I tried it yesterday with my friend's Corsair Vengeance RAM sticks. It is a kit of 2x 32GB sticks. Same behavior. Unfortunately he didn't have any other RAM sticks. I could buy a 2x16 GB kit, but I would like to know for sure that it is the RAM or else I would be throwing out money for nothing...
Thanks for the reply! I understand that a 2x kit has better performance. My idea was to buy another 32GB stick later on. This is my first build, so I made a mistake here. I will borrow a RAM stick from a friend today to try out.
I wanted to assemble a pc for Christmas but it is not booting and not giving any beeps. I'm getting desperate, having spent weeks trying to figure out the problem, so I decided to post here I hope that somebody can help me diagnose the problem. I will try to write down all the information...
