NewXFX Radeon VII - No Post

Hi All,

Just picked up a Radeon VII brand new in the box non opened and PC wont post with it installed, cannot even see the bios screen just fast fan spin and then slow fan spin, reset CMOS & still not post, Motherboard bios is on latest version with CSM & UEFI enabled. PSU is Corsair AX 760i and has 2 8 pin connected to GPU.

Motherboard is ITX so cannot boot into windows with spare GPU to check if its detected or update the bios on it...

Any ideas ?

use your spare graphics card and then try again. I have to do this sometimes while testing.

Which motherboard are you using? Sometimes motherboard just bugs out and uses IGPU for no reason at all. I had a similar issue when during the Windows setup screen would go dark. Discrete GPU wasn't in use and the picture was coming from IGPU. Clear CMOS didn't do a thing. I manually selected discrete graphics in BIOS just because it was the only thing I haven't tried after 3 hours and it worked.

Did you try a different Display Port or HDMI connection on the Radeon card? Try all of them. Maybe one is dead, or the card is posting only to one output.

The only thing I can think of is to try Radeon on a different system. If it doesn't work there then it is dead.
