Mag B550 crashing randomly

[tourbu12b602a9]

Motherboard: Mag B550 Tomahawk MAX wifi 7C91
Processor: Ryzen 7 5800X
Ram: G.SKILL Ripjaws V Series 64GB (2 x 32GB) 288-Pin PC RAM DDR4 3200 (PC4 25600) Desktop Memory Model F4-3200C16D-64GVK
GPU: Zotac Geforce RTX 3070 ti Trinity OC

This is a new PC build. Everything on the computer works well until, after gaming for about 45mins -1hr the computer will randomly crash. I have updated all my drivers, updated windows, the motherboard is on the latest firmware. I have tried other ram and done a second clean new install of Windows 11. It always results in the same problem.

Event 46, WHEA-Logger
A fatal hardware error has occurred.
Component: Memory
Error Source: Machine Check Exception
The details view of this entry contains further information.

I have tried everything I can think of to fix this, and I am beginning to think I got a bad motherboard.

Are you able to recall what was going on when / just before the game crashed?

At the moment there are too many variables in play with the CPU and GFX card, both have a form of dynamic overclocking and if not working correctly can cause the game to crash. Both issues also operate in a way that means max power and heat stress testing can all pass with no issues. This is because at a constant load the CPU and GPU will also be at a constant frequency / voltage whereas during a gaming environment both are changing many times a second, the CPU/GPU frequencies and voltages will be all over the place.

So for the purpose of fault finding it's best to control the CPU and GPU.
- CPU is easy, you simply fix the frequency to the base clock of 3.8GHz. (In the BIOS set the CPU ratio to x38) and try gaming again.

- GPU swap out or limit the boost clock using MSI afterburner software.
once installed -500MHz from the GPU, make sure you click the apply button.

Thank you for this suggestion, I am hesitant to report this as I may curse myself. But I tried the CPU fix in the bios, and my issues seemed to stopped all together. I don't know if I have played long enough chance to really test it out, but I have played 3 different games for over a hour, and one game for over 3 hours and none of them crashed. Temps all seemed good. Maybe its fixed?!?

So x38 CPU ratio, keep playing

While you do that can you also use hwinfo to capture the peak temps (max temps), and what games are you playing?
For example cyberpunk after 30 mins with a screenshot of hwinfo (show everything like you have done before)
This is important as if the CPU is at 3.8GHz and peaking at 80 Deg C it's not good.
