Yes. The ram speed may default to a lower speed initially, and require you to set it in manual mode in the bios. Check the post screen for your ram speed. If it runs at 1333, press the "del" key before the post screen disappears, or reboot and start over. You should have a setting for "auto" for the ram in the chipset section or advanced section of the bios somewhere, unless your board is made for dell, hp, etc. They generally don't allow you to change the ram speed yourself.
