Switching "Power Supply Idle Control" to "typical" seems to do the trick. This should not be necessary with such a mature architecture but I guess it is.Could those be because of RAM issues? Have you used maybe testmem5 to confirm?
Post here with your issue.Can't go to BIOS/EUFI after flashing the latest BIOS? Anyone experiencing this as well? My pc just black screens whenever I press "delete" to get into the BIOS/UEFI. I just want to overclock my new Ryzen 5 5600x but can't. It boots into windows no problem though if I allow it.
Have you tried a bios reset using the jumper with the 3300x in?HI!
rx 5700 xt red devil
crucial ballistix 16gb kit (2 x 8GB) 3600
adata XPG core reactor 650w
also i have
b450 gaming plus max
The ryzen 3300x stuck on vga and boot leds, white lights steady on and no post, no beeps, no signal at monitor..
I change the cpu with ryzen 3400g on x570 tomahawk and works fine, i install 3300x on the other motherboard, b450 gaming plus max and works fine..
X570 tomahawk have the last bios 7C84v14.. i also tried all the versions of bios nothing, same results..
The b450 gaming plus max with 3400g cpu is from my brother's pc so i was lucky i could try different parts, all the combinations work perfect except tomahawk + 3300x
Very weird for me too, when i press the power button the debug led cpu light up for a sec and a fast blink for the rest of the leds, and then nothing lighting, cpu and vga fans spining and lights up.. that happens with the three first versions of bios..Very weird , i have X570 Tomahawk + 3300X and zero problems with any BIOS ( i have tested all of them )
