I have been running some tests to see how RAM speed can affect games on my 4930k setup.
It will probably take a couple more days for me to complete the tests and post my findings, but I wanted to get some feedback on what others think the results will be.
I am testing stock and overclocked CPU speeds as well as tightening up the RAM timings from what it defaults to at each speed.
"Stock" CPU speed will be locked at 3.6Ghz since it gives more repeatable scores compared to leaving it on auto turbo.
Overclocked CPU speed is 4.7Ghz.
RAM speeds are being tested at 1333, 1600, 2133, and 2400. If I get requests for it I can add 1866 as well.
Video card setup is 2x AMD 7970s running at 1150/1575 - changed to 1120/1575 due to texture flashing in Unigine Heaven Benchmark 4.0.
8/18/2015 - I now have an ASUS R9 390 that I will be testing as well. The tests with the 7970s will be posted before I run the tests for the 390.
8/31/2015 - Driver version is 15.8 beta. (Had to restart from scratch due to Thief crashing almost all the time with 15.7.1 with Mantle crossfire enabled with MSI afterburner running or Overdrive enabled.)
9/4/2015 - The test suite so far is as follows:
Unigine Heaven Benchmark 4.0
Unigine Valley Benchmark 1.0
CatZilla 1.4 - nix this unless somebody knows how to get it to run in Windows 10 without hard locking the whole system while installing or when running it.
3DMark Advanced
S.T.A.L.K.E.R. Call of Pripyat Benchmark
Lost Planet: Extreme Condition Demo (DX10 version) - not sure which on [H] used - http://www.gamershell.com/news_41664.html
Lost Planet 2 Benchmark - http://www.geforce.com/games-applications/pc-games/lost-planet-2
Bioshock Infinite
Batman Arkham City GOTY
Dirt 3
Dirt Showdown
Thief
Tomb Raider
I am only running canned benchmarks for the sake of more consistent results and because I really don't have unlimited time to dedicate to this.
This came about because of the review of the i7-6700k showing that RAM speed can affect game engines on that setup.

Tests will be done in 1280x720 and 1920x1080 as well as the lowest resolution available.
This guide was helpful for figuring out what all the different RAM timing settings are and how they relate to each other.

The following is the information on speed/timings for the RAM I will be using for these tests.
I will add and reorganize the different speeds/timings as I get them figured out.
