Arc Pro B70 day 1 drivers dont appear to be working

phillipcarroll — Tue, 31 Mar 2026 20:25:24 GMT

Received an intel branded B70 today. Running gfx_win_101.8515 drivers. Any application that uses graphics, ie video editing or games it will crash and then eventually my computer will crash. This is a fresh Windows 11 install, Asus x870e ROG Strix MB. Core 7 270k plus.

Is there a secret day1 driver I should be looking at?

The gaming driver wont install, hardware is unsupported message pops up.

Reinstalled drivers several timed using DDU, same issue, when the pc crashes it shows an IRQ error

Reseated the card, still crashes

Forced the GPU to run at x8 pcie 4.0 and so far its stable. But that seems like I should not have to do that.

Played around some more, it would appear the pcie 5.0 negotiation is not function, so this could be specific to my motherboard/firmware. But the B70 will not negotiate 5.0, after moving to 4.0 x8 everything works great, amazing speed. But now it wont even let me set it to pcie 5.0 so I assume some communication between the MB and the GPU is not advertising that it can reach pcie 5.0.

Just random crashing from windows, sometimes just idling. dxg failures, irq conflicts, kernel panics from traps. So either I have a bad GPU or simply there is some driver conflict/issue.

DDU/Reinstalled the driver several times.

Turns out this was a bad 8pin adapter, must have been pulling down voltage. Fixed, day1 drivers are fine. performance is excellent. I am stupids.
