The Asus Pro WS X570-ACE is supposed to allow me to run 3 cards in x8x8x8 mode, but I’m yet to get all 3 cards working together properly.
I have three RTX3060 video cards (ea PCIE 4.0 compatible) plugged directly into this motherboard. All three are showing up in Device Manager and working “normally”, however GPU #3 has error code 43 in Device Manager.
What’s even more puzzling is if I remove the GPU #3 that’s plugged into PCIE3…then GPU #2 in the PCIE2 stops working and gives code 43 in device manager as well"…very frustrating to use…seems like a hit or miss…
I used a Thermaltake PCIE 3.0 riser last night, with GPU #3 in the PCIE3 slot and it worked (finally) but at PCIE 3 x4 …instead of x8, but after trying to troubleshoot this, it is back to not working again.
My specs are below:
Motherboard: Pro WS X570-ACE
CPU: Ryzen 7 3700X (3rd Gen)
OS: Windows 10
GPU: 3 x Zotac RTX 3060 (Non-Ti)
I’m at a loss, the GPUs have all been tested and work on one of my older boards without issue. Please help if you can.
