The Youngest of Yorkfields: Intel Core 2 Quad Q9300 Processor Review
Numerous overclocking experiments show that the maximum FSB frequency contemporary mainboards can reach when working with quad-core processors and traditional cooling systems is 460-470MHz. That is why the typical overclocking result for Core 2 Quad Q9300 will be around 3.4-3.5GHz. Further frequency increase will be limited by the mainboard and the chipset, but not by the CPU that can definitely do better.
For our experiments we used the same testbed as described above with ASUS P5E3 Deluxe mainboard on Intel X38 chipset. The processor was cooled with Scythe Infinity air cooler.
The obtained result falls precisely into our theoretical assumptions. Our system with Core 2 Quad Q9300 processor remained stable at maximum 467MHz FSB. As a result, we managed to overclock our CPU to 3.5GHz.
