Just as a quick update: In addition to setting the PCI slots to explicit 1X / Gen3, I have clocked the CPU down to 3.5Ghz and the RAM to 2400Mhz. In this configuration, I can't get it to crash. That's unfortunate some mobos don't have the option to explicitly set those speeds on PCI slots. C6H is X370.

nw15062 is on to something (for me). Disable "Super I/O Clock Skew" and put the WiGig card in a PCI slot you can explicitly set to X1 bandwidth, Gen 3 mode. I haven't verified that each of these steps is necessary, but I shotgunned all three changes to my system and everything works now (edit:) it becomes playable. It still BSODs. Here's the message I sent to support today: I'm deviating a bit from the instructions because I believe it's been fixed (I've gotten in an hour of play time with several games and no issues). Previously, the WiGig card was plugged into the slot PCIEX1_1 on the Asus ROG Crosshair 6 Hero, nearest to the CPU: This seemed to be in accordance with the suggestion in the manual. I left the BIOS untouched. This resulted in crashing at various times -- sometimes right when starting SteamVR, other times at the beginning of games, other times 10 minutes in. Earlier today, Reddit user u/nw15062 made this suggestion to me: "Explicitly assign the pcie slot to 1x mode and disable super I/o skewing in the bios under advanced> onboard device configuration." I moved the card to PCIEX4_3, which I then manually assigned to X1 bandwidth and GEN3 mode, and disabled Super I/O Clock Skew. Now I'm up and running. I would like to test these variables independently -- I wonder if the clock skew disable is enough to fix it since the DPC Watchdog Violation is, in general, a timeout error.

Yeah, for the record, there's no statement of "Intel CPU required" in the Vive store, and the manual lists system requirements including: "Processor Intel® Core™ i5-4590/AMD FX™ 8350 equivalent or better" All of these are 8350 or better. I don't want to read too much into that message from support, but to say it's "incompatible" is bothersome. You can't sell people something for $300 and then retcon the system requirements to fix your bug. I'd like an update with a root-cause analysis ASAP, HTC. Is there a path to solving this bug or is it really incompatible?

For folks posting here, it's probably a good idea to post the games you're testing with. It seems from this thread and also another over at Reddit that some games are durable (like AudioShield) and others are very much not. We might see a pattern.

Another one here. Ryzen 7 1700 ASUS C6H 1080ti All OC disabled. All drivers latest. I've tried several settings in SteamVR, inclusive of: - disabling camera - disabling all perf monitoring - disabling reprojection - enabling lock mode and locking the screen so that only the HMD renders Nothing works so far. What I do notice (and a Reddit thread corroborates this) is that some games don't have a problem. For example, AudioShield works for a good while just fine. The Lab crashes quickly. It is either hard crashes to reboot, or sometimes a BSOD indicating the DPC watchdog violation. Copy-paste others' comments here about the acceptibility and severity of this, etc.
