RVIE Post code error B4 Load VGA BIOS after new video card installed

[Mavtop]

Hey everybody,

I just removed my SLI 1080tis (because one card burned out) and put my old 1080ti back in (which works)
But now when I turn her back on the live dash is displaying error code B4 with the message “Load VGA BIOS”

Not sure what to do next...

I’ve tried clearing CMOS, no luck.
I read to try switching from display port cable to hdmi, and will try this tonight.

I’m looking for any other ways to get around this issue.

Anything helps.

Many thanks. *

Just some more info:
7980xe
R6E
Optane 900P boot drive in PCie slot 3
7TB of ssds
and DIMM.2 has 2 nvme drives in it.*
**Evga 1080ti ftw3 elite in PCie slot 1*

4K screen.

When I hit power button the system turns on, starts post and then freezes up with the Code B4, Load VGA BIOS. Error

I did just let it sit last night for about 30 minutes and it made it to the bios. But haven’t been able to get that far since.

Help me Raja! You are my only hope!

Tonight when I get home I will reset CMOS, try to reinstall Windows if it will let me, move the gpu and optane pcie drive around and see if any of that helps. *

You don't need Windows or the Optane to get through Post. Make sure your power is good. Maybe split the sli and try the good side just for a minute without cooling.

Which slot was the bad 1080 in?

[Mavtop]

First slot. It started throwing artifacts and then wouldn’t boot with it activated.*

Figured it out by isolating the bad card using the pcie lane switches.

Then verified that 2nd card in slot 3 continues to work well.

Now switched to another computers card while my broken one gets mailed away for repair.

Perhaps I should try slot 3 again to see if it was the pcie slot or the card itself that went bad?

I’ll try it out here in about and hour when I get home.

[Mavtop]

Well I figured it out in the worst way possible. Sheer luck.*

Turns out Rampage VI Extreme doesn’t like to boot when an SD card is in the reader.

After I took the card out, she boots like a champ.

Now I’m running 4.5GHz with 67C max in games and 82C max on Prime95! Yay!

[G75rog]

Good to see it was something simple.

[Mavtop]

Yeah thankfully it’s working now.*

Thanks G75rog for offering up some help. *I appreciate it.*

Sounds like a bit of a red herring but glad it's working for you now.
