Hey Friends! I've had my Razer Core for about a year now. The setup is: Razer Blade 2016 [B4T/W10/QHD+/512GB/GTX970] Razer Core EVGA GeForce GTX 1070 FTW GAMING ACX 3.0 Windows 10 Creator's Update (build 15063.138, version 1703) It's been both great and a bit painful at the same time. I'm not starting this thread to debate if one should buy or not or if the new Blade with the GTX 1060 is better or even benchmark stuff. No, this is for those of us who have the Razer Core and those who will. Below are some troubleshooting, configurations and some obscure nuances that I have run into as user / developer and thought I'd share them with you. I'd definitely encourage anyone else who has run into things to share them here - It might help @Razer|Technokat and others build out a solid FAQ for Core users. In no particular order... I just updated Windows 10 to the latest build and Thunderbolt software recognizes my Core but Windows does not see my video card. Solution: Definitely not elegant but recent Windows updates have caused many hickups with external GPUs Uninstall your video card drivers Reboot windows Install the latest video card driver Prevention: Try installing Windows updates with the Core disconnected. Thunderbolt software does not recognize my Core on Windows. Solution: This one is a classic try this then that. Sometimes power surges happen, config changes so on. The following has worked for me... Unplug the Core and wait a minute then plug it back in. Sometimes just discharging the capacitors seems to help get things working well. Or.. Unplug the Core from your PC Unplug the Core from your PC Shut down completely Plug the Core back into your PC Turn on your PC Or... Unplug all of the devices from your Core. Sometimes a rogue device can cause the core to not do what it needs to do. Unplug all of the devices from your Core except for the PC Reboot the PC Plug each device back in to find the flawed component The Razer Core does not power on Solution: This was a 2-parter for me. Turns out that the video card can come unseated as you push it in because of the latch inside the core that holds the tray in - as you push it in the power cables going to your video card can get hung up on it. Also, if the card is not pushed all of the way in the Core will not power up. A good way to test this is to try to pull out the tray while the handle on the back of the core is lying flat on the back or closed; if the tray comes out the Core is not properly closed. The Core does not lock when I close the latch on the back Solution: There is a little latch at the top of the Core body about an inch from the back. Mine fell out day one. It almost feels like it is magnetic - it's a really small part and it seems to fit snuggly in the hole in the top of the Core body. As you push the tray in with your video card the power connectors might pull this latch out of place. Make sure this latch is in it's place as the part is metal and could possibly short your video card if it falls down into the tray. Just like above, a good way to test this is to try to pull out the tray while the handle on the back of the core is lying flat on the back or closed; if the tray comes out the Core is not properly closed. My Video Card fits but the when the power cords are plugged in the card does not slide in Solution: Pay close attention to the dimensions (GPU Max Dimensions: 12.20” x 5.98” x 1.73” (310 x 152 x 44 mm)) if you are about to buy one of these and you want to use your favorite card. Allow a few mm for height if your power plugs into the top of the card and a few mm in depth if your power plugs into the front of the card. Optionally, you can get all types of cable adapters and right angle adapters that will help keep your connections from interfering with card placement.
