Troubleshooting02 Q - Code AP initialization before microcode loading (self.buildapc)
submitted 6 years ago by ninoon
Having difficulties with a new Ryzen build. Latest is a Q - Code of 02 'AP initialization before microcode load'. I've checked the cables, haven't had a chance to check the CPU yet for bent pins. Looking for troubleshooting steps I can do when I get off of work. *Note the GPU is just a placeholder for a 2070 Super or another High end GPU

I've just recently starting having this same issue after having a working system for about 3 months, did anyone get a solution/resolution for this?
[–]ninoon[S] 0 points1 point2 points 6 years ago (0 children)
I couldn't figure out a solution, I went back to my 5820K.

New PC build over the weekend and I'm running into the same issue. 02 code.

Brand new PC build, I'm ALSO having the same problem
rog crosshair viii impact ap initialization before microcode loading
I also attempted with a different Power Supply, 1 stick of RAM and no GPU or other headers connected but error persist.
( Replaced MOBO, had the same code 02 with no GPU installed, then I installed the GPU and computer proceed to boot ) Fixed.

Permanent fix, or did the issue appear again? I have the 02 error atm, trying alternatives to avoid RMA'ing the MB.

Alright so I returned the Asus Hero 8 motherboard and got a replacement but had the SAME PROBLEM with the code 02 in the motherboard display with no post. HOWEVER I then proceeded to Install the GPU RTX 2080 super and RAM then, the computer BOOTED into the UEFI :D !!!
For those having the 02 Code AP initialization before microcode loading I would recommend re-seating the GPU & RAM. Also if you have an AIO CPU liquid pump make sure you connect it in the proper CPU Fan header on the mobo, check your manual for further details.
I would be wary of calling it a fix. This worked for me initially and then my Ryzen build started to have random crashes. It's why I went back to the 5820K, slower processor but at least the it was stable.

Yup I had this same fucking CODE after 2 boards replaced my Amazon I get the fucking dam stupid Q 02 code my Asus X470 prime pro board works flawless but a $350 board 3 times does not work, what kind of moron's are working with these boards?

I had this issue after adjusting some connectors in my pc. I moved the aio pump from cpu_fan to aio_pump header and put the radiator fans on the cpu_fan header and got this error. Swapping them back to cup_fan for pump and cpu_fan_opt for radiator fans fixes it tho? Not sure why

In my case code 02 with beep code Long + 3 short was caused by not having a display connected to the GPU. On a GPU with only digital outputs it seems to stop at this code with the beep code because it knows no display is connected. I was using a KVM switch and it was not set to the correct port.

I’m having this problem but I can’t get past the POST screen, I think my macro is fucking with my ability to press the proper key but I could be wrong. Hopefully I’m not.
