I have the Nforce 790u SLI Ultra Mainboard. I tried to run my SSD in AHCI-Mode but it seems, that my Board doesn`t support this mode. So someone told me, that i should try to run it in RAID-Mode (Jbod) because this would use the features of AHCI. Is this true? I tried to change settings in Bios to RAID-Mode. But when I pressed F10 for RAID-Config-Menue on startup, I found nothing about JBOD. Can you please help me?
The next thing I want to know is, if the ASUS U3S6 PCIe-Card is working on my mainboard. This seems to be the only way to use my SSD in AHCI-Mode for using NCQ AND TRIM. With the nvstor64.sys driver NCQ is working but TRIM is not, with the MS-PCI-IDE driver TRIM is working but NCQ isn't. Is there a way to use both features?
Is it possible to use the JMicron-AHCI-Mode for my SSD? Is the JMicron Controller a fast controller or should I use IDE-Mode in future?
Sorry for my Engish, but I'm from Austria and didn't use it for a long time! :-)
For everybody who is searching the web for an answer:
IT IS POSSIBLE to run AHCI-mode on an Nforce 790i SLI ULTRA mainboard! The sata port which supports AHCI is the red one (very close to the grafics card port). To become the system booting on this port you have to chose "boot other device" from the "advanced bios settings" menue! This port runs with the standard AHCI driver included in WIN 7. Unfortunately the jmicron controller is not very fast for sequentiell reading. But this option increases my results in 4K-tests more than 100%! I hope I could help you!
