I have an Asus M4A785TD-V EVO Motherboard. Considering this, What happens if I plugin 2 ram chips of different frequency and different latancies? Do both work independently at their respective configs or both have to sync at lower performance ?
That motherboard should automatize individually each slot, so there shouldn't be any stability problems. Although it's not recommended and you can forget overcloking with that setting. Both memories will work at the slowest frequency. Maybe you'll have to tweak the voltages a bit if they are different.
