Is this set up correctly?

My Regedit storeahci ErrorControl is correctly set to 0 for AHCI

But my storeahci StartOverride is set to 3 instead of 0.

0 being for AHCI according to this site. I have tried both of the mentioned fixes suggested in superuser and neither worked. I set my StartOverride string to 0. Reboot, go into bios and make sure AHCI is still selected...which it is. In fact its NEVER been set to IDE. I set it AHCI before the first boot when i built my rig. Which really puzzles me.

Moving on... Samsung Magician says that AHCI IS enabled as does my BIOS (Sorry, dont have a screenshot of my bios, but trust me when i say it is)


Furthermore, here are two sets of test results from Samsung Magician as well as CrystalDiskMark.

CrystalDiskMark Test.



As you can see, Samsung Magician asks me to make sure it is "Performance Optimized" which it clearly is above in the Drive Information snapshot. "Your OS is configured to maximize SSD Performance." It also states that "AHCI mode is ON"

Lastly, since I feel as if I may be missing something I have included the S.M.A.R.T status for the drive in question.



If you could use any other information please let me know, I've been scratching my head about my benchmark scores for months.
