    [OC]Intel i7 860 No brain OC, easily up to 4.39GHz

    The history as bellow...
    Last Month, my old computer P4 stopped working. I couldn’t find any problem makes my computer down.
    After two days…I bought these.

    CPU: Intel(R) Core i7 860
    M/B: ASUS P7P55D Deluxe
    Ram: Kingston 2G DDR3-2000
    HD: Segate 500G
    VGA: NVIDIA GTX 295(To play BIO5, I borrowed from my gf )
    POWER: 675W (support by my gf)
    Cooler: Thermaltake Contact 29
    Testing Vehicle: WT210 Digital Power Meter (Borrowed)

    No.1 Intel Core i7 860 CPU
    [​IMG]

    No.2 ASUSP 7P55D Deluxe Main Board.
    [​IMG]

    Oh ~ What shining words they are!
    [​IMG]

    No.3 Kingston DDR3-2000 2GB
    [​IMG]

    No 4. It only took me 29 USD. Mamania!
    [​IMG]

    No.5 675W Power
    [​IMG]


    No.6 Case: The full tower black case
    [​IMG]

    OK! Everything is ready to fight!
    [​IMG]

    It cost me more than one month salary…XD
    [​IMG]

    Somebody told me Intel core i7 processor doesn’t need to tune number to OC.
    It’s called Turbo Boost. Then I found some information on website. Let’s see what’s TB?

    【About the Intel Turbo Boost】

    We can get higher frequency when Turbo Boost is enabled.
    The frequency level is determined by core status. For example, my i7 860:

    [1 Core Active] : 2800 + 133*5 = 3465 (3.46GHz)
    [2 Core Active] : 2800 + 133*4 = 3332 (3.33GHz)
    [3 or 4 Core Active] : 2800 + 133*1 = 2933 (2.93GHz)


    This is so called Bin Upside. In a word, fewer cores activate, higher frequency they generate.
    I think TB(Turbo Boost) is helpful for me , because I usually do some programs like movie converting,
    files compress’ etc…only need single core active then I can get higher frequency.

    【How to enable Turbo Boost】

    The point is how to enable Intel Turbo Boost. Please enter your BIOS.
    [​IMG]

    Due to one MB I own, I can only explain you P7P55D Deluxe.
    In default, Turbo Boost is enable, but if you want make sure it, please enable the following four options.

    (1) Ai Overclock Tuner: [Manual] or [Auto]
    (2) CPU Ratio Setting: [Auto]
    (3) Intel(R) Speed Step(TM)Tech: [Enabled]
    (4) Intel(R) TurboMode Tech: [Enabled]

    PS: If you disable “Intel(R) SpeedStep(TM) Tech”, TurboMode Tech will not be display in BIOS.
    [​IMG]

    【Turbo Boost monitor】

    In windows, you can turn on Intel Turbo Boost Monitor Gadget which provides you to monitor turbo boost.
    You can download here.
    http://downloadcenter.intel.com/dow...ng/TurboBoostSetup.exe&DwnldId=18353&lang=eng
    (support win7and vista)

    After finish installing the gadget, right click your mouse and click “Gadget” to show the icon.
    [​IMG]

    It will show the Intel CPU logo, and if it is similar to my gadget, that means Turbo Boost is successful.
    [​IMG]

    If not, it will show a big cross in the gadget like this.

    【OC without brain! XD】

    Honestly, my experience of OC is very poor,
    and I get lazy for setting too many things to earn little efficiency of CPU without guarantee.
    By Turbo boost, I can OC without brain, and for an amateur like me,
    I roughly test Turbo boost with following programs.

    (1) Hyper PI 0.99b (1Core, 8M, Realtime)
    (2) Cinebench R10 (1Core)
    (3) Nuclearus Multi Core 2.0
    (4) 7-zip (Benchmark Test,16M, 1core)

    For case A:
    Stock and Turbo Boost 【Disabled】
    Case B:
    Stock and Turbo Boost 【Enabled】
    Case C:
    OC and Turbo Boost【Enabled】


    Case A-(1): Stock freq without Turbo. Hyper PI (8M): 2m49s
    [​IMG]

    Case A-(2): Stock freq without Turbo. Nuclearus Multi Core: ALU: 5445 / FPU: 7967
    [​IMG]

    Case A-(3): Stock freq without Turbo. Cinebench: 3178
    [​IMG]

    Case A-(4): Stock freq without Turbo. 7-Z Benchmark: 2982
    [​IMG]

    Case B-(1): Stock freq with Turbo. Hyper PI (8M): 2m24s
    [​IMG]

    Case B-(2): Stock freq with Turbo. Nuclearus Multi Core: ALU: 6632 / FPU: 9769
    [​IMG]

    Case B-(3): Stock freq with Turbo. Cinebench: 3657
    [​IMG]

    Case B-(4): Stock freq with Turbo. 7-Z Benchmark: 3521
    [​IMG]

    Case C-(1): OC with Turbo. Hyper PI (8M): 1m58s
    [​IMG]

    Case C-(2): OC with Turbo. Nuclearus Multi Core: ALU: 8353 / FPU: 12330
    [​IMG]

    Case C-(3): OC with Turbo. Cinebench: 4631
    [​IMG]

    Case C-(4): OC with Turbo. 7-Z Benchmark: 4332
    [​IMG]

    The reason why I test is I want to know Turbo boost is only for numbers or really functional and the answer is really functional!
    After Turbo boost, CPU gets high freq to work better than disable.
    [​IMG]

    i7 860 stock freq is 2.8GHz.
    With Turbo Boost is auto OC to 3.48G easily.(only not to turn off Turbo…)
    Case C, OC to 4.39GHz with Turbo, is to tune BLCK and CPU voltage for good.
    You may follow my setting in BIOS.

    【Addition ~ To buy more money】

    If you want to buy more turkeys, you have to save more money, saving energy.
    I think Turbo boost is very humanity that only when CPU is loading then turbo stars.
    It saves energy much more than traditional OC that idle maintains same freq.
    How to turn on energy saving on this MB?
    [​IMG]

    C1E Support and Intel(R) C-State Tech are [Enabled], and C State package limit setting is [ Auto].
    If your MB is EISTE, not C-STATE, please set [Enable].

    To prove turbo can save money, I borrow a power meter to make a simple old school test.

    1.OC to 4.39GHz with energy saving setting and Turbo Boost.
    (a)Idle power consumption: 129.8W
    [​IMG]

    (b) Running Hyper PI 8M/1core power consumption: 185.8W, best time 1m58s.
    [​IMG]

    2. Traditionally OC to 4.13GHz without energy saving setting and Turbo Boost.
    (a) Idle power consumption: 178W
    [​IMG]

    (b) Running Hyper PI 8M/1core power consumption: 217.4W, best time 2m4s.
    [​IMG]

    Conclusion:
    [​IMG]

    It obviously reveal energy saving when Turbo boost is on, and now I can eat more turkeys in Charismas.
    [​IMG]


    【Final thoughts】:
    (1) Intel Turbo Boost is real and very easy to be.
    (2) Strongly suggest to enable Turbo Boost and energy saving setting to save your butte.

    This article was completed by me and my friend.
    We just want to share how easily OC above 4G by using TB.:)

    Spent a while OC'ing mine this morning, hit 4GHZ Stable (200x20), but stressing it became too hot, was hitting high 90's using the Noctua NH-U12P SE2 cooler, all in all a bit disappointed with its performance, but ohwell.

    Good article. :)

    The ratio of performance / cost is not bad...
    HDT seems good..
    But assembly is a little bit hard when you install it onto M/B.

    If you want to get higher performance, you can install second fan on contact 29.

    Noctua NH-U12P SE2 is a good cooler.

    Do you hang on two fans on it ?

    I agree completely, the thing's bloody MASSIVE, and yes, 2 fans.

    I'm keeping a current clock of 3611MHz (Says Coretemp), and haven't hit 55 after an hour of playing GRID.

    Here's a Stock (2.8GHz) vs 4GHZ comparison, on my system atleast (Rig in sig)

    [​IMG]

    The 3D Mark scores are based off the CPU tests only.

    After using OCCT (Linpack) for about 20 minutes on 200x20, i saw temp hit low 90's.

    Also got the results for 3.2GHz and 3.6GHZ if you want to see them too.

    It's so cool by your test.:thumbup:

    Have you ever been use prime 95 to test your PC @ 4G?

    I am interesting in this, and wanna know the temperature.:lol:

    Well, as I said, I ran OCCT Linpack, and it hit temps of low 90. Linpack's better then Prime95 imho.

    the about of heat coming from my case was insane.

    Now try disabling turbo and EIST etc, and running all 4 cores (8 using hyperthreading) at 4.39GHz @1.448V:tongue:
    Marvel at how hot that baby is at idle, and then run Prime95.:shock:
    **But for Gossake be quick to hit the Stop button before that core heats up and shuts down**
    :lol::lol:

    Vista and Windows 7 use all 4 cores quite a bit. I think the best overall option is to run the CPU at 3.6GHz @ 200MHzx18 at around 1.2V, and disable Turbo,EIST etc. Latencies and Inter-Core performance is better, and you wont get crashes during heavy gaming etc. Your Core will be 3.6GHz, Your QPI Link is 3.6GHz, your Memory Throughput is around 25GB/s (if you have DDR3-2000 RAM) and you can run your PCI-E bus 15% higher if your a gamer and the thing will not overheat with decent air cooling. If you have a decent water-cooling setup then stuff it all, just Turn the Turbo off and run it at 4.25GHz and above:lol:

    Don't get me wrong though, turbo mode on 45 Billion computers will dramatically drop carbon emissions and that ain't a bad thing:)

    Nice review by the way.....................

    I found that your grammatical and punctuation errors greatly emphasised how much of a "no brainer" this was. Nice read :tongue:

    Haha...

    I can fully accept your thought.
    In some games, 4core plus HT will perform the higher performance.

    Tks for replying!:thumbup:
