here is a screen shot from a P5NT-Deluxe >>>> yours should be similar
first step is you need to change that memory setting to "manual" then set it to 1:1
in the future if when you add your cpu cooler, if you overclock any higher I would advise you "unlink" the cpu / memory this will overclock only your cpu not your memory in unison, because DDR2-800 memory will get alittle flaky after 860mhz some say DDR2-800 will go all the way to 900mhz, but I havent seen that myself yet; without some burned up sticks within a couple of weeks anyway
