ROG Maximums VIII RANGER frozen post!

[Mystikalrush]

I recently got this board with a 6700K, which works flawlessly, and XMP 3000MHz ram, which works as advertised, while using the latest 1601 BIOS.

To begin, i have been having a lot of headaches with this board, and am starting to wish i stayed with my previous trusted board partner.
Posting, takes forever! Luckly i was able to solve this problem, partially by setting up UEFI booting, since i RAID 0 my SSDs.
This post would do the following. 8-10seconds ROG bios logo -> Display my raid array drives and info, 5 seconds, -> revert back to ROG logo, AGAIN 8-10 seconds...then it would reboot... and re-do the ENTIRE process again! To which it would finally load windows, after doing this process, literally taking almost 1 minute to finally see the Windows logo on screen. And, yes Fast boot is enabled with 0 second delay time.

This was very odd and frustrating, but like i said, i was able to partially solve this by correctly installing Windows 10, via UEFI which now only displays the ROG logo for about 8-10 seconds and boots into Windows 10.
However, as my previous boot process would do this very strange reboot step throughout posting, it seems my UEFI boot wants to do the same, so every time i restart my pc within windows, it boots to the ROG logo and stays stuck in that screen, unless i manually hit my reset button on my case, to which it will boot and load into windows. But still, i shouldnt have to always be worried or concerned that my PC correctly restarted and isnt stuck at the BIOs logo screen.

So, what gives? Why is this happening? Why does the logo still hang while i have a 0 second delay? Is this common among ROG boards? Is there a setting im missing in the bios? Please help!

**EDIT** Solution solved, with 1 burden in reply.

Hello Mystikalrush

Welcome to the ROG forum !

Try this: On the boot tab set CSM to UEFI, disable boot from UEFI from pcie devices, enable all other UEFI and UEFI driver only, this should help speed up the boot process.

Please report back if this helps.

In my Maximus VIII Ranger BIOS, the only "disable" option in that section is "Network devices" and I don't have the option to disable booting from PCI or PCIe devices. I do have the Legacy and UEFI options, but I can't disable any of the boot devices in this section except Network Devices.

Okay, so Ive self diagnosed a major flaw in this board, to which it has fixed ALL my issues. With a burden of one.

Apparently, unplugging all (2 USB) external USB 3.0 HDDs I have from my front headers has solved this issue. (also tested with them plugged into motherboard, with no difference)

This has fixed my Post logo hanging issue, and dramatically increased the boot time, it now sits at the logo for 3 seconds, to which i assume it is communicating with all plugged in devices first, then it boots. Nonetheless, this has fixed it dramatically and i no longer have long waiting time nor frozen post.

Sadly, this means i HAVE to keep my External HDDs unplugged when i want to reboot, otherwise the issue arrisses again. Which i really rather not have to manually keep plugging and unplugged my externals because i use them frequently. I've never experienced such behavior with a motherboard booting up. Any solution to fixing this problem? I disabled USB Legacy boot, which disabled the 2 drives in my bios, but this did not fix anything.

All right

I have the maximus viii formula and it seems our bios's are a little different, I had to go look to see how I have CSM set.

I have mine like this:

CSM (compatibility support module)

Launch CSM - Enabled
Boot Device Control - UEFI only
Boot from network devices - ignore
Boot from storage devices - UEFI driver first
Boot from pcie/pci expansion devices - UEFI driver first

I'm using a single OCZ Vector 256GB ssd, I fooled with this for a little while and these settings boot my pc the fastest, from the time I press the power button it takes 20 - 30 seconds until I'm in windows, DDR4 memory training takes a little longer than previous boards.

Since you did a UEFI install make sure "windows boot manager" is set as boot priority 1, I'm not sure if this affects raid or not I don't use raid.

Correct, it is set as priority 1, I have CSM Disabled, so it bypasses everything with quickness. I only sit at the logo for 3-5 seconds, and windows boots in less then 10. So less then 15 second from power is a massive improvement. I just wish i didnt have to keep my External HDDs unplugged for this to work.

It would be nice if this info could be passed to ASUS for possible bio update that would ignore any external HDDs plugged in that causes post to be delayed, or in my case even stay stuck at the post screen.

Well it seems you found the problem with your external HDD's, booting to windows in 10-15 seconds is fast.

You're on the latest bios so I'm not sure what else you can do to get your pc to boot fast with your external HDD's connected, I don't use those either.

You could check on the advanced tab, usb configuration and play with the xHCI setting, this may help but no guarantees. 🙂
