X570 Crosshair VIII Hero won't post to bios!

[jakesterdog123]

Have an x570 Crosshair Hero VIII wifi motherboard, was working fine but suddenly doesn't post to bios at all. Using 5700xt gpu and Ryzen 3900x cpu. Please help, this is the second board I've had this sort of issue with. I tried reseating all components, cmos resets, moving ram around, using different ports for hdmi or displayport. Nothing displays to monitors. Tried unplugging monitors as well. Please help!

pull this out 'Xonar Essence STX' completely and see if it boots.

clear your CMOS to bring back your system default

to start bios you have to unplug all USB connection and storage just plug the keyboard will do do trick

Finally got it working i tried booting with JUST GPU and the M.2 in took every thing else out and still 02 error.

It has some thing to do with the ram if i change it from (2133mhz) insta crash and i know for a fact the ram is good ive tried it in 2 other computers and zero issues and before i updated the bios i had no issues running it at 3600 so im going to guess its the BIOS (2206) ever since i flashed to it nothing but issues with ram .

so i got the MOBO to post with 3000Mhz at 1.4v which is insane with it suppose to be ran at 1.35 @ 3600Mhz

Make sure, the RAM is in Slots 2 & 4 from the CPU and then DOCP will work correctly to 3600.

Ditch this 'Xonar Essence STX' because it's never going to work just cause you grief.
