new build won't post

Brand new build including Asus ROG Strix B660-i, Asus approved G.Skill RAM (2x16), i5-13600k. It won't post. The yellow light on the mobo says a potential DRAM issue. If I remove the RAM then the beeps tell me the RAM is missing. Replace the RAM and the yellow light comes back on. I don't have parts to swap in and out without returning parts and ordering new. Suggestions?
