I have just done some more testing.
XMP timing enabled, ram FREQUENCY is the only variable.
2133mhz - stable, flawless.
2400mhz - stable, flawless.
2700mhz - noticeable jittering but tracking was fine.
3000mhz - bad tracking, errors, warping, ect.
Can someone from oculus please give some kind of explaination? My system is 100% stable and as Flexy123 suggested, I ran Aida64 with no issues, errors or loss of performance at full factory clock speed (3000mhz). Timing is not the problem, the Frequency is affecting my tracking.

Yes I asked him that..he didn't directly answer it but I assumed he did. (He pretty confidently said his system is stable).I also would be interested to know whether he can run 30-60min OCCT on "large" without problems. The thing is, XMP memory settings are usually not exactly hardcore overclocking settings, they are normally rather conservative.

Run OCCT with every RAM frequency to see if your system is really stable or not. Run each test at least 30 minutes or more. See here.

TBH...for me it's very difficult to see how changed ram timings WHILE THE SYSTEM REALLY BEING STABLE (ie: tested with OCCT, memtest etc.) would cause such problems.

Uhm..you didn't say what type/brand of ram it is...you only listed the board specs and what ram it supports. Would be interested what memory you have in there.

Update your Bios to F21, I have a Z170 motherboard and it's been piss poor until the latest Bios. It has had voltage problems all the way up to Bios version F21. Now my problems have gone but I'll continue to check.

The Rift software is looking for flashing lights in images. The camera is doing repeated DMA, many times a second, to big blocks of RAM through the CPU's memory controller, which is only rated to 2133MHz. May not take many memory errors to confuse the software about which pixels are flashing and which aren't.
And, oddly enough, it works fine at the frequency the CPU is rated for.
