Abit AN8 Fatality and TWINX2048-3500LLPRO


Recommended Posts

I have just gotten TWINX2048-3500LLPRO for my Abit AN8 Fatality mb.


The problem I have is incredible instability. Since it is your recommended memory for that motherboard according to your configurator I am assuming that some setting must be changed?


Should I leave everything in the memory setup as Auto or should I use By SPD or what should I do. And should I go into my uGuru settings and change power for ddr modules or?


I kinda need help as my system was much more stable with my old worse memory than it is now with the new supposedly much faster memory.
