Please let me know how did you handle 8pin to barrel plus modification, it would be better if you share some photos thanks in advance.

Change Molex to barrel plug into 8pin to barrel plug might be a good idea for solving the instability issues, but I'm wondering if I can change CPU 8pin into barrel plug instead of PCIe 8pin as well?

Thanks for your response, I'll figure out how to use additional power on my GTX Titan, and good luck with your set. I'll keep update my work here if I successfully make my set work, I think it can help more people who are suffered by all these issues.

I've been thinking about that kind of power supply as well, could you tell me about how did you manage the 6pin and 8pin cable with that? I think you can only use one power sources to prevent GND loop right? Otherwise I can just simply switch my Molex to barrel plug to this 12V only power supply and use my original 850W power supply to power the gpu on the other side by 6pin and 8pin plug, sould I ?

But actually I have a 850W power supply, and the problem is still there, I would try to do the tricks you told me, fingers crossed

I have the same problem, you can try underclock your cpu a bit and do benchmark again to see if it would freeze or not, if it does just underclock a bit more.

I have almost the same setup with you, but there's some bottle neck issues. Hardware: Macbook Pro Retina Mid 2012 (thunderbolt 1) NVIDIA GTX Titan Akitio box 850W ATX PSU Softwares: OSX 10.11.5 Windows 10 pro (BIOS External USB 3.0 drive) WebDriver: latest Cuda Drivers: latest I've test a few times on Windows and OSX, I found that Windows system is more stable than OSX. When I try to do some benchmark such as Unigine Heaven or Valley, it just freeze after a few minutes, sometimes it can't not even reach the result and freeze, I wonder if it's because of the power supply of the PCI-e slot, but refers to what Nando told us https://www.techinferno.com/index.php?/forums/topic/5661-us189-akitio-thunder2-pcie-box-16gbps-tb2/&do=findComment&comment=115060 Other than Molex to barrel plug, there's no modification needed for the Akitio PCB board right? Does anyone know how to fix it?

Do I need to do PCI compaction every time when boot into windows? or I can just save the process and do it automatically every time?
