Faster RAM makes a difference in games
CPU cache - stock
CPU cache - 4ghz
That's a 10% gain. There seems to be this conventional wisdom that faster RAM makes no difference in games. I need to run more tests, but I really think I'm on to something here. There's also the notion that overclocking the CPU cache has no effect. I have a feeling that overclocking them both together made a difference.
I ran the test on my i5 4690k CPU with an overclocked GTX 1070 at 4k resolution with all the settings in the game maxed out, aside from the reflection AA which I left at 2x. I also left motion blur turned off.
Anyhow I just thought that was interesting. Food for thought for any of you guys still running Haswell systems if you have not tried overclocking your RAM yet. If you're going to overclock it, though, please be careful. I ran memtest overnight to make sure it was stable.
