If I have read your links correctly then you are trying to use a 32Gb Kit of 1866MHz RAM Modules with a Sandybridge i5-2500k CPU.
If this is right then you will probably have to change your settings in BIOS to get them to play nicely together.
Make sure that the RAM is set for 1333MHz and double check the timing figures. You can loosen the timing figures a little from their default setting of 8,9,8 to 9,9,9,24,2T (this is a guess on my part but is a good starting point to work from) as this may help with system stability.
You may also need to increase the RAM voltage slightly from the base level of 1.5V to get all 32Gb running sweetly. Don't increase the voltage too much in one go try increasing by the minimum amount that the BIOS will allow, test, and then add another small amount if the system is still unstable.
