what kind did you apply..?? regular white..? or artic silver..?? Also how did you apply the grease on the ram and stick the sinks to it..? did ya clamp them on with metal..? If you put ram sinks on the best easy way to do it is frag tape. Not sure how ya put the sinks on with just grease. If it was artic silver then ya probably put on to much and it connected some of the ram pins.
