I am planning on getting this motherboard in a few days and was wondering if it every Core Choke on it is ferrite, reason be hearing about rusting iron Core Chokes on Asus motherboards. I know that the ones around the CPU are ferrite but what about the 4 near the RAM slots 3 with "1R0" on them and the 4th thats blank one (black) that sits just slightly down from the the 3 are those ferrite?
