Are you using CSM?Can a new GPU throw off a memory OC?
I had my system running fine with a 1080 Ti and a 2080 Ti. After installing a 3080 with PCI-E 4, there was a boot error about the video card after the initial post boot. Upon returning to bios default or XMP profile, the beep went away.
I had to back down from 3733 CL14 to 3600 CL14. Any insight on this? The motherboard did bark at me stating that SOC over voltages can mess up a GEN 4 PCI-E. I'm assuming that the 3080 being PCI-E 4.0 has thrown this off?
