Best RAM for APU? (Latency/Frequency ratio)

Doing research on APUs and the effect of RAM on them, I've read and watched multiple videos that state lower latency and higher frequency is the best. This led me to the question, which configuration would be most effective?

in theory I believe I could go towards lower latency, and make up for the frequency by using up all 4 slots. (I'm not even sure how this would work out, since it'd still be dual-channel).
In practice, 4 x 4GB modules of 1866 w/ 8 Cas would be better than say, 2 x 8GB 2133 w/ 9 Cas.

That's what I understand so far, but this is likely wrong so I'm turning here hoping for someone to clear this out for me. Also, I noticed some modules have higher voltage than the average ones (1.65v) is this something to worry about?
I'm not an expert, so please excuse me if i got any (or many) of the concepts wrong. Thanks.

For system usage, lower latency is better. But for graphics (APUs) higher frequency is better. If you can have both is much better.

Look for 1866MHz or 2133MHz with CAS 9 or 10 (even 11 is OK) and you're ready to go. Use only 2 modules (2x2GB, 2x4GB or 2x8GB), is more stable than 4 modules (AMD IMC could lower the speed of the RAM with 4 modules in some cases).
