Blank screen after setting 4g decoding in bios
« on: 26-January-18, 18:43:51 »

After flashing bios to v5.5 on X370 Gaming Plus board, I was able to get into bios setup and change vga settings to 4g decoding enabled. However now machine just boots into black screen. I never see the bios screen or even windows it's just black. Hitting del key repeatedly does nothing.

Note before making the bios change I was able to boot into windows, although only one of my cards showed--which is why I was trying to tweak the bios settings. I did not change the pci gen settings as I could not find them.

Configuration:
X370 Gaming Plus
3 x EVGA 1080TI with matching risers
Ryzen 5
2 x 1000w power supplies

How do you expect any help when you don'd even say what motherboard you have?

I'm getting nearly the same issue on this board. If I enable 4g decoding I can boot into the OS (Linux) fine, but if I press DEL when booting up it gives me a black screen and I'm not able to get back into the BIOS to change any settings without resetting the CMOS.

Another issue - I'm able to get any of my 5 GPUs up and running no problems (with or without 4g enabled), but as soon as I add the 6th GPU it gives me an ez debug vga led light on the mobo. I have all GPUs except one on risers.

Any help is appreciated!

I think the bios is pretty the same, so try this:

during boot keep pressing DELETE to get into bios. even if you get a black screen, you are basically still in bios.
press F6 for loading optimized defaults, press enter, then press F10 to save and exit, and enter.

Should work for sure.

Hello,
Doing a clear CMOS should work.
Of course, it will not resolve your 4g decoding need but permit to "see" bios setup then Windows on one of the 3 GPU. Then, I suggest you to return to try to M-Flash again the new bios version.
Good luck,
:-)

Hi guys,

I had tried to clear the CMOS already using a jumper and by removing the battery, but this didn't seem to work at all.

Doing what Papatya said did the trick to clear the CMOS and now I can at least get back into the BIOS when needed. Press Del when booting and then press F6 for loading optimized defaults, press enter, then press F10 to save and exit, and enter.

You're the man Papatya, thank you!

I'll try the re-flash to see if it helps with my 6 GPU problem.

The issue will be fixed in future BIOS update
if your issue is urgent, then Enable UEFI Boot Mode
and should works fine.
