@Viper.Br - good going. if your now stable, you might try tightening memory timings:-
CAS# Latency: 5 ---> 4
RAS# to CAS# Delay: 5 ---> 4
RAS# Precharge: 5 ----> 4
RAS# Activate to Precharge: 15 -----> 12

or

Select 3:4 divider (Dram Frequency) (=1101) with the timings as is

won't give you a big bump in real world applications, but gives a little extra tweak. This means your meory is slightly overclocked, being rated at 1067 If it's not stable at that vdimm at 2.25v should stabalise it, though you will need some active memory cooling.
