That was the exact type of computer command I was looking for on my own, I was looking for page flushing tweaks, that looks like the exact tweak that I would have expected to solve this type of bug. The registry tweak didn't work, it's unresolved still.
I have a crutch setup; the Active Page Threshold feature is set to ~4GB
One clue could be when it does resume from failing to enter Intel Rapid Start suspend state (is that S4 or S5?) it resumes the same way it would as if it were resuming from hibernation
