Just built my pc, cant get past q-code 54 "unspecified memory initialization error" 

 

checked the cpu, no best pins etc.

re seated the ram and gpu

check/ reseated 8 & 24 pin everything seems fine

 

everything is brand new except gpu which  a friend has loaned me and said was working fine.

 

system:

Mobo: crosshair hero 8

cpu: ryzen 5600x

gpu: asus rog 1070

ram: Corsair vengance pro rgb 32gb 3200mhz cl16

 

memory express did flash a new bios onto the board when i picked it up, wondering if i should clear CMOS and re-install a bios?

Start with clearing CMOS

okay so i pushed and held the clear cmos button on back of mobo for 10 seconds (with power off, is this right)

 

switched on and same thing, everything lights up, case and aio fans spinning, 

 

gpu lights up, fans spin up but then stop, getting nothing out to my monitor from DP or HDMI

okay so after clearing cmos i downloaded the latest bios and flashed it and its booted into bios now
