hey guys which ram slots are you using (color) when your overclocking your ram? I have mine in slots 1 and 2 (based on the 1-4 counting scheme) and i cant overclock my ram for the life of me....nothing at all...cant tighten timings, cant push to 900 with suggested timings from mushkin (that are supposed to give me clocks of 1000mhz) or anything
