why do almost all micro atc motherboards publish the ram compatibility with [oc] after the ram speed except for the last two slowest speeds does this affect anything to someone who is not overclocking the cpu I have not found any ram being sold as 1866 [oc] ram or any other [oc] advertised speeds. does this just refer to capability with over clocking and will have no effect on normal user applications. I just need a micro atx mobo preferably asus with the z87 or 97 onboard chip to fit my build the fastest corsair ram possible would be great also.
