Performance @ Highest Overclock
For our next set of numbers, we focused on the maximum overclockability of Corsair's Dominator TWIN2X2048-8888C4DF memory kit while set to its rated timings. Using a Core 2 Duo Extreme X6800 CPU, we raised the Front Side Bus speed while concurrently lowering our processor's multiplier. We tried to keep the CPU as close to it's stock 2.93GHz clock speed as possible. For these tests, we locked the PCI Express clock to 100MHz, raised the CPU voltage to 1.35v, and kept the memory voltage to 2.4v.
When all was said and done, we were "only" able to bring the Dominator TWIN2X2048-8888C4DF kit up to 1158MHz, an increase of 48MHz. Had we relaxed the timings and applied more voltage, we likely could have gone higher, but we wanted to test a worst case scenario and 2.4v is already a relatively high voltage to be working with. While overclocked, we re-ran the SANDRA memory bandwidth benchmark and saw only marginal increases in bandwidth.
