what did you bump your VCCIO to. I'm having issues getting mine to post if i bump VCCIO
with 4 sticks of memory I was able to boot up to 1867MHz using default (auto) VCCIO at 1.058v.
at 2133MHz I needed a slight bump however for firmer stability when under load, settled it at 1.100V and all works fine. I read that some users actually needed 1.200V (which is probably close to safe daily maximum you can set it to), I tried that first but there was no difference between this and 1.1v.
Mind that I am new to this technology and actually I don't know if maybe I am supposed to run the VCCIO at 1.15v so it stays 0.5v below the DIMM voltage (1.65V)... but then again maybe that was the case on P55 and not on P67/Z68, I am not sure, still learning this stuff.
EDIT:
eventually I set VCCIO at 1.15V, because I had some random fail errors under LinX even at first pass.
Now I am stable under Linx 0.6.4 w/AVX for 20 rounds in Max memory mode, with CPU @ 4.5GHz (x45 multi) using vcore of 1.325v and the memory running 2133MHz (4 sticks, 4GB each, 9-11-10-28 1T @ 1.65v).
the only thing which keeps bugging me is why I have to use automatic Command Rate on memory and manual setting (same value as auto!) doesn't work at all resulting in POST code 45.
