PC still keep rebooting with the error "Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Cache Hierarchy Error

[chopinanopolis]

I've had this issue since I built my PC in feburary, I've made multiple posts across different forums, subreddits, discord servers etc, and it still keeps happening. My monitor goes black, the sound either hangs or cuts out entirely or just skips, and it reboots. Sometimes I'm just stuck with a black screen for like 20 seconds, with nothing happening, and sometimes it reboots immediately. It has happened while gaming, once or twice while just idle and two times while downloading an update through the Black Desert Online launcher specifially. Sometimes it runs perfectly fine for day, some games (SkaterXL) only crashes on one specific modded map, and only in certain spots, other than that, not at all. Meanwhile No Man's Sky crashes after about 5-10 minutes everytime. Something like Apex Legends can run fine for days, or crash every few minutes, it's completely random. Temps are all perfectly fine. Event Viewer always says the excat same thing with differing Processor APIC ID's. I've at this point tried everything, and I'm literally clueless and frustrated. I bought a new motherboard, and installed it, hoping it'd work, nothing. Same shit keeps happening with the exact same errors. I've rplaced or rma'd literally every single component except my SSD, and it still happens. I don't know what to do anymore. I feel like i wasted 700 bucks cause this damn box of metal refuses to work correctly, and I just can't figure out why.

Board BIOS update?
Board Chipset update? (AMD only website)

What’s the speed of DRAM, and did you try to lower it just for testing?
What is the speed of FCLK:UCLK?

Is DRAM on the QVL of the board?

Can you test a completely different DRAM?

Cache hierarchy errors are usually related with infinity fabric (FCLK) and some times with memory in general.
Could also mean in rare occasions a faulty CPU, but you said you rma everything…

Can we get a screenshot of ZenTimings app?

Replace the cpu, the memory controller is unstable. Lowering the DDR speed may buy you some time but the issue is terminal

Wow… hold your horses

OP said that everything was RMA-ed except SSD.
Have you heard about CPU/board/DRAM incompatibility on AM4 that causes instability? Most of it is ironed out with newer BIOS versions but still some may exist.

Isn’t it wiser to try and pin point what exactly is the culprit and if there is any.
Isn’t worth to try first updating everything before getting into process of replacing something?

Bios and Chipset is all fine, just installed the board today and updated everything. Actually no, scratch that, I think theres a new bios version available, but I lost my only usb that I can format, so I'll have to get a new one. But I dont think its that either if its still the same issues as with my other mobo, since on my old one the bios was up to date. The current version on this board is from 02/01/2024, so its two versions behind, but not ancient.
Dram max is 3200, havent enabled any xmp in bios, so rn its running at 2400. FCLK is on auto, so I'm assuming they're matched up correctly.
RAM is on the QVL list as well, and I already tried a different kit on my last Mobo, but that didn't make a difference. I sent it back afterwards, since it didn't change anything.

And yeah, I already sent the CPU back to AMD and got it replaced, and th exact same erros are still happening at the same times, so I'm assuming the CPU, atleast in it of itself isn't at fault.

And ofc no power supply,

Could be the game or memory at this rate

Could be a corrupt os too
