i did research your sticks the 2x2gb ones(Wintec) and they seem to run on the RATED 1066mhz speed..have you updated the BIOS of your motherboard??
here's a link to the BIOS support page for that BOARD the Foxconn A79A-S
that is the EPP(Enhanced Performance Profile) a specific table/setting for your memory to perform the OPTIMAL way..it carries the timings and Voltage settings..
