I have a rebadged Tongfang laptop (NB02 GMxRGxx w/ Ryzen 9) and upgraded it shortly after purchase.
The machine arrived with lower capacity Samsung SODIMMs. Swapped in 64GB of Crucial DDR5.
Shortly afterwards the machine became instable to the point of RMA. Kernel logs clogged with all sorts of panics related to NVMe, PCIe, and filesystem. Freezing. Reboots.
Spent hours diagnosing it. Many permutations of kernel command line arguments; pcie, acpi tables, iommu. All for naught.
The machine passed memtest86 / memtest86+ with flying colors.
bonnie++ absolutely trashed it. reliably.
Occasionally the NVMe drives fell off the pci bus and it wouldn't boot until I disable the slot in bios, power cycle, then re-enable the slot.
Fast forward to me getting fed up with a dysfunctional system, I attmepted RMA and gave them the rundown of all the weird seemingly chipset related failures.
They pushed back with "Try our RAM again."
I nearly had an aneurysm when everything was stable again.
After thanking the support staff profusely I bought larger capacity Samsung DIMMs in the same chip family. Still running flawlessly after almost a year.

Maybe try new RAM for yucks? ;)
