In a perfect world the mobo would lower the clock speed to match your slowest memory, I would try it with just the new sticks, then try it with the old sticks, the old sticks would most likely work, when you buy memory its important to make sure it matches.

Reinforcing what PapaWood said, the manual (available in the Tech support portion of the page that was linked) they have the following: "It is recommended that memory of the same capacity, brand, speed, and chips be used and please select dual channel first to achieve optimum performance."

Typically MBs can support slower memory, but not faster without OCing the memory controller, so even if you use a different brand of memory, you cannot exceed the max the board supports.

Gotcha, hrmmm. does the BIOS recognize 6bs?

Personally if it as me I would return the new memory and get the correct speed, really ideally both of those sticks should be identical, same size, same speed same timings, even more same brand same model same everything.
