Z170 and NVMe stability issues

Hello AT. Long time lurker here for some advice.

My ASRock Z170 Extreme7+ becomes unstable (Intel Burn Test / Prime95 / Handbrake errors) when I have my 2x Intel 600ps installed. I don't blue screen, I'm just getting "Zero Errors" in IBT/p95 the results return 0 when they should be something else, or crashes (handbrake). I've been troubleshooting for a few days and am at a loss as to the exact culprit. Before I start to RMA stuff, I'd like to hear what you think. I'm not overclocking and I'm monitoring temps every stress test (top out around 70c).

Things I've tried:
  • Unplugged everything except whats necessary to get windows up and testing. Everything becomes stable when I remove the NVMe drives.
  • Tried latest and previous motherboard bios (7.3 / 7.1)
  • Fresh windows install
  • Memtest86+. Only testing with one stick right now, normally 2x16GB DDR4. Also tried different sockets.
  • Different, known good power supply.

I'm currently trying different M2 ports (there are 3). Then I'll try 1 NVMe at a time to see if a specific one is causing problems.

Some peculiarities that are making me think it's my mobo:
  • strange readings in cpu-z when using default "auto" settings (strange ram speeds and bus clock reads 99.8 - 99.9, reported cpu voltage does not match what i enter manually)
  • Video card was doing some really funky stuff. It made me think I had a dying video card or power supply.
Any settings I could try tweaking to help get this thing to work right? I'd appreciate the help.
 
Maybe send an email to Asrock's tech support. If they can replicate the problem, in the past they have sent out custom BIOS updates to people.

I can't imagine too many people use multiple Intel 600p drives, so it could be a compatibility issue/bug.
 
After much more troubleshooting it looks more and more like a RAM related issue. Specifically, timings and specs from the XMP profiles. I'll try ASRock tech support next. Thanks.
