Here's a few things to think about when you want to improve your gaming experience through storage speed boosts.
First, it doesn't matter a whole lot in most multiplayer games. Games like StarCraft, CoD, BF, etc can't start until everyone is loaded up. So you won't get into the game faster because you still need to wait for others to load and also for the server to sync everyone. The exception to this is MMOs when you're loading a new zone. Even then, you're going to have limitations in how fast this can happen due to the game itself.
Second, some games are hard coded in how long they load. Opening logos, videos, splash screens, etc, can't always be skipped. Mass Effect 2 had loading animation videos that had to play through at least once before it would move on. That meant even though I had it on an SSD, I didn't see any benefit when loading save games until I modified the game and took out the videos ( then it would load maps and save games in 1 - 2 seconds ).
Finally, realize the limits. Yes, a RAM disk is much faster than a SSD in terms of benchmarks. But sometimes the user doesn't actually notice or appreciate the speed differences because we react so much slower than computers do. You will quickly reach the point when you spend a lot more time, effort, and money than it is worth to get everything as fast as it can possibly be. And the actual speed benefit may not be a whole lot better than what a cheaper solution provides.
If you want to speed up the RAM disk, you'll get better bandwidth and response by optimizing the RAM frequency and latency timings than you will see by speeding up the BCLK alone. However, loading programs off a RAM disk is already insanely fast at stock speeds, so don't expect a noticeable difference.
