Intel Core 2 Extreme X6800 Overclocking with Air Cooling

Overclocking/Overclocking Tests by windwithme @ 2006-06-19

With the release of Core 2 from Intel approaching we take a look at how much headroom the X6800 (Extreme Edition) has left, clocked at 2.93Ghz we push it to the limit using high end air cooling.

Overclocking over 3Ghz with ease

Not all software recognizes the new CPU but there were some which did, the latest version of Everest correctly identified the Core 2 model, a prerelease version of GCPUID got the model correct also but the multiplier and FSB values are off, CPU-Z (at first) displayed incorrect vcore and CPU speed and qualified the CPU as Core Duo. After the first tests a new CPU-Z was released this corrected these errors.

Using SuperPi, PCMark05, Everest and CPUMark99 I got the system base performance before I started overclocking.

The Everest CPU tests display the system’s score compared to other popular configurations:

First overclock – E8000 speeds

Without adding vcore the system ran stable at 300Mhz FSB which results in 3300Mhz CPU speed, and this is the rating of the Core 2 Extreme E8000 model which Intel is planning to release at the end of this year.

Next up: trying to find out the maximum FSB this CPU and motherboard combination could obtain, the CPU multiplier was reduced to 8x and got up to 390Mhz FSB, impressive!
