Whats the focus on ram speed about lately?

Here's another site that found the same relationship between faster memory and better perf. in Fallout 4:

"Check out the sidebar concerning the impact of faster RAM: if you're running 1333MHz or 1666MHz DDR3, swapping that for 2400MHz RAM can make a substantial difference and definitely helps with your lowest frame-rates. We even saw substantial gains in CPU-bound areas with a Core i5 4690K."

Techspot also did their own independent test.

cpu-bound and gpu bound are two different things, higher speed ram in a cpu bound are will make a difference. however not many play games in this situation, most will have decent enough GPU's to be more gpu bound. no amount of extra speed for ram will help in a gpu bound situation. as well not all games are cpu dependent so we are pretty much cherry picking results to explain what we want to see with higher speed ram and increases to FPS.
 
Lol, thread (feels like it) starts with the same "vitriolic" tone as the other thread that was split off!!! :rofl:

I don't recall anyone here saying get the fastest you can get... we typically say 2800-3200.

Anyway, there are so few things that respond to faster memory, to me, there is little point in tweaking it. Only for benchmarking do I ever bother. A game, fallout 4, is responding nicely, but, who cares. It plays fine without touching the memory...and its one game of a few of hundreds, that respond well to memory overclocking.

There is also a guy around here, mackrel, that showed gains in prime95 if that is something you 'do'.

Still isn't "get the fastest you can find", it's "buy 3000MHz CL14 or CL15 and call it a day".
This. It's the sweetspot for price to performance in ddr4. Much less than that, read 2666 on down, is 'ddr3 speeds' but with higher timings, so why would anyone do that? 2800 cl13/14 or 3000 cl14/15, or even 3200 cl15 are all priced pretty close. Much above that is.a waste of cash.

That would depend... if its memory bandwidth/speed limited, then it would respond to faster memory speeds. Just being CPU bound does not mean that memory bandwidth is the limiting factor or would help.

"Some games respond better to a memory overclock then a CPU overclock", interesting were seeing the vram phenomenon in regular ram, it ranges between 5fps-20fps in some spots. Is this only with Skylake or can we get some more tests with other platforms to triple check this ?
