Lenovo Thinkpad X390 Yoga - Razer Core X TB3 not working

Hi,

 

I've been trying for a while to get my Razer Core X working with my Lenovo Thinkpad X390 Yoga but nothing that I have tried has worked.

I've tried updating the Thunderbolt firmware, Thunderbolt driver and BIOS of the the laptop but when I plug in my Razer Core, I get the windows "Limited Functionality" popup and nothing showing up in the Thunderbolt Control Center.

I've tested the Razer Core X + RX 5700 XT GPU on my older Lenovo Thinkpad and it worked straight away so I know it must be something to do with the laptop and not the GPU or Razer Core X. However, the older laptop uses Thunderbolt Software and the newer one has Thunderbolt Control Center. I haven't been able to install the Thunderbolt Software though as it seems that is no longer used?

 

The Lenovo Thunderbolt FW updating tool and driver that I installed are located here:

https://pcsupport.lenovo.com/gb/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x390-yoga/downloads/DS541974

Any help would be greatly appreciated.

@michaeljg, Have you accessed the BIOS and check for Thunderbolt settings? If possible, change the security settings to No Security.

@itsage Thanks, I changed the BIOS Thunderbolt security setting to No Security. However, I uninstalled the Thunderbolt Control Center while trying to reinstall all the drivers/etc and now i can't reinstall the Thunderbolt Control Center. The MS app store is disabled and I have no way of enabling it so I can't see how I can get this working now. I'm just going to use my old laptop and live with the slightly lower FPS

@michaeljg, The Thunderbolt device/component doesn't appear in Device Manager unless you have something connected to the laptop. I download the drivers manually then update it through Device Manager by right-clicking on the appropriate Thunderbolt device. Once the drivers are installed, the Microsoft Store will allow the install of Thunderbolt Control Center. Sometimes it happens automatically follow the install of Thunderbolt drivers.

@itsage, I've just tried again with no success, I've detailed exactly what I tried below:

From Lenovo's support page for the ThinkPad X390 Yoga, there is an article on Thunderbolt issues: https://pcsupport.lenovo.com/gb/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x390-yoga/solutions/HT508988

 

The article recommends that you install the Driver package and then the Firmware package. Thus, I installed the driver packager first ( https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x390-yoga/downloads/DS539550)

and then the firmware package ( https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x390-yoga/downloads/DS541974)

After the firmware is installed and my laptop reboots, I still don't have the Thunderball Control Center program.

Additionally, I've looked at this post here, https://egpu.io/forums/pc-setup/thunderbolt-control-center-vs-intel-thunderbolt-software/ and tried to follow along but I cannot see the "Thunderbolt" device anywhere in the Device Manager. I can see the "Core X" appear here:

I've tried to update it but I get a message saying that that the best driver is installed for the "Billboard Device".

There is a "Thunderbolt(TM) Controller - 15BF" entry but it has the latest driver that was installed above from Lenovo.

TLDR: Still don't have Thunderbolt Control Center

@michaeljg, It seems the system can only see the Razer Core X as a USB-C device. Do you have another Thunderbolt 3 cable to try?
