Bad performance on High End System? (bench)

Hello, I am running a rig with the following specs and I used 3D Mark11 Basic to bench it. It concluded that my system was performing badly compared to similar systems. Basically, why would it be saying this, and what is the problem? If you need any more info, please let me know. Thank you all ahead of time.


i7 2600k @ 4.5 GHz
Noctua HSF NH-D14 (stock fans and paste)
3x2Gb DDR3 1600 XMS3 @ 1333Mhz (CMX6GX3M3C1600C7)
500gb 7200rpm Hitachi
GTX 580 Super-clocked (factory overclock)
Zalaman 1000w PSU

3D Mark Basic Results:

3DMark ScoreP6839
Graphics Score6559
Physics Score8677
Combined Score6856
GraphicsTest128.66 FPS
GraphicsTest229.87 FPS
GraphicsTest342.16 FPS
GraphicsTest420.76 FPS
PhysicsTest27.55 FPS
CombinedTest31.89 FPS

Side Question: For whatever reason, I know I have my CPU OC'd to 4.5Ghz stable, but in device manager it says "i7 2600k @ 3.4ghz (stock)." Why would it be doing this?

  1. I don't see any obvious reason why your system would be running slower than similar systems... Never really used 3DMark11, though

    Shouldn't make that much of a difference, but why is your 1600MHz memory running at 1333MHz?

    Run IntelBurnTest on standard and CPU-Z, that'll tell you the real frequency of your processor. Might want to check HWMonitor as well for your temps and voltages, at the same time...
  2. Your memory running at 1333 MHZ will make no difference to real world performance at all. This has been proven time and time again. That HDD is a little slow for that system it could really use a SSD.
  3. I have a ssd. I didn't run the test on it though, so I felt no need to include it. It shouldn't make that big of a difference though.
  4. What are you running in the background? What other programs are running at the same time? 3DMark11 needs to be the only program running or it will tell you that your system is performing below par.
  5. Ok I ran a bench using passmark and this is what I got. I feel as though this should be about right. Tell me what you guys think.

    CD - Read: 2.6
    CPU Mark: 11265.0
    2D Graphics Mark: 671.7
    Memory Mark: 2279.0
    Disk Mark: 447.6
    CD Mark: 313.9
    3D Graphics Mark: 4397.8
    PassMark Rating: 2294.4

    in response to the CPU, i have it OC'd on turbo multiplier shared by all cores that is adjustable by the OS. it seems to read 3.4 GHz in passmark but wouldn't it just ramp up to 4.5 GHz when the CPU is being used?
  6. Like I said before, if you only want to test your CPU:

    Run IntelBurnTest
    Check max VCore and Frequency on CPU-Z
    Check other voltages and CPU temperatures on HWMonitor

    IntelBurnTest really stresses your CPU and generates A LOT of heat. Nothing should make it get to a higher temperature.

    Maximum temperature you should reach is 80Celcius. However, Sandy Bridge starts to throttle at ~94Celcius.
