New Ram and Configuration

[dgood]

So Some would say it's a waste of time to do this, but I am doing it.
I purchased a Mushkin 2x1gb kit of Cas 2 memory from newegg. I needed to get more ram so I figured why not get better ram for my main rig and use the ram from it to fill my other machines. As I needed more ram for my other machines. I had been just using some form one for multiple and eventually you run out of enough to have each running well. So I will be going from 4x512mb of dual channel cas 2.5 running at 333 and t2 timings due to motherboard limitation. Now I will be running 2x1gb at 400 mhz at t1 command rate and still dual channel. Will this be a noticable increase in performance? I just wanted to know.

Not a alot, but games and media encoding will the most due to lower latencies.
You'll only notice it in benchies really.

What might happen is, you might be able to OC more if the memory controller was your limitation previously.
