ASUS Rolls Out ThunderboltEX 4 Add-on Card
@dregpu, 5 of the pins look similar though - make an adapter!
I'm not using any of the pins and I get USB and DisplayPort alt mode with no modifications. Haven't tried Thunderbolt though.
Here's a Thunderbolt 4 video from a guy who's done many Thunderbolt add-in card videos before.
The motherboard manuals have the pinouts.
ASUS ThunderboltEx 4
Gigabyte GC-MAPLE RIDGE
Asrock Thunderbolt 4 AIC
Has anyone attempted to use this card on non-Asus boards? I don't have a tb_header but I've read that pins can be shorted to fool the card into thinking it's connected, but that seems to apply to different brand cards. I'm not able to find any reports of anyone shorting pins on the 14-1 pin Asus version.
@elclamo The shorting of the pins on TB cards is mainly just an electrical signal to power on the card. Otherwise, they stay off for some stupid reason. The other leads don't seem to be crucial, although perhaps useful for some motherboards regarding how the allocate resources on bootup. I'm hopeful the Asrock TB4 card will work without the mobo header because there are separate jumpers for force power and RTD3. Just a guess though.
@elclamo, I'm using the ASUS Thunderbolt EX 4 in a Mac Pro 2008. Currently just for USB 3.1 gen 2 and DisplayPort Alt Mode. I don't have to short pins for that like I do for a GC-TITAN RIDGE or GC-ALPINE RIDGE. Not sure about Thunderbolt support though. I haven't gotten around to it.
