My Bios shows my current frequency as 1333Mhz even though I purchased a 1600Mhz.
I am completely new at doing these sorts of things and I was wondering how I can change the frequency back to the regular 1600.
there two things you want to do. first off check the bios rev on the first page of the sabertooth bios page. the newest bios is 1504 the shipping bios was x800. there been a few bug fixes. what you want to do is download the next bios file above the one your mb rev. then rename it z77st.cap. copy it to a usb stick if you dont have a usb stick leave it in download or my doc.
wit hthe usb stick power off the pc and put the usb stick in the usb flash back port and press the usb flashback button. it flash for a few min if the file is named right and then turn off. update the bios that way till new bios 1504 is installed. if you dont have a usb stick go into the bios and under advace mode is a bios flashing program.all you need to do is point on the hard drive where the z77st.cap file is.
for the ram under the ai setting for ram speed change the dram speed from auto to xmp. the mb will read your ram spd info and reset itself. to 1600.
