Sorry for the late reply, I'm not as active as I used to be on here. I used a normal hdmi cable and a hdmi to DisplayPort cable that I found on amazon. Hope this answered your question.
I have not had any problems with the ram. To be honest, I chose the red Trident Z's because of the aesthetics haha
Updated the PC with a MSI 1070 and got rid of 1 of the SSD's since it wasn't being used. The new keyboard and mouse was much needed. No more cheap peripherals! Also painted my room :D
