X670E Taichi crashes / reboots

Just updated to the latest bios 1.14.AS06 [Beta], verified it booted fine with 7700X, then replaced 7700X with a new 7950X from AMD RMA. Booted it, and it booted to lock screen successfully. Rebooted and upped the 4x16Gb to 6000mt/s and so far it has been stable. Last time it would crash all over the place, bios, lock screen, and 2 seconds after logging in no matter the ram config. Smooth and fast so far. Still took 2m+ to initialize the ram so that clearly han'ts been fixed, but swapping the speeds is a lot faster now.

Just to let people know Amd motherboards do not support standard power management of drives (DIPM) I used to have issues with my X670 Taichi, I've found that you need to change AHCI Link Power Management to HIPM...

I am seeing the same thing with 14.AS06 beta. Don't know if my devices are wigging out but it looks like that release is no longer available at the moment.

RAM set at 6000mhz, the device resets overnight and RAM speed resets to 3600mhz
RAM set at 4800mhz, no restart yet.
RAM set at 3600mhz. still restarted overnight twice.

Seems like bios isn't even properly saving/applying the setting. I think it is generally about 6hrs after I stop using it. Sleep is disabled and I just turn the displays off at night. I really hope there is a new release soon...

Hey all, glad I came across this topic as I'm struggling with these problems on my X670E board for weeks now and its driving me crazy.

I haven't been able to get it stable unfortunately, with neither BIOS version.

My specs:

AsRock X670E Taichi Carrara
AMD Ryzen 5 7600X
32GB G.Skill Trident Z5 NEO DDR5-6000 CL36
AMD Radeon RX 6900XT

I've been experiencing the exact same coldstart issue on BIOS version 1.11, where the PC would simply restart within 5 minutes after starting the PC when it's been off for hours; no bluescreen or anything, just a random freeze/restart. This would not happen when the PC is started while being warm.
Other than that, the system was stable.

After reading that the issue got resolved for some people by upgrading to newer BIOS versions, I got my hopes up and did the same, upgrading to the 1.14 AS06 beta bios.
This unfortunately made the system even less stable. On that version, I started getting bluescreens multiple times a day. Weirdly, apps started randomly crashing and Chrome tabs would also stop working randomly when browsing websites.
Downgraded to 1.11 AS06 this morning, hoping to find the perfect middle ground. However, bluescreens got even worse. System was extremely unstable.

So I ended up reverting back to 1.11. The system now seems to be stable again for the day, but I'm pretty sure this will reintroduce the coldstart issues again..

One thing thats especially bad in my case, is that whenever a freeze or bluescreen happens, my PC then refuses to boot into windows for a good 15-20 minutes as it just results in a black screen after the AsRock logo. I then have to shut off the PC and start again, repeating this process probably like 10+ times until I finally get a working boot into Windows. This is extremely tedious.

So far, this has been an extremely disappointing experience and I hope AsRock can work out the stability issues.

I came across an interesting post on another forum where someone said, they are able to prevent the coldstart freeze/restart issue by running Cinebench right after booting into windows to make the CPU work hard for a couple minutes. Apparently he hasn't had any coldstart issues since doing that. I will try doing that for the next few days going forward and see if that works for me.

I have similar issues, similar config: 7950x, x670e taichi with 64GB (4x16GB) ram. Same instability, crashes etc. The only way I have gotten it stable is by disabling all C-state related settings in the bios. There are a few places you need to disable it, in ACIP config, and in CPU config. Once I do this, I am fine and can run EXPO at 6000 speed. I am on 1.14 AS06 bios. Even with this relatively "stable" config, I still see weird issues when messing with settings in ryzen master, like in can get out of "sync" where the bios says expo is enabled, but ryzen master does not... Or ryzen master refuses to start. Anyway, after clearing settings and only making changes in ryzen master and C-states disabled, I can finally get it seemingly rock steady, even with PBO all core offset (-11) and expo profile.
