Asus maximus ix hero does not recognize 240gb mp500 m.2 nvme

[gabak]

hi guys

I have a motherboard Asus maximus ix with intel core i7 32gb ram and two storage units Corsair MP500 of 240gb.

I want to get a raid 0 working using both M.2 NVMe pie gen 3 x4ssd.

I have this motherboard that will boot just fine using just one M.2 slot but it does not recognize the second one. Even do I installed windows 10 it wont see the other unit either.

I have the latest firmware version up today. I think 1007 or something like like I downloaded it 2 days ago.

I have enabled KIT1 & 2. also disable CSM. M.2_1 is in PCIE mode.

I don't know what else to do. I just swapped them just in case if one of the Corsair MP500 was bad but it is ok.

thank you in advance.

happy new year
