CPU to RAM relationssss

[Watashi]

What would be the reason not to get the highest speed RAM that my motherboard supports (asides from price) if any?

Besides price I can't think of any unless the fastest one was only slightly faster but had a higher cas latency by a significant factor, however you won't notice a difference unless the cpu is the bottleneck performance wise so price is important to consider

The only reason in my eyes (Apart from price) would be if you were COMPLETELY INSANE AND DIDNT BUY IT.

Aside from price, aesthetics. Also, overclocking. Generally, if you have high speed RAM, this can prevent your CPU overclocking from reaching its full potential. This is why many pro overclockers have setups where the RAM is actually underclocked. I myself don't run my RAM at its max speed.

Higher speed RAM won't yield you ANY real world benefit whatsoever (unless you're only running you iGPU since that performs better with higher speed RAM)

The only reason I'd caution against high speed ram is compatibility and stability. It isn't hard to find posts on things like that, starting around 3000 or so, depending on module and motherboard choice. If you get a set that works though, you wont look back in performance. As a compromise in speed and "it just working" I'm a fan of Kingston 2666 modules. They're generally competitively priced also.

What does cas latency stand for? and what does it do?

How does that work?

Essentially Its the delay for the memory to begin acquiring data it has requested, so the larger the cas the longer the delay which can lower performance just as slower ram could

High speed memory usually require higher voltage and put more strain to the IMC. 

Depending on you platform and particular CPU, it may limit your overclocking potential and may harm the IMC if the voltage exceeds safe parameters. (Happened with some Ivy bridge and DDR3 1.65V ram, quick google it). 

It becomes more of a problem in reliability systems, server side where you just can't trow a non JDEC kit because YOLO.

Thanks for explaining in my absence.
