RAM: Mhz vs. Latency

[droid]

What would you choose?

DDR3 2400 at CL11

or

DDR3 1600 at CL7

Are you looking to do benchmarks? Cause other than that there are very few reasons for this kind of RAM, most of which I dont think you'll be doing at home

But if I had to choose..... Well it depends on two more things - brand and voltage. Some brands seem to overclock better (in my limited experience), and lower voltages also mean its easier to overlock. Both of which could make the 1600 CL7 a better contender

Thanks for input.
Just a general interest.

It really depends on the system in question. I'd choose the higher-frequency stuff if it was going in a APU build (would actually prefer DDR3-2133 because most FM2 boards can hit that), or the low-latency stuff if it was going in an Intel build. For the most part the higher frequencies aren't noticeable in many workloads and the price mostly puts me off buying any of the expensive kits - the higher data rates can't be justified in terms of what I'm paying for them.

Of the 2 kits that you linked I would go for the 2400CL one because I have LGA 2011 and my system would be able to use it.
However in a LGA 1155 Sandy CPU PC, I would get the 1600C7 kit.

Both are important, and you will most likely find that those 2 kits perform similar overall, with the certain programs favoring either higher speed or lower latency and that particular test that ram would be faster.

For Intel I would go for a 2133 CL 8-8-8-24 kit and for AMD I would try to get a 1600 CL 5-6-5-18, or something in that region.

The AMD FM2 stuff can puch Mhz upto 3000 so the 2400 would get my money.

So depending on your Socket you will note that from 1600C9 to 2400C9 there will not be that noticeable Difference. And that leads me to get whichever is cheaper.

EDIT:
By the looks of those kits you are looking at the Corsair Vengeance 1600C7 RED kit or the new Team extreem 8GB 2400C11 Kit. Get the Team RAM, you should be able to push the latency down a lot when only running at 1600 on those sticks. I remember the old OCZ reaper could get 1600 C7 out of the 2000C9.

If you're just going to be building a decent gaming rig and not a very high end one, you may even want to consider getting the cheaper DDR3 1600MHz CL9.

Awesome info, thank you all.
