MEG X670E ACE - code 15 long boot times

[chou_w156302d7]

So far, my biggest issue was the boot times. However, one other item that seems to happen every third boot up or so, is that the screen goes black right before the windows login screen pops up and I cant "wake" it and have to power down and reboot. Using an EVGA 2070 Super with current drivers. I have turned off integrated graphics in the BIOS. Next thing I will try over the weekend is different display port socket, then will try HDMI if it still happens, then use the USB-C out to DVI connection on the card as a last resort.

I am also having this issue with the odd reboot going to black screen. It mostly happens when I try to turn on the computer in the morning. Throughout the day if I need to reboot it seems to boot up. However, when it doesn't the screen is black, monitor detects a signal but the the boot process does not advance to the cursor/(-) at the top left of the screen. It just hangs there until I press the reset button. I am also experiencing really long boot times. I have B650M Mortar, 7700X, and 32GB Corsair 5600, EVGA 3090 FTW3. All drivers are up to date and I flashed the Mortar bios yesterday with the latest. Wondering if anyone has found a good solution to both the black screen and slow boot issue

You want the BIOS settings for my 5900X system ? I'm a bit confused here..
(If that's the case, most people with a 5900X + M.2 drive boot to Windows between 7-15 secs)

In any case, my build :

-Tomahawk X570S Wifi
-R9 5900X
-32GB 3600mhz G.Skill Trident Z Neo
-3080 Ti FE
- 2x Gen4 M.2 NVMe Aorus 2TB

Fast boot enabled, onboard audio disabled (external DAC) and standard Windows 10. And that's it

Still waiting for them screenshots Friend
on how you get sub 10 seconds boot from pressing the power button to Windows log on
See over 10 seconds no matter what I do so whats your secret setting Friend
The one you seem unable to or willing to share.

I guess the problem still persist. I just set up a new system today and it also gets stuck on code 15 for quite some time. I have a 5950X system and it boots pretty fast. I need the virtualization setting on for VMware so I can't turn that off. It's not the end of the world, I just wonder why it's so slow and why they haven't fixed it.

Well 12 hours later and slow boot times are back.

this is because of memory training. your BIOS might be set to do the training every time.

I tried setting it off and I can't boot into Windows unless memory training is ON (which is the default). Since my first contact with my board I always had this issue and decided to let it be.

I am very well aware of the reason. However, the way the function is supposed to work, is that it trains once, remembers the settings and then will NOT go through the training sequence every time unless there is a hard system reset/power loss.

I imagined so... I just wanted to say that ever since I put my hands on my X670E Carbon Wifi I never managed to turn-off this memory training thing because if I do so my PC won't work.

FYI
If you enable Memory Context Restore, you have to enable Power Down option in DRAM menu. Otherwise, system will freeze constantly. It is a bug which has been a while.
Also don’t try Memory Context Restore on Samsung based DDR5, it would get stuck at reboot.

Thanks for the tip. My memories are G.Skill TridentZ 6000MT/s with SK Hynix chips... and although this slow boot times suck I simply don't turn off the PC anymore, I just put it into sleep mode.

@lostking20015bf02e6 I just did as you described and enabled Memory Context Restore + Power Down in the DRAM menu and the boot times are super fast now.

Thank you.

Thank you.

What is your boot time ? From pressing power on to Windows desktop ? Cheers

For your reference, I have 3 mechanical hard drives, which takes time to spin up on booting.

Around 25 seconds but the task manager says 18.4 seconds

Hi,
I am having the same problem. (Code 15)
I did all the suggested settings but it didn't work.
With Expo disabled, boot time decreased from 75 seconds to 30 seconds.

Motherboard: MSI MPG X670E CARBON WIFI

I buy today msi ace x670e with same ram, around 40 seconds before pass the code 15, but after disable the cpu virtualization in BIOS
option under cpu it call "svm", now post in 3 sec, I cannot see the code 15 anymore... I hope it help

I just bought this motherboard to build a new computer. I initially configured it with two (2) Corsair Dominator Platinum 5600Mhz RGB 32GB sticks for a total of 64GB. A few weeks later I decided to upgrade and added two more 32 GB sticks of the same memory. Thats when I started having my problems with very slow boot times. I was up to 3min in some cases. The solution you provided here solved my slow boot time issue. Initially I couldnt find SVM on the boot menu to disable. But I used the bios search function,found it , disabled it and now my system boots in 8 seconds. thanks so much for this solution.

But it's not really secure to disable SVM, anyway it's not a long time solution...

Not to worry. I found a few other settings to change such as the Memory Failure Retry - changed it to
2 times from 0. Also the enable setting on Memory Context Restore is the setting that worked for me. After multiple successful reboots I changed the SVM setting back to enable BIOS CPU virtualization once again. It works great and no slow boot times now. Also I'm not using XMP profiles as the motherboard had issues booting successfully with the XMP profile enabled.
