Yes, the newest AMD chipset drivers are installed (minus the RAID drivers, as I don't have RAID storage). In reference to the 99.8 MHz, I suspect this is a result of the default spread-spectrum clocking on the board and not something I see as being related to stability or performance. I'll try an Nvidia card tomorrow.

Hello all, I recently built a fairly high specification Win10 desktop PC to handle certain tasks such as radiation transport modeling and video rendering. Unfortunately, it has been extremely unstable, exhibiting numerous crashes, BSoDs, and subsequent refusals to boot Windows. I'd be very interested if other people using similar hardware have had similar problems, or if any super-sleuths can look at the attachments and point me in the direction of a fix. The oddest thing about my problem seems to be its correlation with lightly-loaded operation; it runs just fine under moderate to heavy CPU / GPU loads, but is really unhappy with unloaded operation. One naive guess is that there may be a voltage regulation issue on the mainboard. Anyway, I am open to suggestions and further questions and I hope to get this PC in better health. Pointers toward differentiating the diagnosis between mainboard, CPU, memory, and GPU would be particularly helpful! The PC will run fine IF the CPU is heavily loaded. My usual workload on this machine in its short and tumultuous life has involved parallel MCNP simulations that run for a week or so and keep the processor running at ~90% load with 24 threads. It just runs and the CPU temps hover near 73 deg. C. HOWEVER: if it's unloaded, it is highly liable to throw display driver resets and BSoDs. This build really seems to hate AMD graphics cards, throwing regular GPU driver restart errors with both the R9 390X (a fairly old card) and an RX 5700 (new) using the most recent graphics drivers from AMD. A frequent occurrence are LiveKernelEvent errors referencing LKD_0x141_Tdr:6_IMAGE_amdkmdag.sys and LKD_0x117_Tdr:9_IMAGE_atikmpag.sys. Runs Furmark without problems so far. Again, the machine is most error-prone when it is just idling! Currently running with the memory D.O.C.P. profile enabled, but it's hard to tell if this makes any difference in the bad behavior (have tried with this on and off). Memtest runs 4+ passes with 0 errors on the currently installed DIMMs I have swapped the OS SSD with another of the same model and this did not fix the issue No history of overclocking (with exception of D.O.C.P.)
