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.

System Setup

Windwithme got his hands on Intel’s latest CPU and spend several days checking out its performance and to see how far he could overclock it with an air cooled heatsink.

The Core 2 Extreme X6800 has 4Mb L2 cache and comes clocked at 2.93Ghz. The FSB is 266 (quad-pumped) x 11 (multiplier) giving an effective 1066Mhz FSB.

Can you tell which one is which?

On the left side is the Core 2 on the right a Pentium D 950 C1

I used a MSI 975X Platinum 2.x (most important difference with version 1.x is support for Conroe CPU)

Corsair TWIN2X2048-6400C3 DDR2 800 CL3 4-3-9 (with support for nVidia’s EPP)

The Cell submenu allows you to control most important options

The FSB can be increased all the way up to 425, which would translate into 4675Mhz CPU clock speed with multi 11x; so there’s quite a bit of headroom.
