I have 20M errors on mem if I pass 2125 on my samsung 584, and the cards sits 32,5mhs
Tried your suggestion regarding core, @1180 i get 0.7mhs more then on 1150~60
You are the first that proof the big increase that i was telling with core and rxboost :-)
Because of your mem errors your strap i bet yourstrap is to tight,i run 2150 without any error up to 2200
