Yes, version A27. The processor speed was reduced. After 6 hours of continuous use, I turned off the computer, rested for 2 hours, turned it on again and it froze when browsing the internet again.

I'm seeing crashes myself in my A27 machine. Freezes. So far they mostly seem to be related to undervolting and then pushing stability and performance tests. With CO off, I've seen fair stability, even when bumping up the BCLK a little - testing that with 100.875 Mhz right now.
But with my CO at -30 which stable in OCCT for 90 minutes, it passed... running Aida64 and stressing the CPU+FPU I would have complete freezes, or the stress test would fail with a hardware check. I've even had it freeze in BIOS - seemingly when I go into a saved profile and try to rename or interact with one. Really odd for sure, in that.
So I'm not precisely sure what's triggering it. I'm about to go try the AIDA test with -20 CO and see if it's stable there. On the upside, AIDA crashes pretty much within 30s if it doesn't like it, so... at least the testing is quick? But even with that, I can run the CPU, Cache, and Memory tests simultaneously and there's no issue, but it fails within a few seconds when I check the "Stress FPU" box.

I did a test, I changed the RAM memory presets in the Timings section.
These were the settings I changed that worked to reduce the freezing issues:
Memory Timing Preset: [Tighter] ->[Auto]
tWR: [60 T] ->[Auto]
tRFC1: [650 T] ->[Auto]
tREFI: [65535 T] ->[Auto]
tRTP: [12 T] ->[Auto]
tRRDL: [10 T] ->[Auto]
tRRDS: [4 T]->[Auto]
tFAW: [28 T]->[Auto]
tWTRL: [28 T] ->[Auto]
tWTRS: [5 T] ->[Auto]
But as soon as I open a video within the Telegram app, the PC freezes.
Edit: After setting CO from -11 to 0 only on cores 2, 3 and 4, the freezing stopped. I lost a lot of performance in CB 23, 24 and Geekbench 6.

Is your memory kit in the QVL list?

Another note around USB issues, was just transfering some files to an USB stick, using front ports. Cable is connected to one of the ports next to USB-C, only goes up to ~35MB/s... didn't even think about it since I was doing other stuff, until I put it in the other computer, front ports, and it did 300MB/s+ :/
Anyone else had issues with this?

Edit: Nevermind! Was being stupid. Write/Read speeds are completely different of course. It's performing to spec, even slightly better.

I did a clear CMOS with the button for the first time yesterday evening to test if it helps for the stuttering on cold boots with stucked PCI express speed (It was the first time I saw Bluetooth since the first boot/BIOS).
The boot in the morning was OK.

With the A27 version it is not useful to use the CO, as the problem of instability has returned. If I use a CO of 0 on core 2, the system is stable, but performance drops, because all the other cores are limited to working the same as core 2.

Thank you. Been following your posts since you seem to have the exact same issue I do. Waiting to see if you continue to have success with 1A27 before I update from 1A1A.

Stuttering like hell this evening's boot. Max PCI express 3.0 but stucked on 2.0. I enabled Spread Spectrum again but "nothing is wrong with the BIOS" but a lot of people are OK with 1A1A....
I don't overclock anything and I disable LAN 2.5, Wifi, Bluetooth and Realtek Audio.

Same, still crashing with the setup in my sig. I've tried tuning RAM down to 6000. I had a hard lock the other day too. My temps are fine. Tried undervolting both video card and CPU. Swapped RAM around. No joy.

Trust me, your problem isn't RAM, it's Curve Optimizer. It's the only setting I change that makes a difference in stability with this A27 BIOS.

According to my previous post, my core 2 is needing to be CO -0. If I put CO-11, it starts to get unstable. Every CPU is different, but I advise trying to change these CO settings to weaker.

I feel my issue is the RAM even though its on the QVL list for this board. I am getting the white flashing RGB before total shutdown. Im not getting blue screens, my system is purely shutting off on me when gaming. Specifically if I am alt-tabbed out to the desktop for an extended period and then switch back. Insta-shut off.

I gave 1A27 2nd try. Suprisingly, I found out disabling overclocking on the infinity fabric ( I was overclocking it to 2200 Mhz ) and memory overclocking (from 6000MT to 6400MT) seems to fix the cold boot stuttering issue for me. So far, it has been 2 day without any stuttering in cold boot. I am still running -30 on all code in CO.
This is the memory that I am using for my 9800x3D

I had shutdowns in one specific case. I would just open the Topaz Gigapixel program, process some image, and the computer would shut down. It stopped happening like this after I changed the PSU.

Thanks for giving it a try. Now I know not to bother. The stuttering on some boots/wakes due to wrong PCIe speed is exactly what we have in common. I was also seeing it without any overclocking, using fully reset CMOS settings. I am able to do very mild OC on 1A1A without issues, though.
