[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 No.2 ASUSP 7P55D Deluxe Main Board. Oh ~ What shining words they are! No.3 Kingston DDR3-2000 2GB No 4. It only took me 29 USD. Mamania! No.5 675W Power No.6 Case: The full tower black case OK! Everything is ready to fight! It cost me more than one month salary…XD 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. by Tom’s Hardware From Intel official 【How to enable Turbo Boost】 The point is how to enable Intel Turbo Boost. Please enter your BIOS. 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. 【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. It will show the Intel CPU logo, and if it is similar to my gadget, that means Turbo Boost is successful. 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 Case A-(2): Stock freq without Turbo. Nuclearus Multi Core: ALU: 5445 / FPU: 7967 Case A-(3): Stock freq without Turbo. Cinebench: 3178 Case A-(4): Stock freq without Turbo. 7-Z Benchmark: 2982 Case B-(1): Stock freq with Turbo. Hyper PI (8M): 2m24s Case B-(2): Stock freq with Turbo. Nuclearus Multi Core: ALU: 6632 / FPU: 9769 Case B-(3): Stock freq with Turbo. Cinebench: 3657 Case B-(4): Stock freq with Turbo. 7-Z Benchmark: 3521 Case C-(1): OC with Turbo. Hyper PI (8M): 1m58s Case C-(2): OC with Turbo. Nuclearus Multi Core: ALU: 8353 / FPU: 12330 Case C-(3): OC with Turbo. Cinebench: 4631 Case C-(4): OC with Turbo. 7-Z Benchmark: 4332 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. 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? 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 (b) Running Hyper PI 8M/1core power consumption: 185.8W, best time 1m58s. 2. Traditionally OC to 4.13GHz without energy saving setting and Turbo Boost. (a) Idle power consumption: 178W (b) Running Hyper PI 8M/1core power consumption: 217.4W, best time 2m4s. Conclusion: It obviously reveal energy saving when Turbo boost is on, and now I can eat more turkeys in Charismas. 【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.
