    First thanks to svl7 bios for unlocking its potential and remove throttling- sincere thanks to u :thumbsup: and thanks to MickyD1234 for helping me out when i was unable to post any replies to any forum cause of my college wifi fortinet web filter :)

    At first even after flashing svl7 bios i wasnt able to overvolt...it simply crashed...then i figured out and i did FN+F5 which switches the graphics from primary Intel to now primary nvidia graphics

    My 3dmark11 score at stock-P4306 with graphics score 4063 and physics score 8205
    NVIDIA GeForce GTX 765M video card benchmark result - Intel Core i7-4700MQ,Alienware unknown

    never was an major improvement over my old M17XR4 gtx 675m which scored graphics 3dmark11 at 3800 overclocked [a 100 watt gpu!!]

    My 3dmark11 score at CORE +378, MEMORY +896, VOLTAGE +337.5MV, POWER TARGET 150%---> USING NVIDIA INSPECTOR
    P5942 with graphics score 5787 and physics score 8150

    Now this score is matching stock gtx 680m performance !!

    My 3dmark firestrike at stock
    Graphics Score 2718 and Physics Score 9523

    My 3dmark firestrike at CORE +378, MEMORY +896, VOLTAGE +337.5MV, POWER TARGET 150%---> USING NVIDIA INSPECTOR
    Graphics Score 3990 and Physics Score 9459

    Now this score is more than stock gtx 770m and again equivalent to gtx 680m at stock and gtx 860m at stock[gtx 860m at stock only scores 5000 in 3dmark11 though strange]

    Now that is atleast a 45% improvement in performance compared to stock gtx 765m...it sure overclock likes a beast !!

    All this and temperature max is 76 c

    Questions:
    The voltage meter is maxed out in nvidia inspector any ways u know guys to increase voltage for further overclock ??

    Also i see the hwinfo is not working with alienware 17, the best i could see is 3400 rpm !! shocking my old M17XR4 can go 7000 rpm with hwinfo, so any ways u know guys to increase the fan speed ??

    Give ur opinions guys :)

    It is a BIOS limitation. Dell would have to push a modded BIOS out to fix that and they probably won't, there have been complaints about the fans for a long time and they don't seem to care.

    Nice results! I don't know the stock voltage of the 765m. What's your current voltage under load?

    Happy for you, but that's much lower than stock 680M performance.

    AND WHAT'S WITH THE FONT SIZE.

    Clearly comparing with NVIDIA GeForce GTX 680M - NotebookCheck.net Tech
    i have almost reached the same level with this overclock

    1. Synthetic benchmarks do not directly translate to real-world performance.
    2. Those are very old numbers. Driver and 3DMark updates have increased scores dramatically. Just ask any 680M owner to run a stock test for you right now on latest drivers, you will see what I mean.

    And my eyes thank you for making the font size normal.

    You'd be surprised. Here is my score going up by over 1000 points in one year.

    NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3630QM Processor,LENOVO INVALID

    NVIDIA GeForce GT 650M video card benchmark result - Intel Core i7-3630QM Processor,LENOVO INVALID

    The only differences are +30 MHz on the GPU core plus the aforementioned VGA driver and 3DMark updates.

    And even those are old results. I haven't run 3DMark 11 in a long time. I bet if I do it now on latest driver and versions of 3DMark and SystemInfo, I'd get higher scores still.
