Have a barebones test setup as I prepare to salvage my old PC for this upgrade: MSI B650 Tomahawk board, amd 9800x3d with a noctua nh-d15 cooler mounted (and pasted), and so far I've tried one kit of Corsair Vengeance ddr5 6000 cl30 (both individual sticks and pairs in different slots and orders) and I've begun trying a kit of G.Skill Trident but so far having tried them only as a pair I get the same result, orange debug light.
I have flashed BIOS to the latest version via USB stick, the two times I did both times appeared successful.
I fear that I might have left a trace cotton fiber or two on the socket from attempting to clean my cpu socket of my finger grease (after I accidentally brushed it when dropping the cpu in) or that I might have bent a pin unintentionally when I tried to clean the grease with an alcohol pad on because I didn't realize that the pins would grab on like velcro immediately. I visually inspectd them the best I could before seating the CPU and they appeared uniform but maybe i missed a bit of cotton fiber debris. I can include a video I took of the socket before seating the CPU if anyone wants to take a look. I can try recording another video using a better quality iphone camera since my phone sucks
note: When I attempt to post, there is no GPU or anything else plugged in but my psu cable, keyboard and a display port cable to my monitor. (not sure if I need to be using HDMI or Display Port specifically to see post or if I need a USB 2.0 keyboard to see a post screen but my only kb is usb 3 and my monitors are DP and DVI only, I have an old VGA monitor with an hdmi adaptor as well not sure if they'll show post though). (I have the two pin 8 pin cpu headers plugged in, and the 24 pin as well.)
