eGPU Support Issue

[egpuIssue]

I cannot get my Razer Core X to work with my HP spectre x360. 

When I plug in the Razer Core X it shows up in the USB4 Hubs and Devices with the bandwidth 40Gbps/40Gbps (Gen 3, dual lane). I do not, however, see anything in the display adapters and I cannot get it to recognize the GPU. The GPU has been validated as good (and another has been tried), the cord is Thunderbolt 4, all drivers have been updated including bios, and both thunderbolt ports have been tried. There were suggestions online to look for security settings disabling pcie tunneling however I do not see anything in the incredibly barebones BIOS settings that would be useful.

Any suggestions on how to get this working or if there is something preventing my laptop from working with a eGPU that would be great to know.  Thanks.

Hi @egpuIssue 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for the all details.

You’ve already done most of the right checks (cable, BIOS, GPU validation, drivers). The tricky part is that HP Spectre x360 models, while having Thunderbolt 3/4 ports, do not always support eGPU functionality, because OEMs can restrict PCIe tunneling at the firmware level. That explains why the Razer Core X enclosure is seen as a Thunderbolt device but the GPU inside isn’t enumerated under “Display adapters.”

Things to Try

1. Confirm Thunderbolt Security Settings

Open Intel Thunderbolt Control Center (or “Thunderbolt Software” on older systems).

See if the Razer Core X shows up.

If it does → make sure it’s “Always Connect” / “Approved.”

If it does not → that usually means PCIe tunneling is blocked.

2. BIOS Settings (limited on HP Spectre)

HP’s consumer laptops often hide advanced BIOS options.

Check if there’s anything under Security → Thunderbolt Security or Advanced → PCIe settings.

Unfortunately, many Spectre x360 BIOS builds don’t expose these at all.

3. Driver Check

Update to the latest Intel Thunderbolt drivers (not just what HP Support Assistant gives you, but directly from Intel’s site if possible).

Update to the latest GPU drivers (NVIDIA/AMD depending on your card).

4. Test with External Monitor

Sometimes, even if the laptop doesn’t register the eGPU in Device Manager, plugging an external display into the GPU’s HDMI/DP output will confirm if tunneling works.

5. Limitations of HP Spectre x360

Unfortunately, many HP Spectre x360 models (including 2020–2022 ones) do not officially support eGPUs. HP locks down the Thunderbolt implementation so the enclosure is recognized, but the GPU inside never initializes.

Bottom Line

If Thunderbolt Control Center shows the enclosure but not the GPU, and no BIOS options exist for PCIe tunneling, your Spectre x360 may simply not support eGPU use.

Workarounds (like modified firmware) aren’t safe or officially available for HP systems.

If your goal is to use desktop-class graphics, you may need a laptop line that explicitly supports eGPUs.
