I have 4x8 3200mhz sticks that are showing 1500mhz in task manager. The ram was purchased in 2 different kits (I purchased 1 kit of 2x8 a year after I purchased the first kit of 2x8). All four ram sticks are the exact same with the same timings and voltages, except the speed seems incorrect. Shouldn't it be showing up as 3200mhz in task manager if I set it up that way in the BIOS? I have an AMD processor and no XMP mode. Also, in CPUZ it shows up as me having a dual-channel, but I'm using all 4 slots. Shouldn't it show up as quad-channel or multi?
