I believe Intel 12/13/14th gen allows 8x/8x, but no 4x.

There is no info on bifurcation in the manual for my board either. The options in BIOS are present.]]> Fri, 21 Jun 2024 03:39:51 +0000 https://forum.asrock.com/forum_posts.asp?TID=42714&PID=127198&title=pcie-bifurcation-on-z790-pgitx-tb4pound#127198 https://forum.asrock.com/forum_posts.asp?TID=42714&PID=125384&title=pcie-bifurcation-on-z790-pgitx-tb4pound#125384 Author: MsNIKITA

Hi there.

More of a pre-purchase question.

Does anyone know, does Z790 PG-ITX/TB4 support PCIe bifurcation? I have been looking at the product page and manual but can't find anything mentioned

Essentually I would like to split the x16 slot into two x8 slots for supporting two seperate PCIe cards.

Thank you. ]]> Tue, 11 Jun 2024 13:03:50 +0000 https://forum.asrock.com/forum_posts.asp?TID=42714&PID=125384&title=pcie-bifurcation-on-z790-pgitx-tb4pound#125384
