Lowest tRFC timing on a DDR4 kit?

post #1 of 6
Thread Starter 
What is the lowest tRFC seen so far on a DDR4 kit?

Do you mean the spec or an overclocked setting?

tRFC greatly depends on volts.

Either or. I have a DDR3 kit, 3x2GB, that can do a very low tRFC timing, then I have a 2 8GB sticks that will not go lower than 208 @ 1600 So I'm kinda curious if there is a correlation between the amount of RAM on the stick and the tRFC timing.

I think it's more related to which ICs are on the sticks. And trying to compare the tRFC spec and capabilities of ICs based on 2 GBs vs 8 GBs is kind of like tying to compare the gas mileage of cars that seat 4 vs cars that seat 7 - there's a lot more to it than just the car's seating capacity (ie GBs of memory)

Same rule applies to DDR4, correct?
