Let me know what you guys find if anything. I could not find a specific issue. It could be a DLL or setting etc. but I could not find a consistent way to get the error to start happening. What sux even more is system restore did not fix it either no matter how far I would go back.
When I tried other support I got the three headed look. I found a way around this but would love to know what it is.

Tan, a Sig to go along with that would go a long way in knowing what benched those.

Yea. I too wish they'd expand the numbers out some of Sig limits.

That gives someone an idea of what you have while discussing issues and making comparisons.

I don't have a big boy system to test this Cry, but have you tried a minimal driver setup with a fresh reinstall of Windows (latest chipset directly from AMD, NVIDIA and LAN drivers - no Realtek anything nor any ASRock tools)?

I also found something interesting using Ryzen Master on my system: when I disable cores and overclock in Windows (via Game Mode which is a feature for Threadripper), I can't get the original multithreaded benchmark performance of the system, even after I re-enable all the cores in the UEFI, until I completely uninstall Ryzen Master. Single thread is unaffected though. I also seem to get random stuttering in games. This doesn't happen if I do it through the UEFI.

That's great!

Do you know if Ryzen Master does anything else to Windows other than use the "bcdedit /set numproc XX" command when Game Mode is used that would explain the small but permanent performance loss I noticed after overclocking with it?

I'm sure it's a Windows issues because the system performance goes back to normal after I uninstall Ryzen Master, even without a reboot.

Not a clue sorry. I don't use Ryzen Master, I am oldschool, if I can't do it through the UEFI I don't bother with it. 

That info would require some digging in the registry. Maybe try google, I am sure someone on reddit has gone looking. If I were AMD I would prioritize a single CCX and it's cache to lower latencies as much as possible, any time the infinity fabric comes into play latencies go up. This is just a guess though.
