    Okay, a friend lent me 2, 2GB sticks of Buffalo premium RAM. I got some interesting but disappointing results.

    First, the Performance Test results were a better, but overall still underperformed compared to other machines with identical CPU/Motherboards (not taking into consideration over-clocked processors).

    Here are the CPU results:

    CPU - Integer Math: 1249.9
    CPU - Floating Point Math: 1919.4
    CPU - Find Prime Numbers: 700.0
    CPU - SSE: 7.1
    CPU - Compression: 4345.5
    CPU - Encryption: 12.4
    CPU - Physics: 137.3
    CPU - String Sorting: 1749.0
    CPU Mark: 3158.2
    PassMark Rating: 1358.0

    So it's better than before, yet still lower than comparable machines.

    Here's the graph for write results:

    Again, these look better than before, but perhaps not as good as they could be?

    And the Memory and SPD tabs in CPU-Z:

    So I haven't really changed the timing on the RAM. The sticker on it says CL5 so perhaps I could change the tRAS to 15?

    Also, my FPS is identical to using just 2 sticks of my KVR.
    About the ram timings, CL = CAS latency. The CAS spec is 5 and CAS shows to be at 5. The tRAS spec is 18 and it shows as being at 18 so there is nothing that needs changing.

      Are you defintely running on 4 cores. Also check the edit / preferences window in PerformanceTest. The PT result almost look like you only have 3 cores available. Each result is now almost exactly 75% of what I would expect the value to be. Where has the 25% gone?
      Yeah, I checked it. Number of processes = 4. I also see activity on all of the core monitors in the processes tab. I checked to make sure the heat sync was attached properly and my processor was clocked at the regular speed and it all checked out.
