[Solved] Razer Core X and Radeon Vega 64 not working?
So I just got a Razer Core X and installed the Sapphire Radeon Vega 64 Nitro+ in it. When I turn it on nothing happens. No fans start spinning, my monitor isn't detected, the card isn't detected in the OS. Just completely silent and nothing happens at all.
Do you guys have a guess on what's wrong?
NB: I'm completely new here.
@mac_editor pretty sure but now you got me in doubt
Installed the card in the slot, put the 6+2 pins in and made sure the were all the way down, plugged in the power cord and used the Thunderbolt 3 cable that came with the Core X.
Is there something I had to be extra aware of when I installed the card into the Core X? Thinking about the 6+2 pins maybe?
@flax I don’t have a Core X but I’ve sometimes forgotten to turn on the switch (if any) on the box itself. Besides these minor oversights, you can check whether at least the enclosure is detected in macOS in About This Mac - System Report - Thunderbolt. Ideally fans should spin on connection. Hard to determine what, if anything, is defective unless each unit is tested with a known good configuration. People with the Core X may have better insight. Do you have access to another Mac by chance for testing?
Other things to try on your Mac: SMC and NVRAM reset. Might just do the trick, who knows.
Have you tried all TB3 ports on your MBP? My 2016 15” has had numerous problems with the right I/O cards and USB-C devices and display not working correctly (twice repaired by Apple already). I didn’t have an eGPU before I sent in my last repair, but I assume TB3 might have not worked correctly with the bad I/O card... just something you may want to check if you haven’t done so already. If you have a USB-C to HDMI out, you can possibly see if you have a similar MBP hardware issue if there’s no display out to your external monitor.
Thanks for the good suggestions both, much appreciated.
@mac_editor I've checked in system report with two MacBook Pro's 15" (2018 & 2016), sadly no Thunderbolt unit was detected in either of them. I've tried both with and without the Vega 64 installed. I've also tried to power it on via the power switch on the Razer Core X both with and without the Vega 64 installed, no luck either. The Core X fan is furthermore not spinning when powered on nor without the Vega 64 installed. I also tried the SMC and NVRAM reset without any luck.
I guess I'm out of options now and have to talk to Razer support about it. I assume that it's not the Sapphire Vega 64 Nitro+ that is the problem here. Unfortunately I don't have another setup that I can the try the Vega 64 out on.
So it seems that it is the Sapphire Radeon Vega 64 card that is the problem. It says that the card is supported for the Razer Core X on the website or have I overseen something with this specific card?
Could the Sapphire Radeon Vega 64 card be a DOA?
I've read that the PSU requirement for the card is 750W with the Razer Core X max output on 650W (500W dedicated to the GPU) but the Razer Core X should handle this fine or again am I missing something?
Hi i'm having issues with mine too - Razer Core X and Vega 56 - working 'fine'. but I've realised the internal Core X fan never spins. After approx 2-3 hours of intense use, the Vega fan goes into overdrive and then restarts, cutting the monitor and causing issues with Windows. If I restart everything works again, but it's clear the fans should be spinning and it's causing some sort of heat issue.
Out of interest how did you solve your very tight 6+2 pins problem? wonder if I've done something similar?
It turned out, that the problem was the very tight 6+2 pins that caused the problem. Everything works great now!
Hi @flax Could you elaborate on that? I have a similar problem at the moment and can't find a solution. Did you just unplug the pin power connectors a little bit?
