2013 Mac Pro (FP D300 x2) [3rd,4C,E] + RX Vega FE @ 16Gbps-TB2>TB3 (Razer Core X) + macOS 11.1 & Win10 20H2
I didn’t saw the detail on the two lower TB. So this is the story: I read in a forum that it was not recommended to connect the eGPU to the TB2 I mi distes on top of the HDMI because they share bus interfase and will be detrimental to the video quality. Plus I ran techpowerup and the bus interface was running at x4 when it could be x16. Then everything went wrong and I had to end up reinstalling everything and connecting the eGPU in the lower right but still running at x4.
Again, thank you so much.
@anotheregpuser, hi there,
first off thank you for the post. It has been helpful but I’m struggling hard.
‘I was able to get my 6700xt running briefly but as soon as I started a game it stopped working and I haven’t been able to get it going since.
there are slight differences in the hardware we have;
I installed a 10_core cpu in my Mac pro
and of course my 6700xt.
‘at no point since have I been able to see the 6700xt in device manager.
question ; when installing boot cam- drivers should I be able to see the Gpu detected?
also in device manager after disabling the proper devices they become grey and I can’t re-enable them , any thoughts on why this is?
any help is greatly appreciated
I have an RTX 3060 which I generally use in an eGPU setup with an Intel NUC, which works perfectly.
I wanted to see if it would work with my old MacPro 2013 on Bootcamp Windows 10
Using the Thunderbolt 2 to 3 adaptor I was able to connect the MacPro 2013 with the eGPU setup (Sonnet Breakaway Box 550)
As expected it did not detect the eGPU. But after following the general build order for MacPro 2013, of disabling PCI devices on Device Manager i managed to detect the RTX 3060 but with error 12 (This device cannot find enough free resources that it can use).
Is there any way to fix this issue. Or, is using a Nvidia card with MacPro 2013 not possible.
Please share me your opinion. Thanks in advance.
I would like to share the experience and the problem that I am stuck with currently. If you have an opinion to fix the issue do let me know.
I updated the Windows 10 to Windows 11, and carried out the process of disabling the general PCI ports to detect eGPU. Following being the ports:
PCI bus 21, device 0, function 0
PCI Slot 4 (PCI bus 21, device 5, function 0)
PCI Slot 5 (PCI bus 21, device 6, function 0)
PCI bus 17, device 10, function 0
I rebooted system, and the Device Manager showed Microsoft Basic adapter. I installed the latest drivers. The drivers detected the card but reached the same error, error 12(This device cannot find enough free resources that it can use).
I rebooted system but only with the same error, error 12.
Additionally when I disabled the following port, PCI bus 17, device 9, function 0, and upon reboot, it the error 12 did not occur. The RTX 3060 detected along with the two AMD D300 cards (as seen in the picture below)
Although the three GPUs are detected in Device Manager, in Task Manager only two GPUs are detected
Also running GPU-Z shows the card but the GPU Clock and Memory are uninitiated (as zero)
Upon reboot or shutdown and startup, the situation remains the same.
Now, you are running a completely different setup, so it might not work, and maybe someone else is better to help you.
But, have you disconnected !everything! from the USB ports of the MacPro?
You can not have ANY devices connected during boot up.
A USB hub is also a device so that has to be disconnected too.
