Ok, so that card takes one 8 pin PCI/PEG connector and one 6 pin PCI/PEG connector. So yes, you will use one 8 pin or 6+2 pin connector and then only the six pin portion of the other 6+2 pin connector leaving the two additional pins off to the side not plugged into anything.
Just wanted to make sure you had the connections right.
What is the exact model of your memory kit? If you don't know, you can download CPU-Z, install it, run it, look on the SPD tab and choose one of the DIMM slots from the drop down menu in the top left corner and then find the part or model number from the information populated in the fields below that.
Also, look to see if it says it is running in dual channel or not?
Your memory modules should be installed in DIMM slots that are located in the 2nd and 4th positions over from the CPU. If they are not, then they are not installed correctly.
Also, look on the memory tab in CPU-Z to see what SPEED the memory is actually running at. It will show up as HALF of the actual speed, because DDR memory is Double Data Rate. So 3000mhz memory will show up as 1500mhz in CPU-Z on the memory or SPD information.
On Ryzen, if the memory is not running at it's optimal capability it can have a seriously detrimental effect on performance.
Have you done a CLEAN install of the AMD drivers using the DDU? If you have not, I would highly recommend that you do so. You will want to FIRST run it and choose the Nvidia option. And then after that process completes and you are back in Windows again, run it again and choose the AMD option. Prior to doing either of those things though, be sure to download the latest AMD graphics drivers for your card model.
