    Problems explained (sorry for poor quality)

    I have just built my new Workstation and I'm experiencing several problems. I'm getting a lag in Premiere Pro, high pitched buzzing noises coming from all over my case and very poor results when benchmarking. See below for scores.

    My Build: PCPartPicker part list: http://uk.pcpartpicker.com/p/jhCnrH
    CPU: Intel Core i7-5820K 3.3GHz 6-Core Processor CPU Cooler: Noctua NH-D15 82.5 CFM CPU Cooler Motherboard: Asus X99-PRO ATX LGA2011-3 Motherboard Memory: Crucial 32GB (4 x 8GB) DDR4-2133 Memory Storage: Samsung 850 EVO-Series 250GB 2.5" Solid State Drive Storage: Western Digital BLACK SERIES 1TB 3.5" 7200RPM Internal Hard Drive Storage: Western Digital BLACK SERIES 2TB 3.5" 7200RPM Internal Hard Drive Video Card: EVGA GeForce GTX 970 4GB SSC ACX 2.0 Video Card Case: Fractal Design Define R5 (Black) ATX Mid Tower Case Power Supply: XFX XTR 750W 80+ Gold Certified Fully-Modular ATX Power Supply Operating System: Microsoft Windows 8.1 (OEM) (64-bit) Case Fan: Noctua NF-A14 PWM 82.5 CFM 140mm Fan Monitor: Dell U2515H 60Hz 25.0" Monitor
    Realbench results:

    Image Editing: 79808 Time: 107.507
    Encoding: 111448 Time: 107.565
    OpenCL: 60660 KSamples/sec: 1462
    Heavy Multitasking: 64760 Time: 151.019
    System Score: 67037

    Have you installed all the motherboard drivers as well as component ones?

    Are the buzzing noise electrical or physical e.g. resonance?

    Edit: I've just seen the video. I can't hear the noises but one other thing occurs to me. If the thermal paste hasn't been applied correctly the CPU could throttle. What sort of temperatures are you getting under load? If you use RealTemp it will indicate whether throttling is occurring in 'Thermal Status'.

    Realbench and some other benchmarks can give some odd results on a 6core. I've noticed that with mine, in some tests the load per core is so low it doesn't even come out of idle clock speed and runs the whole test happily at 1.5gHz. Go in uefi and disable speedstep C states so it can't underclock itself on the fly, it will give you better result.

    As far as noise... I would suspect it's the HDD first creating vibrations. WD blacks spin hard and can make a racket. Disconnect power to them and see if the noise goes away. If not I would disconnect all but the cpu fan so it's as quiet as possible and easier to pinpoint which component if it is coil whine.

    I think my GPU is throttling. Interesting progress. When I run furmark to test my GPU, my GPU load is 0%-4% for ages, leaving me with a black screen and then a stuttery image, eventually the GPU load kicks in and furmark runs smoothly.

    Also, Premiere Pro now says that Mercury Playback Engine GPU Acceleration (CUDA) is NO LONGER supported. When previously it was recognising my graphics card.
