ASRock Z77 Extreme4 Dr. Debug 4F

[jmodels]

Hello,

I am currently testing my new motherboard out of the case like I normally do with new builds. At the moment I have the PSU connected with the CPU and one stick of RAM installed in the correct slot (B2). I am going from onboard video VGA to my monitor.

The problem is when I try to boot error code 4F is displayed and then the machine shuts down. According to Dr.Debug in the manual the error means 'DXE IPL is started' but after googleing I have found nothing. I get no video display or anything. The machine does not reach the BIOS. At the moment all I can do is mess with the components but I'm stuck.

What is also strange is the board very rarely displays the error code 55 which means memory not installed but after trying many different sticks I don't see how this could be the issue.

Any ideas?

Thanks.

Hi, What CPU using?

 

[jmodels]

Intel i3-3470

The CPU requires the 1.40 BIOS version (there should be a sticker on the BIOS chip with the board's BIOS version).
Is there a problem with the CPU fan (not spinning) as I can't see well in the video?

I will check the BIOS ship now. And no the CPU fan appears to spin correctly. It spins at least.

The movie was moving real fast but I think you have the wrong power plug in the mb pci power port. There should been a black eight pin cable or two for pin cables for that plug. On mst new mb there have the 24 pin cable plus four pin white cable next to each other.

I believe this is the BIOS chip. Its user replaceable.



If this is the BIOS then it is version 1.80? In which case the CPU should work unless the previous user of this board has bricked it during an update.

Yes, the BIOS does support the CPU. So it's not a new board. Then it might be a board issue.
You can try ordering a BIOS chip and replacing the board's one (it's on socket, I think), but I'm not sure it's a BIOS problem.

Fault was caused by a broken CPU. See thread: http://www.pchelpforum.com/xf/threads/asrock-z77-extreme4-dr-debug-error-4f.151837/
