While on the P55 platform 2000MHz DDR memory worked great due to our divider choices, and 2133MHz was a bit of a pain due to having to tweak extra settings, the tables have really turned on the latest Intel chipset. We've mentioned already a number of times, including in our OCZ Platinum XTE review of the 2000MHz DDR kit, because of there being no divider for 2000MHz DDR you have to adjust the very limited BCLK. What it ultimately means is a bit of a hit and miss experience with 2000MHz DDR memory. If it's good overclocking RAM, you'll be ok. If not, you could struggle to hit the default clocks due to the limited option in the BIOS.
