I was told (by memory tech guys) that if you use both sets of ram slots on a motherboard, you risk having any speed over 1333 or latency under 9 9 9 9 24 to get reduced to spec or other issues. That it varies per the board, not the brand.
Is this true? How concerned do I need to be about getting for example 1600 ram only to have it reduced because I am using all 4 of my slots?
If you reply with a answer, please tell me if your speaking from specific knowledge, or more of a educated guess.
