Computer won't post

[egriff79]

I just upgraded from a 5800x3d to an 7800x3d and it's not posting. The motherboard is a asus b650m-a csm 32gb ddr5 g.skill trident 6000 cl30 38 38 96 with a rx7900xt. I upgraded the bios I reconnected mb power cpu power reseated ram. Also reinstalled the cpu. 

 

When I turn it on everything lights up my fans gpu and ram (ram lights up a couple seconds after everything else. My guess is bad cpu if there's anything I might of miss or have an idea much thanks. 

 

AND HAPPY HOLLIDAYS

Did you let it try to post for a solid five minutes or so? Zen 5 4 takes forever to memory train on the first boot.

Yeah for 20 mind and nothing. I do remember some am4 build I did it took forever to post like you said I was about to say it was broken then all of a sudden posted that's what I was hopping with this.

Well there are a couple of options to try. You could try booting with only a single stick [of memory] in the farthest slot from the CPU. You could also try using the motherboard's BIOS flashback feature to flash the latest bios.

have you rebuilt outside of case and just used the minimum for it to boot, even no drives 

 

make sure cooler not to tight or to lose

 

try 1 stick of ram in each slot

 

no bent pins in socket?

 

all cables fully connected both ends psu/mobo

Already did the bios flashback tried every ram spot but just the furthest one will give that a shot

Got it working with one ram stick in furthest from cpu and it finally posted then put the other stick in still works but for some reason it's running dog slow instead of gaining 10-20 % more fast I am getting the opposite it's much slower then my 5800x3d
