Question If my motherboard specs say it only supports 800Mhz RAM speeds, does that mean that installing a 1600Mhz stick of 8GB ram will result in half speed?

According to PC Specs, my Acer TC-605 only supports up to two sticks of RAM and 32GB of RAM total. It also says that it only supports up to 800Mhz of speed. However, it is unclear to me if this means it only supports 800Mhz total from both sticks or from just one for a total of 1600Mhz. If I were to install a 1600Mhz stick of ram, would it just use half of that? I only ask because my current stick is 8GB @800Mhz, and I can't find similar RAM at all. Would I be able to install new RAM at faster speeds and be ok? Or would my PC not start at all?

DDR3 - Dual Data Rate generation 3
the keyword there is DUAL.
the RAM is rated at 1600mhz because each of the 800 cycles per second is able to send AND receive every clock cycle. the effect is that DDR3 800 is rated at 1600. it can be a bit confusing
my DDR4 3000 runs at 1500
your DDR3 1600 is running at its specced 800mhz

That makes so much sense. So I would be fine with two 16GB sticks as long as they're DDR3? I know I really should be looking for DDR4 Mobos at this day-in-age, but I'm currently taking baby steps as I don't have the money to buy many parts at once.
