Before buying the RAM kit, I searched online for reassurance that it would work okay. Couldn't find it (obviously this RAM is not in the QVL list) so I took the risk and bought it anyway. Well… all good: my system is stable with Expo enabled, so I am happy.
Clearly this is not overclocked (in particular I am disappointed by the 73ns latency reported by AIDA, which is higher than my previous memory kit, despite it was CL40, don't really know why), but I am posting here mainly to help others who may be looking for the same reassurance.
Does anybody with a similar combination have any suggestion to reduce latency?
