well im glad we got to the bottom of this

yes technically 3900 is from version 5.4 up

i would suggest 5.8

for the reasons of

you board is virtually the same as my taichi
im on 5.8 and its stable and fucntional


now one tip i must pass on

when i bought my 3800 i flashed bios to 5.8 using my 1700 cpu


all working fine
i then installed the 3800 and it wouldnt boot to bios

i finally got to thebottom of this by using JUST ONE ram stick in a2 slot
and it booted to bios , i could then switch off and insert 2nd stick in b2 and reboot set the xmp for ram etc

after this if i ever have to clear the cmos (reset bios )

i always have to use JUST ONE ram stick for the very first boot


i mention this as our boards are very very similar and you might have same issue]]> Sun, 03 May 2020 04:27:39 +0000 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75039&title=updating-bios-on-x370-killer-sli-ac#75039 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75038&title=updating-bios-on-x370-killer-sli-ac#75038 Author: Daemones

Updating now from 5.1 to 5.8!


Thank you for the help! Greatly appreciated. So since this is updated, it should have no problems with compatibility with the Ryzen 9 3900x? ]]> Sun, 03 May 2020 04:06:44 +0000 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75038&title=updating-bios-on-x370-killer-sli-ac#75038 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75037&title=updating-bios-on-x370-killer-sli-ac#75037 Author: datonyb

Update: It's recognizing 2.40. Guess what I'll do is update each time until I reach the latest update.

My BIOS version is 1.6 according to CMD prompt.

Followed the steps and added 3.5 bridge to the USB. Loaded defaults on BIOS but still is recognizing the USB and seeing the file... but still giving the "no image file detected" message.

I noticed there are a couple versions before 3.5... it may be a pain, but I could try going from 2.40 (the start of the updates) and onward until I reach 3.5? ]]> Sun, 03 May 2020 02:12:53 +0000 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75034&title=updating-bios-on-x370-killer-sli-ac#75034 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75033&title=updating-bios-on-x370-killer-sli-ac#75033 Author: datonyb

aha i think ive sussed it

what current bios version ?

you HAVE to install version 3.50 A BRIDGE BIOS before anything higher

AND THEN V 5.10 before anything higher


im guessing your version 5.80 is locked out due to not having 5.10 or even worse not being on a bios above 3.5 yet


to clarify if you are on version 3.40 or lower you need to flash
3,5

then 5.10 and then 5,8]]> Sun, 03 May 2020 01:33:50 +0000 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75032&title=updating-bios-on-x370-killer-sli-ac#75032 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75031&title=updating-bios-on-x370-killer-sli-ac#75031 Author: Daemones

Had a Kingston 1 GB lying around and gave that a try. I attached it to the back of the motherboard but had no luck. The BIOS identifies the USB and for a split second reads the "X370KLI5.80" file, but still says it cannot find the image file. ]]> Sun, 03 May 2020 01:24:45 +0000 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75031&title=updating-bios-on-x370-killer-sli-ac#75031 https://forum.asrock.com/forum_posts.asp?TID=14273&PID=75016&title=updating-bios-on-x370-killer-sli-ac#75016 Author: datonyb
