I need two PCIE SSD and a RAID Controller,
but my board has only one M.2 slot and PCIE slot.
BIOS setup has only 2x8, PLX card is too expensive.

@efsg - what BIOS version are you using? I checked latest, and I see plenty of different options for this, some sets of which would be some hidden from you for that setting generally, but I don't see the specific ones you show, so I think you're not using the BIOS I looked at
Also, you can use 2x8, that will work fine for 4x4 setup

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM
I view the forum like this, please bump your thread 1x every 24-48 hours if no reply
