Help building an AMD system

[Tetras]

I guess the question is what are ocuk advertising things as, mhz, sticks that won't run at statedted mhz, or not?
My corsair rgb vengence don't run at 6000, but I'm not that bothered right now because they run at 3000mhz happilly, and I paid a lot less for them from somewhere else that you would need an umbrella to walk around in

I would say that they just copy paste the manufacturer, but Corsair actually use both. For example, they describe the SPD speed as 4800 Mhz (incorrect) and the rated speed as 6000 MT/s (correct) in the same product page
