No. Some boards default to 1066, but 1600 is easily doable by simply changing one bios setting, overclocking the cpu, or both. Not much difference in price either. All my 1333 ddr3 runs at 1600 if you find some cheaper. I currently have 3 different brands.
Thanks o1die, What BIOS setting could i change that wouldn't require an aftermarket cooler yet still be able to run the memory at 1600? From 2:8 to 2:12?
