POST CODE 7A

[theqtguy]

Recently, I just got my pc done and upon turning it on, it didn't boot into bios for the first time. So I updated the bios and it booted. Installed windows, updated and benchmarked. I was trying to ramp up my mem speeds thru DOCP, however, I just can't get a boot. So I managed to keep it at 3466Mhz with timings 18-20-20-20-40 1.35V. It did work... for 9 hours until it just hung and won't boot again. It's stuck at a post code error 7A. I have already reseated my ram and cpu just like in the forums. I also cleared my CMOS and reflash BIOS but still didn't work. Any suggestions? 
 

Specs:
Ryzen 3700x
X470 Asus ROG Crosshair VII WiFi 

16x2 Corsair CMW32GX4M2Z3600C18 Memory

People are saying a new mobo is the solution. Try resetting the bios and boot up to windows. Restart and try it again.

EDIT: Shit. Saw that you cleared your CMOS. But try again and reboot and then OC again.

I've flashed bios for a couple of times already and still :((

However, if I turn on the pc for 30mins and press the reset button, the code changes from 7A to code 55. Which means memory not installed.

Hmm. Have you tried running the RAM in different slots? I am not sure why it would do this other than that the motherboard is bust.

Yeah. Definitely a mobo issue.

Could also be the RAM itself. Try with different RAM and see if the issue still occurs.

Yup I did. From single channel to dual channel. If motherboard is the prob, what motherboard do you suggest buying for replacement?"

Any mobo would do as long as it passes your standards haha

The Gigabyte B550 Aorus pro AX would be good. Not very expensive or cheap. Kinda in the middle. Very good boards for the price.

Nice! Thanks for the help!

anything above 3200 is not guaranteed to run on that CPU

 

try enabling DOCP but set speed to 3200

 

or maybe see if the RAM DOCP profile has 3200 MHz, some of them have 2 profiles

 

check ram stability with memtest86

He has tried switching to other speeds and tried a new RAM set. The motherboard has to be the issue here.

i didnt see him run below 3200mhz, which is AMD's official spec (even then, it might not be stable but the chance is low)

Yes. Even reflashing bios. Probably did it 10+ times already T_T

then im out of ideas, could probably try a new board, but im not entirely sure that's the issue
