    I'm trying to overclock my computer and ı have couple of questions in my mind.


    System Specs:

    Cpu : İntel Core-i7 2600k (@4430Mhz 1.368V 9:9:9:24) (%100 Fan speed)
    Ram : Kingston 8GB(2x4) 1600 Mhz 1.65V
    Gpu : 2x Asus HD 6970 Direct Cu II 2Gb (@ Core:960Mhz Memory:1425Mhz Stock Voltage) (%100 Fan speed)
    Mainboard: Asus p8z68-V
    Powersupply: Highpower Absolute 1000W
    Soundcard: Creative X-Fi Titanium
    MOnitor: (1920x 1080) @60hz Led Tv
    Chasis: Aerocool XPredator(With full of fans)
    Storage: 2TB Western Digital Caviar Black 7200 Rpm 64mb Cache Sata-III (With 60Gb SSD as cache, İntel smart respnse technology)

    All of the drivers are up-to-date and bios is up-to-date.

    My first question is, as you see i overclocked gpus to 960mhz Core clock and 1425mhz memory clock at stock voltage. My 3DMark 11 score slightly increases but i don't gain any important performance in game benchmarks.
    Should i use these gpus with these clock speeds for daily use? Will these clock speeds cause damage ? (All temps are good and ı dont change voltages). İf there is any possibility to couse damage to gpus , i will revert
    back to default clocks because the performance difference is very small.



    I have done a lot of benchmark test and i'm posting the results, is there any problem in these results ?

    My second question is, as you can see in my system specs i overclocked the cpu to 4400 mhz @1.368V . I can't increase core speed to above 4400mhz(X43.0 multiplier). If i increase it i'm facing with blue screen of death in prime95 test.
    i'm posting Bios Settings, what settings should i change in bios to reach above 4400mhz ? ( I read a lot of guides on the internet but non of them helped me)

    My last question is, when i start my computer sometimes it makes double boot . (All fans starting to spin and at that time nothing on the screen , after few seconds it completely turns off and start again without any problem.) But its annoying.
    Bios is up-to-date. What can i do about this problem?



    Thank you.
