I'm getting error code 55, which is DRAM not detected/found. I bought new memory G-Skill DDR5 on the vendor list for my Z690-E Asus Board. And still getting the same error. So i'm pretty much going to rule out a memory issue. The CPU is a 12900K.
I'm thinking I fried the CPU on Motherboard by running the incorrect power to it. It calls for dual 8pin for the CPU and I used a 8 & 4pin connector instead. It worked for 5mins and then froze. Perhaps I fried the memory controller on the CPU? Perhaps I fried the motherboard? Who knows
