Let’s take a look at my test bed, the trusty platform I’ve been testing lots of DDR2
Core 2 Duo E6300
First, 1 tried to see how well this kit can perform under tight latencies.
Thus, I set the memory timings to CL3-3-3-5 with 2.3v selected in my BIOS and
the system boots up fine and proceeded into windows.
Under this set of Fast Timing, I only managed to up the clockspeed for 5 more
MHz running 2.3v to 405MHz @ CL3-3-3-5.
In order to stabilize the clock speed at 410mhz at CL3-3-3-5,
I had to up the voltage to 2.35v.
