G.Skill PC2-6400 Memory
 

The G.Skill PC6400 modules ended up running at up to 975MHz at 4-4-4-12 timing - that is 175MHz above the rated 800MHz speed; a 21.9% increase in raw memory clock rate. We have seen higher memory speeds, but it is still fairly impressive to see a PC6400 module reach PC7800 speeds.

In order to reach 975-4-4-4-12 stably, I had to increase the memory voltage to 2.35V. The modules were quite warm, but they were not too hot to touch, however even increasing the memory voltage to 2.4V did not get them stable at 1000MHz. I was using a 1.45Vcore, 1.65 Northbridge, 1.45 FSB voltage setting.
