The RAM will work at the same speed, usually the slowest. However you can always force it at higher rates, the slower RAM might just give issues sooner, just like when running them alone.

When you install the sticks, go straight to the BIOS and set them both to what the 800mhz ram is supposed to be set at. Then, overclock from there. If you can get them both at 1066 speeds, congratulations :cheers: Good luck!
