According to the manual for your motherboard (that you never bothered to fuckin read) it is the code for "CPU DXE Initialization". Right on page 41, list of debug LED codes. RTFM people. Always RTFM.

B4 might not be an error, plug the monitor into a GPU maybe you don't have onboard graphics. Does unlock light turn on?

r/buildapc on Reddit: Error 64 with Gigabyte Z390 Auros Master

January 25, 2020 -

Hello all,

Just started building my first PC solo, and am having the above mentioned error. I can't seem to find a solution. I've tried swapping RAM, using 1 to 4 sticks, different slots. Currently I don't have a GPU installed, just trying to use on board video to make sure everything boots before installing the GPU.

All fans spin, cooler lights/powers up, no led's on the board are lit except the one indicating which bios is in use. The LED's for CPU, dram, VGA, and boot are all off which the manual states is correct and indicates they are working. I have tried removing the CMOS battery and resetting it to factory defaults.

Also, the Motherboard does not beep when booting, but I am not 100% sure it has onboard audio. My old PC did beep.

Not sure what else to try other then removing the cooler and CPU (I don't have thermal paste cleaner, so can't do that till i order some)

I appreciate any advice or help!

Thank you

That error seems to indicate something with the CPU (Page 131 in manual). That said, I'm not sure what to do to troubleshoot that. Also, the board will not boot unless you installed a motherboard speaker into it. Make sure you have all power hooked up. You've done the all the basic troubleshooting I can think of.

r/buildapc on Reddit: Z390 Aorus Ultra error code 64, can't get to BIOS screen

February 16, 2020 -

First time building a PC, got everything put together today but I can't get the BIOS screen to even show up. The error code I was getting at first was A6: "Detect and install all currently connected SCSI devices," but after switching the HDMI input from my MoBo to my GPU the error code switched to 64: "CPU DXE Initialization is started." Got stuck on both of these error codes and can't get BIOS screen to display either time.

Here's some things I've tried so far:

-Resetting CMOS

-Removing and reinstalling my SSD

-Removing my second graphics card and booting up with one

Any advice would be greatly appreciated!! Thanks in advance!

A quick Google: reseat your memory modules, or start by booting with 1, then 2 etc. Maybe look at the slots and see if they are in the correct ones. A1/B1 or maybe A1/A2 (quite confusing sometimes).

I don't know the error code but, the newer ryzen are often not supported in an old bios version. So try updating bios and see if that works.

Try updating the Bios using Q Flash Plus to newest version via USB (make sure to format it to FAT32 and renaming the update file to "GIGABYTE.bin"). In my case, the newset Bios version didn't work, but the previous version did. Seems to be happening a lot recently, not sure if it's quality control or something else.
