    Why is my Aorus X7v2 underperforming?

    My brand new Aorus X7v2:

    - i7 4860HQ @ 2.4Ghz (Average benchmark of 9382 @ cpubenchmark.net)
    - 32GB DDRAM @ 1866Mhz
    - $3349AUD

    Seems to be performing poorly on the QwikMark benchmark:

    - CPU Speed: 2.39... GHz
    - CPU FLOPS: 34 Gigaflops
    - Mem Bandwidth: 7GB/second

    This seems poor because by contrast my colleague's several-months-old Dell Inspiron 15 7000:

    - i7 4500U @ 1.8Ghz (Average benchmark of 3849 @cpubenchmark.net)
    - 16GB RAM
    - ~$1800AUD

    Significant outperformed it:

    - CPU Speed: 1.79.... GHz
    - CPU FLOPS: 68 Gigaflops <-- what the???
    - Mem Bandwidth: 12GB/second <--- WHAT?????

    What's happened???

    a) Is QwikMark not a good benchmarking tool?
    b) Am I misinterpreting the results?
    c) Have I bought a dud?
    d) Does the Aorus X7v2 have some performance gotchas I didn't realize?

    P.S. I'm running Windows 8.1 with latest upadtes in full performance mode with nothing else running

    QwikMark is an unknown benchmark. Try to do a real bench like Cinebench 11.5, wPrime, or x264 benchmark. These will give you real results, and you will see the quad core result in 3-4 times that of the ULV CPU.

    Also make sure you're not running the test on battery, and that your power profile is set to "high performance".

    Here's the result of my i7-4710HQ

    Thanks for the response.

    Following some further windows updates earlier I am getting good performance & can confirm overclocking kicks in:

    So it must have been a driver update or windows update that fixed it. (I was on power before & full performance.)

    Out of curiosity what is your i7-4710HQ result on any of teh benchmark tools you used?

    To add to the mystery though.......

    I ran the benchmark after an hour's gaming and got great results.

    Now I ran it after a reboot and the benchmark is back to crappiness - no overclocking.

    I can see from a monitor tool, by feel & from the low fanspeed that it isn't overheating now.

    How does Windows or the chipset decide when to allow overclocking?

    SOLVED


    In COMMAND & CONTROL, I had set the FAN TWEAK to be SILENT instead of AUTO.

    Switch back to AUTO gave me all my Ghz's & Gigaflops back and running at 100% capacity again.

    Makes sense... The CPU+GPU would throttle to keep temps acceptable with the lower fan speed... Good to see your beast performing well again :)
