Trying to choose DDR-III Memory Modules for 32 GB RAM (4 * 8 GB)

[AMDforME]

You may want to check your owner's manual as the specs for the ASUS M4A785TD-V EVO show that it only supports up to 16GB. of 1800 MHz. DDR3 RAM. 16GB. is more than most people will ever use unless you are running a RAM disk or have software that can actually use more RAM. You should also check the O/S that you are using to be sure it can use 16GB. of RAM.

1600 MHz. DDR3 RAM is all that is needed for a typical desktop CPU but for an APU then up to ~2133 MHz. shows modest improvments. Your mobo may or may not be able to support much higher than 1800 MHz. depending on the CPU and RAM used but you would have some reserve for a future upgrade. As far as performance there is no tangible system performance gains on a desktop CPU running RAM above 1600 MHz. with real apps.
