some news, I tested both GPUS alone, in the bios and Windows 10 without issue, so the motherboard is currently not SLI compliant. (ith my gpus) just asked for a refund. |

Dear Stef_day, Thank you for choosing ASRock. ASRock Z390 Taichi Ultimate
supports Supports NVIDIA® Quad SLI??and SLI?? Regarding your case, we also
test at our lab, after installing the NVIDIA driver, the SLI enabled
automatically. Please check the NVIDIA driver
SLI setting to check if the SLI is enabled or not.
Thank you! Yours truly, ASRock TSD |

" rel="nofollow - That's a really gorgeous build. Love the minimalist colors. :) Given the quality of the build I assume you didn't skimp on the PSU, just a thought though. BTW - where is your PSU? I can't see it? Is it external because you didn't have the space for it? And your coolant reservoir for that matter! Did you underestimate the size of your case, or were you always planning an external coolant/PSU build? Hopefully you just missed something obvious, but glad to see you actually got a response from AsRock tech support. I was pretty sure they were in hibernation for the winter. PS - is that a white colored coolant in your loop, or are they opaque white tubes? Never looked at XSPC before, but looks pretty sharp.
