AMD Phenom II X4 940 Review

» Discuss this article (14)


I am so excited to finally begin testing the new AMD Phenom II that I cannot contain myself. Do I have you amped up also? To test the Phenom II X4 940 I will be running a series of scientific and video benchmarks designed to push the processor and hardware to their limits to score the performance. Then I will be comparing the Phenom II against other processors new and old to give you an idea of where it sits on todays market. Just a note for the video benchmarks - only the Intel Q9450, AMD Phenom X4 9850 and the Intel i7 965 will be included in the comparison because of the new video benchmarks OCC is using. To keep down any variables from interfering with the scores, all hardware will be run at their stock speeds, timings, latencies, and voltages.

Overclocked settings:

  • Processor: AMD Phenom II X4 940 @ 3.755GHz (200x18.5) 1.55v
  • Sytem Memory: Mushkin Redline PC2-1000 @ 818MHz (5-5-5-15)

To overclock the AMD Phenom II X4 940 I started with the multiplier since this is a "Black Box" Edition with an unlocked multi. I pushed the multi 1x at a time until the system would not boot or became unstable. Then I backed it down by a half to achieve stability. Next I pushed the BUS speed 1MHz at a time until again the system because unstable. Doing this gave me a nice stable overclock that passed all of the benchmarks with no problems at all. The final overclocking result was 3.755GHz which is about a 26% overclock. This is also 155MHz better than my first run with this processor when I attended the AMD Tech Day.
