Speed or latency?

[Randpost]

I have been messing around with a 4x8 sticks of Corsair RGB DDR4 3200 C16. I found that 2 of the 4 sticks are much better at overclocking than the other two .

I was able to hit 3700mhz with some decent timings @ 1.35v 16-16-36. I was also able to hit 4000mhz but I had to feed 1.4v and increase the timings drastically to achieve 4k.
Just like the title says, would you go with speed or timings? I'm on the fence with using 1.4v for every day use.

3700mhz



4000mhz

1.4v is fine. Don't know what mobo you have, but you very likely aren't getting as much voltage to your RAM as the software claims. I went back and forth between speed/latency/voltage for a week trying to nail that Golden combo. I ended up with what's in my sig. You can try bumping up your cache speed, too. And check your VCCIO and SA voltage to make sure you aren't using more vDIMM than needed. I'm running 4400 MHz cache (uncore) and 1.2v on VCCIO and SA (Sytem Agent). Runs like a champ.

3600-3733 at CL16 and not so high voltages is about the best as Alaric said.

I did bump my tRFC up to 530 from 275 recently. Internet Explorer started acting strange and not knowing if it was early signs of corruption from the RAM OC I figured it couldn't hurt. Haven't noticed any negative results from it. For typical day to day usage you can't tell 3200 MHZ 14-14-14 from 3733 MHz 16-16-16 anyway. Once you get past 3200 14-14-14 it's all bragging rights, because you start running in to other systems' shortcomings in overall performance. Weakest link and all that. It's still fun, though.
