Let's start!
Yesterday I would to collect some data for the next Guidemania version.
Thus I tested again the old Kingston HyperX
RAM module.
I spent almost two hours so I put back the Mushkin
RAM modules and GKR GKR

GKR GKR

system crashed...
It could not pass single SuperPi 32M (it crashed after 2-3 loops)...
I did not change any settings (I set the same as I do)....
Therefore what was going on??????????
