Once again, I'd love to thank you.
This is something what I suspected so far but I lack the kind of knowledge in this area. Hardware these days have changed so fast that I think I start to miss some knowledge regarding its limitations and know-hows

That is correct, yes. It can be a bit of a juggling game but ASRock allows quite
a bit of flexibility and options to extract the most out of your available lanes.

Good luck ]]> Mon, 01 Apr 2024 06:14:03 +0000 https://forum.asrock.com/forum_posts.asp?TID=34207&PID=116462&title=sata-1sata-4-disappears-whenever-i-use-pcie3#116462 https://forum.asrock.com/forum_posts.asp?TID=34207&PID=116460&title=sata-1sata-4-disappears-whenever-i-use-pcie3#116460 Author: Reptilian

I think I got the info here:

*Supports Intel® Volume Management Device (VMD)
Supports NVMe SSD as boot disks
If M2_1 is occupied, PCIE1 will downgrade to x8 mode.
If PCIE2 is occupied, M2_1 will be disabled.
M2_1 and M2_2 cannot be populated simultaneously.

**If PCIE3 is occupied, SATA3_0~3 will be disabled.""

Is this my case?

So I got to make sure my M2 does not occupy M2_1 slot so as to use PCI-E 2? ]]> Mon, 01 Apr 2024 02:31:04 +0000 https://forum.asrock.com/forum_posts.asp?TID=34207&PID=116460&title=sata-1sata-4-disappears-whenever-i-use-pcie3#116460 https://forum.asrock.com/forum_posts.asp?TID=34207&PID=116459&title=sata-1sata-4-disappears-whenever-i-use-pcie3#116459 Author: Reptilian

I'm very impressed by your answer (would u plz tell me where I can find the info about PCIE-3 sharing with SATA 1-4 channels?)

I'd also like to ask what if I use PCI-E 2 channel for my LAN-card, would this work? Is PCI-E 2 channel free in my case (I have devices connected to SATA 5-6)]]> Mon, 01 Apr 2024 02:08:57 +0000 https://forum.asrock.com/forum_posts.asp?TID=34207&PID=116459&title=sata-1sata-4-disappears-whenever-i-use-pcie3#116459 https://forum.asrock.com/forum_posts.asp?TID=34207&PID=116458&title=sata-1sata-4-disappears-whenever-i-use-pcie3#116458 Author: Xaltar

I am using AsRock Z790 TaiChi Intel I9 48GB RAM x2 with 4090 in PCIE-1

My M.2, 1, 3, 4, 5 are fully used with 4TB M.2
I have devices connected for SATA 1, SATA 2, and SATA 3, SATA 6
Whenever I plug in any card, LAN-card, M.2 Extension card in PCI-E 3, my SATA 1-4 drives will 'disappear'on my BIOS, in which case I can't boot my windows (my bootable drives are in SATA -1 (?))

Can you tell me what caused the probelem ? ]]> Sun, 31 Mar 2024 22:50:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=34207&PID=116456&title=sata-1sata-4-disappears-whenever-i-use-pcie3#116456
