**Official ABIT IP-35 Pro Review/Overclock/Guide Thread**

[Master of None]

Could please someone tell me why at bios (even 1.1) I have

SATA 1
SATA 3
SATA 2
SATA 4
SATA 5
SATA 6

Isn't supposed that the 3rd SATA must be 3rd and not 2nd?

Here is my best guess:

On the IP35 Pro the six SATA connectors are arranged in three stacks, two in each stack. 1, 3, & 5 are closest to the motherboard, 2, 4, & 6 are above. Like this:

6-4-2
5-3-1

If you look in Device Manager, IDE ATA/ATAPI controllers, you will see two ICH9 Serial ATA Storage Controllers. Controller 1 is 4 port and Controller 2 is 2 port.

So 1, 2, 3, & 4 are on Controller 1, and 5 & 6 are on Controller 2. But now also consider how they are mounted on the motherboard.

1 – next to MB - Controller 1
3 – next to MB - Controller 1
2 – above 1 - Controller 1
4 – above 3 - Controller 1
5 – next to MB - Controller 2
6 – above 5 - Controller 2

So there you have it:

SATA 1
SATA 3
SATA 2
SATA 4
SATA 5
SATA 6
