so ur asking what kind of ram u can use?Just trying to clairify the overclocking denotation behind all the ram speeds on the mini itx boards they have 10 or so different ram speeds all but two show [oc] behind them. when I look up ram available none of the manufacturers refer to a ram speed with [oc] in the description I know what overclocking is generally but is all this info with the motherboards just for gamers who intend to overclock a cpu to fit a specific game quality? I guess for me the question is what is the fastest ram speed for day to day operations using three monitors and some Rebit software. I already have 1866 corsair sticks but the motherboard says 1866[oc] does the cpu have to be run at higher than 3.4 MHz to get ddr3 1866ram to run at 1866 that is my confusion.by the way sorry for the wrong motherboard form factor the one I have is mini itx. not micro atc that could be a very small three wheel motorbike.
