Yeah i only hard shutdown but once in a while, the next boot does that. Guess its a "normal" behavior then

zbug Any of you using this board + 3900x sometimes will get all fans, rbg etc on boot but the screen stays black and nothing happens? hard power off and power on again and it boots just normal. I get this like once every 20+ reboots maybe (first time in 1 month today)

rdr09 Just noticed 6 of the 8 cores on my R7 2700 are boosting to 4.1GHz (highest boost at stock) at idle using BIOS 5406 and Win10 1909.

p4block I fixed it.

Found the flashing port pinout on a forum thread, posted by elmor on the rog forum.

Trimmed out the first 4 kilobytes of the bios on the website and got the true rom file. Flashed it using a lot of cable clamps. On my old Z97-AR it would've been much easier, just pull out the chip as it was socketed.

Original serial number has been lost, could probably restore it with afuefi but I frankly don't care. Ethernet mac address is not stored with the chip unlike on intel platforms, so I didn't lose the mac address.

Overall a pretty simple fix if you have the proper information, which ASUS won't give you given their systemic "user is an idiot" policy.

The weird thing is that CrashFree3 doesn't seem to even look for files in the drives, it's just blinking the cursor.

It could very well be in a broken state, thinking it has a 32MB bios while having a 16MB one, and not being able to flash neither.

I have an external programmer, my only issue is that the pinout for the flashing port on this board is a bit unknown. I found it on a random forum but I don't want to risk it 100%

p4block So, this board had weird issues for a while (no resume from suspend, broken boot entries in linux) and overall weird behavior. I tried to fix it by mass flashing newer/old bioses and seeing if it worked.

It pretty much did not. I started getting annoyed and flashed a 32MB bios's nvram partition (latest bios) while being on an older, 16MB bios. Mostly because afuefi is broken on this board and the bios appears to be 16MB even though the CAPs are 32... anyway.

That caused this beautiful CrashFree3 recovery screen:

I looked around and found little to no info on how it actually works. ASUS support was not helpful at all and just linked generic instructions that I would bet were written in 1998.

Eventually I found a video from a guy with an ASUS B350 whatever and he got it to work by putting the usb on a specific port and using a specific bios version.

The only issue is that it doesn't recognize any BIOS file, on USB drive, on any port, the bios in DVD drive or even the BIOS on an HDD. I've tried literally everything (100+ permutations or something like that) and it just hangs on that flashing cursor.

A fun fact is that having a nvme drive in the first slot will cause the screen to get corrupted.

Has anyone ever got this to work on this board?

gasolin oced i can get 4.1ghz but stock it's only 3.95ghz ish on all cores

Stock mine goes all the way up to 1.352 volt

1.325v is most that's pushed under PBO. Best all core OC is 4.35GHz and for that it already needs 1.4v and temp can hit 78c under prolonged full load prime 95 small fft. or OCCT. I don't use it OC-ed much so it's not a problem with temps even over 80c. Low temps, about 62 - 65c are important only for PBO to function properly.
