the SATA 0 position to update firmware in..... yes.... some Samsung SSDs recently.  

So, don't trust Magician on this.....  get the free AS SSD utility and it will give you an accurate answer.  As for why Samsung makes finding the latest version of Magician hard to find and confusing when you find it..... well, that is why I like Intel SSDs and the Intel Toolbox software so much better.
