Hi,

Can anyone help? I installed a new Gigabyte Geforce RTX 3060 Gaming OC 12 GB R2 graphic card in a Razer Core X eGPU, but it was not been detected on my Dell XPS 9270 laptop running Windows 11 Pro. I also installed the latest graphic driver from Nvidea: 537.58-desktop-win10-win11-64bit-international-dch-whql, but the graphic was still not detected in the Device Manager and the Thunderbolt Control Centre did not pop up or display the Port.

The Razer.com website states that “Yes. Thunderbolt 4 devices should support eGPU devices like the Razer Core X and Razer Core X Chroma. As Thunderbolt 4 is backwards compatible with Thunderbolt 3 and encompasses the requirements and capabilities of the older protocol”, and that “There are two current versions of the Thunderbolt 3 controller:

• Alpine Ridge
• Titan Ridge

Both the Razer Core X and Razer Core X Chroma use the Alpine Ridge version which is technically the older controller version of the Thunderbolt 3. However, being the older controller does not make it any less. In fact, it has the same bandwidth as its newer kind, the Titan Ridge. Both versions feature a max speed of 40 Gbit/s.

Also, Alpine Ridge is what is recommended by Intel’s Thunderbolt team to be used by OEMs in their eGPUs like the Razer Core.

Using the Titan Ridge will not give any benefit to Razer’s eGPUs, it is more likely for the host system (Laptop side) and other Thunderbolt devices.”

However, as Thunderbolt 4 uses the Intel JHL8440 Thunderbolt 4 Goshen Ridge Chipset Controller, is it a Razer Core X eGPU compatible with a laptop that has a Thunderbolt 4 or not?

Thanks,

Peter
