Sterotypes that High Speed Rams donot affect gaming performance are gone. 2400mhz vs 3200mhz in some games are getting 10fps more and min fps increases across the board.
As such I ordered the below rams for my upcoming build upgrade. Overall you have a smoother frame pacing. Wasn't a big deal back in the DDR3 days, but yeah, these newer CPUs on a DDR4 platform loves faster RAM.
Higher the frequency the more diminishing returns on tighter timings. The higher up you go on freq the less impact latency has.
DDR4-3200
@CL16
16 * 20 / 32 = 10
@CL19
19 * 20 / 32 = 11.875
DDR4-3000
@CL16
16*2 / 3 = 10.67
@CL19
19* 2 / 3 =12.67
Latency refers to the delay that occurs in data transmission as data moves between computer RAM and the processor
