Killer SLI/AC Boot Loop/No Video

I see everything there except you mentioning a graphics cad, which is req'd for Ryzen as Ryzen doesn't have a dGPU built in.

Don't use anything but Instant Flash from within the BIOS itself.

Are you 100% positive BOTH Fortis sticks were fully seated into the slots? You should hear 2 clicks when they seat properly. G.Skill uses IIRC an 8-layer PCB that is sometimes tricky to fully seat.

Ok. Instant Flash isnt available in the Tools menu. All I see is driver update and some other options. Nothing about Instant Flash or similar.

The Instant Flash tool is added in UEFI version 1.60. But to install 1.60 the only options are the DOS and Windows methods, as you know.

I guess you don't feel like using the DOS method, since that requires a bootable USB flash drive.

Actually, the DOS method runs Instant Flash within DOS, if you check the DOS instructions, here (Sorry, the forum link tool fails on some URLs like this one, so text only. Just highlight it, right click and select an Open option):

The Windows update method simply seems to have the most failures. I'm not sure why, I get the feeling people use it with the CPU and/or memory over clocked, and who knows what programs running at the same time. All of that is a mistake.

I can't say it would be better to use the Windows method for the 1.60 version, in order to get the Instant Flash feature, and then update to 2.00 with Instant Flash. I trust Instant Flash, never had a failure yet, but the choice is yours.

If you use the Windows method, no over clock of the CPU or memory, stock/default UEFI settings only, unless you have RAID enabled, don't boot with the SATA mode changed to AHCI if you installed Windows in RAID mode. Actually this advice applies to any type of UEFI update.

Instructions for using the Windows method are here, please read them first:

Super important thing at the bottom of the instructions. IF the update fails for some reason, DO NOT TURN OFF THE PC! That will guarantee a bricked board!! Try to get into Windows again to repeat the process, or consider your other options.

I'm not trying to scare you out of doing the update, just coaching you about things I've known other users have done in the past, and their bad results.

PLEASE have no other programs running! If you have whatever programs auto-starting, kill them with Task Manager first. You want a super stable Windows environment. I don't care if it is CPU-Z or a hardware monitoring program, don't have anything running.

Two things I will add are, copy the Windows update download file to your OS drive if it is not already there. Unzip the file and go into the folder created and follow the instructions. When you run the UpdateBIOS batch file as shown in the instructions, right click on it and select Run as administrator.

Please let us know how it goes.

Great, thanks!

I still don't understand why some users have trouble with it.
