Asus Sabertooth 990FX/GEN3 R2.0

[NeoGen]

Dirk, the Adaptec 6405E does fit on my board (Gigabyte GA-MA790XT UD4P) but for some reason to whatever PCIE slot I plug it the boot error is always the same, it's something like "Adapter firmware is corrupted! You need to reflash the firmware on the card". I know this is not true because I take the exact same adapter, plug it to an older machine and it boots perfectly, detects hard drives and does everything. Using the Adaptec Firmware Utility it even verifies the firmware checksum to be correct but on my Gigabyte board it just refuses to work.

Upon looking around online I found a few threads of people with various RAID controllers having similar complains on several different Gigabyte motherboards, and some rumours say that the PCIE ports on this motherboard are somehow mainly dedicated to GPUs so their compatibility with other kinds of adapters is hit and miss. (It's hard to believe that but at this point I'm starting to almost believe it)

I tried all PCIE slots, tried enabling and disabling most of the boards features, tried upgrading the bios both on my motherboard to the latest version, and also the firmware of the RAID controller to 2 different versions but never got it to work right so I am giving up on it. I was wanting to upgrade anyway so this might be the sign that it's time to go ahead and do it.

I can't find anywhere to guarantee that it will work, but I have more faith on this Asus than on my Gigabyte, if nothing else just because mine is probably around 5yrs old already.
