questions about ram frequency and timing

I have two different RAM kits. One is 16gb gskill ripjaws X 1600 9-9-9 24, 1.5v and the other is 16gb Corsair Vengeance Pro 2133 9-11-11-31, 1.65v I was wondering which one I should keep. I don't know a lot about RAM frequency and timings so if someone could explain which kit will give me better for performance I would appreciate it. If it heps my PC is OC'd to 4.7 and passed 6.45 hours AIDA64 and 8 hours ETU But crashed after 45 min prime 95 blend test.
 
For speed , bigger is better / for CAS lower is better.

Some apps / games benefit little for better stuff.... others show significant benefit. In gaming, going from 1600 to 2400 for example can be boost fps by a fraction of a % or 11+ % depending on the game.

On new builds I usually use 2133 if user's budget restrictions keep him / her from 2400 .... (but this week, 2400 is cheaper in some instances) ..... in short.... keep the 2133 :)

To maintain the 4.7 OC on XMP profile, ya may need to bump voltage to 1.7 ... and no this is absolutely no concern whatsoever.

In the Haswell / Devil's Canyon age, it's time to forget about AIDA, P95 etc.... you can be stable in all the synthetic benchmarks and then fail on an application based stress test like RoG Real Bench.

4790K and Maximus VII Hero, I currently have it at 1866 8-10-10-27 and memtest gave me no errors. I may try and see how low I can get the timings at 1600.

 
Not sure why you are trying to run slower... ?

As you cane see here.... running at a slower speed and lower timings most often results in a decrease in gaming performance

I see what you mean but I was worried about stability while running at rated speeds. I could easily put the RAM back to rated speed. I dont know how the best answer got chosen but you have all been a big help and thank you to everyone who replied to this post.

That's good for 1866, but no need for trying at 1600, no need to even drop from 2133 to 1866, the wider bandwidth is better
 


If it doesn't run at rated speeds you send it back and get a replacement :)
