Odd Cold Boot Issues - Mobo or CPU£

Sorry for the not-much-of-a-necro necro. Have an update as I finally had some time to put everything back together. I got the Ryzen 7700 RMA'ed through AMD, and received a brand new 7700 CPU in box in its place. Just put it all back together yesterday. At first I was having phantom issues, thinking "oh, there's no way things could still be bad". Well, sadly, I was wrong. I saw minor stuttr and tired to shake it as the above, so I rebooted. The new processor is noticeably better. I was able to properly OC my DDR5 6000 to the rated speeds with no issue, Prime95 running through multiple tests with no failures whatsoever. Another ~7+ hours upon that 2nd boot of pretty heavy gaming (A StoryWealth Fallout 4). This morning, however, I decided I'd boot up and head back to sleep to see for the cold boot stability. Upon waking ~1hr later, I noted the USB dropouts were back, and Event Viewer reporting Bluetooth crashes and the driver being unloaded. Okay, I've seen that before, and I don't have to use BT. Physically removed the BT adapter, and I'm on the first "hot" boot, so I'm still keeping an eye, and will check for stability next cold boot.

Also, still have heard absolutely nothing from ASRock except for the auto-response. Looks like I'll be jumping ship to another reputable brand. Two PG Riptide boards in a row with these issues. I really though I had it whittled down to the CPU. Thought maybe the first CPU was "damaged" from the bent pins on the first board. Just... UGH. Really getting tired of this.

Necroing my own thread.

I was able to get the Ryzen 7700 replaced via RMA from AMD. However the freezing and USB stuttering was still occurring. I was able to properly clock my RAM to 6000MT/s which was nice, but the issue came back within the typical 5-10 min period, was to say the least was disappointing. I submitted a 3rd request to ASRock support, so hopefully any info I missed or whatever is able to be looked at.

Thank you to all who assisted me so far with this.
