MOBO = EVGA with nForce 610i/GeForce 7050 chipset.

I Installed this chipset driver after windows install - http://www.nvidia.com/object/nforce-vista-win7-64bit-15.56-driver.html
IDK about nForce, you should make a thread as someone else may be able to help more.

yea, just pop it in the PC with the sata mode set to ide, make sure it boots and there is no driver conflict, do the registry change and boot backup in AHCI mode.

Hello, sorry to bump an old thread, but I thought I would post because this might be useful for someone else with an AMD 990FX motherboard running Windows 7 64 Bit-Ulitmate

I thought I would give it a go to change my AHCI mode RAID stripe configured in Disk Management as a Dynamic Disk from within Windows, and turn it into the software RAID provided on the controller on my motherboard. I searched up Google and found this thread...

I have an AMD 990FX chipset with SB950 southbridge. My motherboard is an ASUS Sabretooth 990FX with BIOS version 1208.

I carried out the steps provided on this link: http://superuser.com/questions/300035/how-to-install-amd-raid-driver-after-windows-installation

And edited the ini file as follows:
Code:

;RAID - non RAID 5 mode;
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4392&CC_0106
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4392&CC_010601

;RAID - RAID 5 mode;
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4393&CC_0106
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4393&CC_010601

%ATI_Raid_ControllerDesc%=NODRV,SCSI\ProcessorAMD_____

;RAID - non RAID 5 mode;
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4392&CC_0106
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4392&CC_010601

;RAID - RAID 5 mode;
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4393&CC_0106
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4393&CC_010601

;AHCI MODE;
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4391&CC_0106
%NapaDesc%=Napa_Inst,PCI\VEN_1002&DEV_4391&CC_010601


After ensuring the driver was installed whilst having the BIOS enabled on AHCI and checking Device Manager's Hardware ID, which was reported as PCI\VEN_1002&DEV_4391&CC_0106 or AHCI mode, then noticing the disk controller was now not visible under IDE ATA/ATAPI Controllers anymore but it was showing as an SCSI Controller where you'd expect to find your system's RAID controllers. I also checked the registry and even made my own keys, because the existing keys were slightly incorrect on my install of Windows - I double checked everything then rebooted for the RAID BIOS change.

I was now excited by the fact that I 'could' use RAID from the motherboard and not Windows! I rebooted and changed the BIOS to RAID, rebooted again before loading Windows and went back into to the BIOS to ensure I was booting from the boot drive, I didn't configure any RAID arrays with the motherboard software ROM, I just wanted to see if Windows would load but the Blue Screen of Death was proud to be home!

I tried to work this out for several hours, with changes to the INI and delving into the registry moving Class GUID repository lookups from Windows update to my edited INI, but nothing I tried could get this working. I don't know if the INI which I edited is wrong or something, but as soon as I enabled RAID in the BIOS nothing worked... And Windows 7 disks needed to recover my install (multiple times).

I wonder if someone would take a look at this and let me know if I'm going wrong? Or if they can verify they can't get the driver to change operation in conjunction with their motherboard function on a 990FX chipset?

It would be appreciated.

Hey, i just spent around 4 or 5 days non stop trying to change my system from being installed on a single 240gb ssd to raid 0 on 2 ssds totaling around 480gps, now i didnt want to start from scartch (reinstalling windows, programs, etc) so initially i had windows 7 ultimate 64 bit installed with native ide on 1 ssd, now the problem was that i ran out of that 240gb, so i read into it that instead of buying a ssd thats 480gps it would be more beneficial to buy the same ssd and turn it on raid 0, performance boost and cheaper, so i brought another one, backedup the ssd drive into an image on another hdd, setup the raid array, recovered the image onto the new raid array, but from there on i had problems, anyway, after researching and going through 100s of pages on the new about reg tweaks, raid setups, windows settups, installing programs and so on, since everywhere i read each guide still had so much stuff left out, i wrote out the perfect guide on it, so that i know exactly whats what so i dont get stuck again, anyway, i thought its only right that i share this knowledge to the world to save people time and know how to go about this, so here is the guide, just a tip, read every single thing to educate yourself the most and know exactly what is what:

first of all disconnect all sata ports, connect the drive that we will backup, and the drive that we will backup to, to port 4, 5, because we will later enable ports 0, 1, 2, 3, 6, 7 to raid and if the drives were connected those ports, windows wouldve rebooted on "windows starting", by default with this system raid is disabled, if it isnt disable it then start the pc, keep pressing del to get into the bios, go to integrated peripherals, go to onchip sata controller, enable, onchip sata type, native ide, onchip sata3.0 support, enable, onboard gsata/ide ctrl, enable, onboard sata/ide ctrl mode, ide, press f10, press enter, reboot to windows, go to start, in the search box type regedit, press enter, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\, for the following list, click on the folder of the same name from the list, then within the folder on the right, double click on start and change the paremeter to the information from the list:
atapi Start = 3 (THIS IS IDE, HAVE IT ON 3 SINCE 3 MEANS OFF)
iaStor = 3 (THIS IS INTEL RAID, HAVE IT ON 3 SINCE 3 MEANS OFF)
iastorV Start = 0 (THIS IS WINDOWS RAID, HAVE IT ON 0 SINCE 0 MEANS ON)
intelide Start = 3 (THIS IS IDE, HAVE IT ON 3 SINCE 3 MEANS OFF)
msahci Start = 3 (THIS IS AHCI, HAVE IT ON 3 SINCE 3 MEANS OFF)
pciide = 3 (THIS IS IDE, HAVE IT ON 3 SINCE 3 MEANS OFF)
once done go to file, exit, shut down the pc without force rebooting, so the software raid is now manually configured, installed and all ports will read the drives if set to raid, reboot, keep pressing del to get into the bios, go to integrated peripherals, onchip sata, raid (THIS ENABLES RAID ON PORTS 0, 1, 2, 3, BUT WINDOWS WONT BOOT WITHOUT THE NEXT CONFIGURATIONs SO DO IT TOO), onchip sata port4/5 type, sata as sata, (THIS ENABLES RAID ON PORTS 4, 5), onchip sata raid5 support, disable (THIS IS NECESSARY OTHERWISE WINDOWS WONT BOOT), onboard sata/ide ctrl mode, raid/ide, (THIS ENABLES RAID ON PORTS 6 AND 7, AND MAKES THE ONCHIP SATA BOOT UP, IT IS VERY NECESARY WE ENABLE THIS RAID, BECAUSE IF WE DONT TURN THIS ON THEN PLUG THE SATA CABLE INTO PORT 0, 1, 2, 3 WINDOWS WILL REBOOT, BUT WITH THE ONBOARD SATA/IDE CTRL MODE ON RAID/IDE, YOU CAN CONNECT IT TO PORTS 0, 1, 2, 3, 4, 5, 6, 7 AND WINDOWS WILL BOOT UP, now that the raid is setup through software and hardware you wont get errors like say you connect cd dvd drive to a raid configured port, that drive will encounter errors like when installing windows you will get an error saying: "a required cd dvd drive device driver is missing..." or when your recovering a backup using acronis "failed to read from sector 0 of hard disk 1", and other hard drives wont even be viewable), press f10, press enter, reboot to windows, once rebooted into windows, at the bottom right you can see a little green dot spinning, this is windows installing drivers for the raid controllers, once its done it will ask you to restart, so click on restart now, once back in windows, give it 5 minutes to see if windows will install more drivers automatically, if not turn of the pc, disconnect all the sata cables from the ports, and connect the drive we are going to back up to the blue port 0, the new ssd drive to port 1, the drive we are going to back up to to port 2 and a cd dvd drive to port 3, once again very necessary that we connect to the blue port as its sata 3 which means its 6gps rather then the white port which is sata 2 3gps, once done, turn the pc on, again check if windows installs drivers, if it does and asks you to reboot, do so, repeat until it doesnt install any more, once thats done, go to start > all programs > acronis > acronis true image home > acronis true image home, back up system, at the top right click on multiple systems selected, then at further top right, click on click on switch to disk mode, check the source drive, in destination select the destination drive you want to write to, in the backup scheme, click on the blue hyperlink, in the backup method select full, at the bottom left check save the settings as default, click on the performance tab, in compression level click and drag to none, click on ok, click on backup now at the bottom right, this may take an hour or more, once done, click on the backup and recovery tab at the top, click on create bootable media, click on next, check everything, click on next twice, select your disc writer, click on next, put a compact disc into your disc writer, click on proceed, click on ok when done, make a note of the name, drive letter, model number, data size, of the source drive and the destination drive, close the program and shut down the pc, start the pc, now there will be a boot bios screen, then raid setup utility, on that screen, and only then (dont tap as it wont work) ctrl + f, press 2 to enter ld view / ld define menu, press ctrl + c, to scroll through the selection press up or down, to change the parameter space, change raid mode to raid 0, for stripe block, the higher the number the faster performance for larger files, for example video games, videos, and so on, whilst smaller the number is for smaller files like text files, word and so on, but since im a media person, video games, media, the best would be larger for me so choose 128 kb, now go down to the drive selection, press space to change the parameter to y, change to y to the drives you want in the array, press ctrl + y to save settings, then again, and change the name to programs, press enter, press ctrl + y again to erase the master boot record of those disks, press any key to use maximum capacity of the array, now you are done and can press esc to exit the setup, press esc then y to reboot, now to restore the image to the new hdd, disconnect all usb drives expect the mouse and keyboard, boot the pc and keep pressing 12 to enter boot menu, insert the compact disc in the disc writer, select cdrom, press enter, select acronis true image home, press enter, in recover click on my disks, navigate to the recovery file, click on next, make sure recover whole disks and partitions are checked, click on next, check everything, check the drive we are going to recover to (the raid array), click on next, click on proceed, the programs drive should have increase the capacity to max and the active partition should be the system reserved one, check restart the computer when recovery is completed, once done and back in windows, eject the disk, windows may install drivers again, once its done it will ask you to restart, so click on restart now, once back in windows, give it 5 minutes to see if windows will install more drivers automatically, if not turn off the pc, connect the rest of the drives to the sata ports, now turn on the pc and keep pressing del to enter the bios, advanced bios features, hard disk boot priority, change the new raid array to the top, press f10, press y, press enter to reboot, now that your back in windows, windows may install drivers again, once its done it will ask you to restart, so click on restart now, once back in windows, give it 5 minutes to see if windows will install more drivers automatically, if it doesnt, check that all the drives appear in my computer and are assigned the correct drive letter, if they are not, go to start, search, disk management, press enter, right click on each disk one by one at the bottom where the blue rows are, (excluding the raid array), change drive letter and path, click on remove, click on yes twice, repeat but this time add and assing the letter to the list above, including the cd dvd drive, once done, reboot the pc.

hope this helps you

How to: Change SATA Modes After Windows 7 Installation


Types of SATA modes:
  • IDE - Old, slower, it is simply a compatibility mode
  • AHCI - AHCI stands for Advanced Host Controller Interface. It makes Native Command Queuing (NCQ) along with hot-plugging or hot swapping through SATA Serial-ATA host controllers possible. NCQ is one of the important features of AHCI for SSDs. SSDs can process requests faster than HDDs. It can process so fast that the SSD could end up waiting for work. NCQ allows the OS/controller to request up to 32 simultaneous requests at once. So you basically get more performance from your drive over older IDE mode.
  • RAID - RAID stands for redundant array of independent disks, originally redundant array of inexpensive disks. It is a means by which your PC uses multiple disks as if they were one, either to increase performance, safeguard against disk failures, or both. RAID mode has all the advantages of AHCI mode. There are four main factors of a RAID setup: striping, which spreads data across multiple drives, mirroring, which copies the data to more than one disk, space efficiency, which is how much of the total space is available to use, and fault tolerance, which is a measure of how well protected the RAID array is against disk failure.
The Problem:
The issue with changing the SATA modes is they need to be enabled in the BIOS prior to OS installation; doing so after you have installed the OS will disable the PC. The reason why is Windows disables the drivers for the others that are not needed during installation. This tutorial will show you how to enable the different SATA modes after you have installed the OS.
Note: You may have to uninstall then reinstall any SATA drivers such as Intel RST or AMDs equivalent.
Change to AHCI mode from IDE mode: Warning: Spoiler! (Click to show)
You can use the MS Fix it tool or edit the registry yourself.
Link to tool here: (link)
Regedit:
  1. Exit all Windows-based programs.
  2. Press [Win] + R or take the RUN option from the start menu.
  3. Now type Regedit there and press Enter Key to open up the Registry Editor Window. (If you receive the User Account Control dialog box, click Continue.)
  4. Locate and then click the following registry sub key:
    Code:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci
    
  5. In the right pane right-click Start in the Name column and then click Modify.
  6. In the Value data box, type 0 [3 is default], and then click OK.
  7. On the File menu, click Exit to close Registry Editor.
  8. Restart your computer
  9. Go to UEFI/BIOS and enable AHCI, Save & Reboot
  10. Another restart will be required to finish the driver installation.
Change to ACHI mode from RAID mode: Warning: Spoiler! (Click to show)
  1. Exit all Windows-based programs.
  2. Press [Win] + R or take the RUN option from the start menu.
  3. Now type regedit there and press Enter Key to open up the Registry Editor Window.

Hello

I have OS windows 7 on a Corsair F120, I have added 2 Crucial V4 256gb and they are for games in raid0, I have them connected to Marvel Raid0, but I think they are a bit slow so I'm considering AHCI ---> RAID MODE in P67 BIOS.

So my OS is not RAID but I still need to choose RAID MODE in BIOS?

Also will the P67 give less load times for games?

Yes if any drives are in raid, raid mode has to be enabled whether its os or not doesnt matter has to be in raid mode. In marvel raid mode hmmm didnt know you could do that It has a marvell raid controller onboard? If I were you id use intel sata ports. To the second question I dont think chipsets have anything to do with game loading times at all (I could be wrong though). Great guide sean.

Yes, Marvel RAID configuration is loaded just after motherboard BIOS is completed and Exit.
The Motherboard has a Marvel chip added (2x Sata ports).

Also I'm not entirely sure if my game loading times change with the Intel P67 Raid0, I believe the small file write speed will double with P67 vs Marvel.

I'm a bit worried I do the change from AHCI - - - - > RAID something wrong and loose my windows 7 installation with all the apps in the process biggrin.gif

I'm a bit worried I do the change from AHCI - - - - > RAID something wrong and loose my windows 7 installation with all the apps in the process biggrin.gif
It should be fine and raid wont work without the change to raid mode unless you use the os raid which i dont suggest.

How to: Change SATA Modes After Windows 7 Installation


Types of SATA modes:
  • IDE - Old, slower, it is simply a compatibility mode
  • AHCI - AHCI stands for Advanced Host Controller Interface. It makes Native Command Queuing (NCQ) along with hot-plugging or hot swapping through SATA Serial-ATA host controllers possible. NCQ is one of the important features of AHCI for SSDs. SSDs can process requests faster than HDDs. It can process so fast that the SSD could end up waiting for work. NCQ allows the OS/controller to request up to 32 simultaneous requests at once. So you basically get more performance from your drive over older IDE mode.
  • RAID - RAID stands for redundant array of independent disks, originally redundant array of inexpensive disks. It is a means by which your PC uses multiple disks as if they were one, either to increase performance, safeguard against disk failures, or both. RAID mode has all the advantages of AHCI mode. There are four main factors of a RAID setup: striping, which spreads data across multiple drives, mirroring, which copies the data to more than one disk, space efficiency, which is how much of the total space is available to use, and fault tolerance, which is a measure of how well protected the RAID array is against disk failure.
The Problem:
The issue with changing the SATA modes is they need to be enabled in the BIOS prior to OS installation; doing so after you have installed the OS will disable the PC. The reason why is Windows disables the drivers for the others that are not needed during installation. This tutorial will show you how to enable the different SATA modes after you have installed the OS.
Note: You may have to uninstall then reinstall any SATA drivers such as Intel RST or AMDs equivalent.
Change to AHCI mode from IDE mode: Warning: Spoiler! (Click to show)
You can use the MS Fix it tool or edit the registry yourself.
Link to tool here: (link)
Regedit:
  1. Exit all Windows-based programs.
  2. Press [Win] + R or take the RUN option from the start menu.
  3. Now type Regedit there and press Enter Key to open up the Registry Editor Window. (If you receive the User Account Control dialog box, click Continue.)
  4. Locate and then click the following registry sub key:
    Code:
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\msahci
    
  5. In the right pane right-click Start in the Name column and then click Modify.
  6. In the Value data box, type 0 [3 is default], and then click OK.
  7. On the File menu, click Exit to close Registry Editor.
  8. Restart your computer
  9. Go to UEFI/BIOS and enable AHCI, Save & Reboot
  10. Another restart will be required to finish the driver installation.
Change to ACHI mode from RAID mode: Warning: Spoiler! (Click to show)
  1. Exit all Windows-based programs.
  2. Press [Win] + R or take the RUN option from the start menu.
  3. Now type regedit there and press Enter Key to open up the Registry Editor Window.
  4. If you receive the User Account Control dialog box, click Continue.
  5. Locate and then click the following registry subkeys:
    Code:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pciide
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msahci
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\atapi
    
  6. In the right pane, right-click Start in the Name column, and then click Modify.
  7. In the Value data box, type 0 [3 is default], and then click OK.
  8. On the File menu, click Exit to close Registry Editor.
  9. Restart your computer
  10. Go to UEFI/BIOS and enable AHCI, Save & Reboot
  11. Another restart will be required to finish the driver installation.
    Note: You might not have the last registry key (iastor) as this is installed in the registry with the intel raid drivers, the default windows 7 raid driver uses the iastorV key.

Hi Sean,

i'm one of the avid reader of your SSD Guide and really appreciate it, job well done thumb.gif also would like your advise regarding my plan of adding one more SSD with the same brand and specs on my current set up which is on my sig, Im planning to add another 128GB of Crucial M4 and configure to RAID 0, currently my SSD is configured to AHCI with latest firmware and running W7 Ultimate 64bit.

following your guide, i would like to know if
1. should I first connect the new SSD before proceeding to the registry to change the values AHCI to RAID 0?
2. which particular registry lines should i change? or each of those registry lines (values) shall be change?
3. I've already backup and made system disk of my current set up. Also from your guide biggrin.gif
4. my board is ASUS Sabertooth X58.

many thanks in advance and really appreciate it.
