Thanks for the update corsair17. I was looking into possible causes for you but
got distracted by holiday prep and forgot about your post, sorry.
Step 1 in any situation like this is always reseat everything relevant to the issue

Glad you got it sorted out.]]> Wed, 17 Dec 2025 17:47:20 +0000 https://forum.asrock.com/forum_posts.asp?TID=113411&PID=200625&title=b450-itx#200625 https://forum.asrock.com/forum_posts.asp?TID=113411&PID=200618&title=b450-itx#200618 Author: corsair17

I re-seated by PCI-E riser cable and it's reporting x16 now. Problem fixed.]]> Wed, 17 Dec 2025 09:01:54 +0000 https://forum.asrock.com/forum_posts.asp?TID=113411&PID=200618&title=b450-itx#200618 https://forum.asrock.com/forum_posts.asp?TID=113411&PID=200612&title=b450-itx#200612 Author: corsair17

And if it matters, I have a 5700X3D CPU installed. The motherboard BIOS is flashed to the latest version (10.43 Beta).]]> Mon, 15 Dec 2025 05:37:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=113411&PID=200612&title=b450-itx#200612 https://forum.asrock.com/forum_posts.asp?TID=113411&PID=200611&title=b450-itx#200611 Author: corsair17

I have a 9070 XT installed on my Asrock B450 ITX motherboard. The AMD driver software is reporting that the PCI-E bus is running at PCI-E 3.0 x8 despite the motherboard supporting PCI-E 3.0 x16 mode. I heard from other brands that installing a M.2 drive will reduce the GPU PCI-E slot speed from x16 to x8, but I'm not sure whether this applies to the Asrock B450 ITX specifically because I can't find any mention of this in the motherboard manual. I do have a M.2 SSD installed.]]> Mon, 15 Dec 2025 05:24:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=113411&PID=200611&title=b450-itx#200611
