Thanks for the info DontAsk. 4.10 seems to be resolving quite a few issues which
is great to see. ]]> Sun, 08 Mar 2026 16:25:49 +0000 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=201018&title=x670e-pg-lightning-no-post-on-cold-boot#201018 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=201017&title=x670e-pg-lightning-no-post-on-cold-boot#201017 Author: DontAsk

I already updated the BIOS of my X670E PG Lightning and the issue "no boot after a temporary disconnected power supply" which has been introduced with v3.40 then continued with v3.50 is solved with v4.10.

Hint: The included Agesa version behaves different regarding the memory trfc values. The values trfc2 and trfcsb are now important thus if you manually adjusted/reduced these in a profile based on a previous BIOS version then it could be that your PC won't boot --> clear CMOS and go with default values or test with more conservative values ...]]> Sun, 08 Mar 2026 16:04:06 +0000 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=201017&title=x670e-pg-lightning-no-post-on-cold-boot#201017 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=201016&title=x670e-pg-lightning-no-post-on-cold-boot#201016 Author: Armus

I was struggling with the same problem, x670e PG Lighting, Ryzen 7800x3d, 2x32GB ram 6000Mhz, Memory Context Restore to Disable did not help, only as colleagues mentioned downgrading the BIOS to version 3.30 eliminated the problem.]]> Sun, 21 Dec 2025 21:01:55 +0000 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=200651&title=x670e-pg-lightning-no-post-on-cold-boot#200651 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=200401&title=x670e-pg-lightning-no-post-on-cold-boot#200401 Author: Xaltar

If you are not using a 9k series CPU then you can just stick with 3.30 for now until
user reports indicate the issue has been fixed on a future update. I am not speaking
for ASRock here, just a moderator giving my recommendation. As far as I am aware
there is no benefit to 7k series CPU users in updating past 3.30 on your board
currently.

I honestly wish AMD would get their act together. They have bred a very unhealthy
culture of obsessive BIOS updating, so much so people actually think BIOS updating
is essential these days rather than something you only do for new CPU support
or for the odd security update as it should be. It should be a case of:
"If it ain't broke, don't fix it".]]> Fri, 14 Nov 2025 23:30:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=200401&title=x670e-pg-lightning-no-post-on-cold-boot#200401 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=200398&title=x670e-pg-lightning-no-post-on-cold-boot#200398 Author: karzinogen

Similar issue here.

After flashing 3.40 and configuring everything (PBO, CO, XMP), everything is running rock-stable, just as it did before. But the system won't cold-boot after shutdown, except CMOS is resetted. Power supply was on mains power between boots.

After going back to 3.30 everything is perfectly fine again.
Haven't tested 3.50 after users reported it's not fixing the issue.

2x 32GB G.Skill F5-6000J3238G32G DDR5-6000

Just wanted to chip in and say that I got the same issue after updating the BIOS to 3.40 (and also 3.50) with cold boot. Downgrading to 3.30 solves the issue.

Had the same issue back in the day with my ASRock Z170 OC Formula after cold boot, never solved it (even changed CPU, RAM, Power Supply and GPU without success) and got myself another board (different brand), worked plenty of years without any troubles with the new board.

I don't see the point in changing my hardware when the problem is -as it seems- BIOS related. My components are brand new, working flawlessly with 3.30. The issue is the BIOS or some setting (related to the newer BIOS versions) which I coulnd't figure out yet.

The problem only occurs to me when shutting the pc down and cutting the power completely (removing power cord/switch the power strip off), but if I just shutdown the PC and restart it the next day/hours later without cutting the power, it boots fine (no such issue with 3.30).
It also doesnt matter if I leave the RAM at default settings (=not EXPO/OC related in my opinion), PC won't boot after cutting the power.

Latest BIOS 3.50 is not targeted at this issue.

My research shows most users with similar issue can pass a cold POST only if they run the PC for a while and then restart it. So this is most likely a power delivery on start issue.

E.g. faulty PSU voltage line to CPU or mobo, faulty BIOS battery, anything related to voltage power droop when capacitors are discharged for cold boot (could be PSU, CPU or Mobo hardware problem).

Problem may be partially or fully remedied by swapping components or changing voltage settings in BIOS.]]> Sun, 05 Oct 2025 16:13:57 +0000 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=199149&title=x670e-pg-lightning-no-post-on-cold-boot#199149 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=199136&title=x670e-pg-lightning-no-post-on-cold-boot#199136 Author: DontAsk

Unfortunately the new BIOS 3.50 continues this bug from BIOS 3.40. Back to BIOS 3.30 and no issues.

BTW, I use a power strip with a switch thus if I switch the power on that strip and press the power button at the PC it always starts without issues since the last 2 years but only with BIOS versions older than 3.40. With the versions 3.40 and 3.50 it will never start.]]> Sat, 04 Oct 2025 02:12:02 +0000 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=199136&title=x670e-pg-lightning-no-post-on-cold-boot#199136 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=199072&title=x670e-pg-lightning-no-post-on-cold-boot#199072 Author: DontAsk

Next week, this motherboard will likely be one of the last to receive BIOS v3.50 (includes Agesa 1.2.0.3g). Hopefully, also the above mentioned cold boot bug which only exists in BIOS v3.40 has been silently fixed. We will see ...]]> Sat, 27 Sep 2025 01:21:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=113331&PID=199072&title=x670e-pg-lightning-no-post-on-cold-boot#199072
