GA EP43T-UD3L SATA/AHCI doesn't work anymore, only IDE

[Konally]

I bought an EP43T-UD3L from Newegg about 3 years ago, and well due to overclocking of a quad core, the 12v outlet burned out when I ran a maximum power and heat consumption test with prime95 to check for stability. I recently replaced the motherboard and it was the exact same one, the only difference now was that the 6 SATA ports that were orange were now blue. Everything always worked when I did a new installation of Windows 7, but now I can only run the OS in IDE mode even though the bios has an option to switch to AHCI.

I'm not sure what drivers are missing from this motherboard with the blue sata ports, but the one with the orange sata ports immediately let me install the intel rapid storage software after installation of windows 7. Now it says the system doesn't meet the minimum requirements to install the software. I know that something is missing about this motherboard with the blue sata ports because when the one with the orange sata ports burned out I switched them on the same installation without having to even do a repair install and it was running in ahci mode, still.

Now that I've done a new installation (when I did the installation it was already in ahci mode) ahci doesn't work anymore it gets stuck on the bios loading screen and hangs there forever.

For anyone that works here and has worked on the EP43T-UD3L motherboard with the orange sata ports, do you know what was taken away from the EP43T-UD3L board with the blue sata ports? If I can figure that out I may be able to get sata and ahci working like it did on the orange sata port one.

There are four motherboard versions: 1.0, 1.1, 1.3, and 1.4
Check the revision number for your motherboard in the lower left rear corner, near the lowest pci slot.
All the pictures on the Gigabyte site show 6 yellow sata connectors.
It will help if you double check the model number printed on your motherboard.
GIGABYTE - Motherboard - Socket 775 - GA-EP43T-UD3L (rev. 1.0)

[Konally]

The model number is D33006 and rev is 1.3

Oh so those are yellow? I thought they were orange wow.

[profJim]

I won't argue with yellow versus orange, it depends a lot on the ambient light.
What threw me was your comment:

the only difference now was that the 6 SATA ports that were orange were now blue

Boot into the bios and press CTRL + F1 keys at the same time. The bios screen will quickly flash and then go to the Integrated Peripherals screen. Check to see if you have the following bios options:

• Sata AHCI Mode
• Sata Port0-3 Native Mode

If both of these bios options are available, you will boot into windows to make a minor windows registry change.
Before you edit the registry, there will be a couple of steps to help protect you from yourself.

[Konally]

Yes those two options were available.

Yeah and the EP43T-UD3L with the blue ports looks exactly like this EP43T-USB3

[profJim]

I don't know, the EP43T-USB3 sata port color looks like it's really.......
blue.

Read and understand the AHCI : Enable in Windows 7 / Vista - Windows 7 Forums tutorial before starting.

A quick summary of the procedure:

1. Use window's Regedit to change the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\servic es\msahci registry key value to 0 (zero).
2. Save the change to the registry.
3. Boot info the bios immediately, do NOT boot back into windows.
4. Make the following bios changes:
   
   a) set Sata AHCI Mode = AHCI or ENABLED
   b) set Sata Port0-3 Native Mode = ENABLED
5. save bios settings and exit the bios
6. boot into windows, letting windows install the AHCI drivers
7. pray that everything works okie-dokie

Any questions?

I did all of what you asked and after that it hangs at the bios loading screen just when it's about to load up the devices, it shows:

23

Controller Bus#00, Device#1F, Function#02: 06 Ports, 03 Devices_

and then it hangs forever

[profJim]

Have you confirmed that both bios settings in step #4 are properly set?
Did you follow the exact steps in the windows 7 forums tutorial?
Do you have any usb devices attached that aren't needed for booting in windows, other than the keyboard and/or mouse?
Is the number 23 near the upper right corner of the screen?
