Apologies for the delay... turns out it was a simple matter of taking off the motherboard battery and putting it back in. Who knew.

It after you try what datonyb suggests .. and it still doesn't post .. try your older components (cpu?gpu?) and see if it will boot]]> Tue, 19 May 2020 00:22:01 +0000 https://forum.asrock.com/forum_posts.asp?TID=14412&PID=75615&title=x370-killer-sli-ac-unable-to-post#75615 https://forum.asrock.com/forum_posts.asp?TID=14412&PID=75614&title=x370-killer-sli-ac-unable-to-post#75614 Author: datonyb

my taichi x370 messed about when i installed the 3800x

to solve ?????????

remove power plug from wall
flip out the cmos coin battery from motherboard
press and hold case power button 30 secs
insert 1 ram stick only in slot a2
refit coin battery
plug into wall
and power on (wait a few mins for board to memory train)
then it will boot to bios
save an exit
fit 2nd ram stick to b2
boot to bios
save n exit
boot to bios
set ram xmp
reboot all fine to windows


JUST TO ADD , the cmos clear button dosnt work for me to clear this issue
hence the remove battery and drain all capacitors method

Are you sure that's not a GPU issue? The board POSTs, there's just no video output from the GPU. If you have a PC speaker connected properly, you should hear one short beep when everything is ok, or long beeps if there's video or other failure.]]> Mon, 18 May 2020 09:33:52 +0000 https://forum.asrock.com/forum_posts.asp?TID=14412&PID=75585&title=x370-killer-sli-ac-unable-to-post#75585 https://forum.asrock.com/forum_posts.asp?TID=14412&PID=75582&title=x370-killer-sli-ac-unable-to-post#75582 Author: Daemones

Hello everyone,

A couple months ago I inquired about updating the BIOS of my x370 to be able to use newer AMD CPUs, such as the Ryzen 9 3900x. Fourm post [URL=http://forum.asrock.com/forum_posts.asp?TID=14273&KW=&PID=75038&title=updating-bios-on-x370-killer-sli-ac#75038]Here[/URL]


I was successful in updating the BIOS to the latest version, 5.8. Had no issues running my previous build.

Current build is:

AMD Ryzen 9 3900x 3.8 GHz 12-Core Processor

ASRock X370 Killer SLI/ac ATX AM4

ADATA XPG SX8200 Pro 2 TB M.2 SSD

Geforce RTX 2080S 8GB


Because the GPU shipped late, I was only recently able to begin this build. Following installation of the components, everything turned on, however the moba failed to POST. No USB connection was able to be acquired by the motherboard, however all components such as the GPU, CPU, and fans were running as intended. Except CPU fan speed would increase for a few seconds, but decrease for about 10 seconds.

Attempts to troubleshoot have been unsuccessful at this time... tried switching out RAM sticks (2x8GB)to different slots, no luck. Also gave the motherboard 10 minutes, since first few POSTs tend to take a while the first few times.

If it comes down to it, I'll bite the bullet and purchase a newer motherboard, however I would like to see if there is something I am missing.

Any help would be appreciated. Thank you!
