Intel Quad Core Q9300 Goes Subzero - OC Fun

Overclocking/Overclocking Tests by massman @ 2008-05-02

Our previous overclocking review with the Intel E8500 was quite a success; we were allowed this time to push an Intel Q9300 ES to the limit using sub zero cooling. This CPU comes straight from and is the most affordable Intel Quad Core build on 45nm.

Introduction & Test Setup

Intel C2Q Q9300:

The Q9300 was released a few months ago and has been updated a few times since. The series started out with the C0 stepping, moved on to C1 and recently, the M1 stepping has seen the daylight. It seems that the newer stepping have a higher overclock potential, however, higher overclocks are not guaranteed as the good C0's are still doing at least equally good compared to the average M1 stepping.

Our chip has been tested and compared to the Phenom X4 recently here and afterwards, we were allowed to push it under a subzero cooling machine.

Thanks to, we managed to lay our hands on an Intel Q9300 processor.
