I got this rig:
- Intel i7 2500K
- Gigabyte Z68X-UD3H-B3 rev1.0
- Gigabyte GTX970-G1
- 16GB Corsair XMP
- Windows 7 x64
Now I added a LSI SAS3801E Host Bus Adapter to connect a LTO-drive, though while the LEDs of the card light up, I don't get to see the card's BIOS nor does Windows detect the card.
I tried already switching PCI-gens in the UEFI and turned off the onboard-GPU, nothing.
Can it be that Gigabyte never thought about other hardware than GPUs for the second x16 slot? They also only connected half of the slot, so it is practically a x8-slot despite the length. GPU and the CPU-cooler block also each one x1 slot, so I'm left with just 1 spare PCIe x1 slot and 2 PCI-legacy slots.
Is there anything I could try to get the LSI-card working? Or is there a working alternative like USB2SAS or SATA/eSATA2SAS? I'm out of ideas here myself...
