Bagaimana sih cara overclok laptop? Sebenarnya ada 3 cara untuk melakukan overclock processor laptop Intel maupun AMD. Yang pertama adalah dengan cara mengubah pengaturan pada settingan BIOS menggunakan software generik untuk mengubah voltase CPU dan juga timing-nya, dan ketiga, dengan menggunakan software yang dirilis Intel atau AMD sendiri untuk melakukan overclock processor laptop. Jawabnya: Lakukan Overclocking Melalui Intel XTU! Seperti bisa disaksikan diatas, software utility ini mampu mengubah CPU Multiplier, BCLK, Voltase, hingga ke Power Limit dari CPU anda. Setelah berkutat dengan benchmark Intel XTU selama dua bulan, beberapa waktu lalu 41 overclocker dari berbagai negara di dunia yang mengikuti.
Contents.Overclocking CPU on UbuntuOverclocking is not a recommended approach to improve the performance of the Ubuntu system if it is used in daily operations, as this would affect the stability of the system. However, since gaming in Linux becomes possible as more and more video games distributors release video games in Linux, one may wish to get better performance from the overclocked CPU, accepting the trade off of the potential loss in stability. This page describes how to overclock the Ubuntu system.Please be warned that overclocking may introduce permanent damages to your system, particularly by increasing the voltages. Do so at your own risk!HardwareThe CPU can be overclocked in the configuration of the BIOS. You need all of the below if you wish to overclock the CPU:. An overclockable CPU. An overclockable motherboard.
An up-to-date motherboard BIOS which recognizes the CPUWhen all is ready, go to the BIOS configuration page by press (or some other key, which will be displayed to you at boot) when the system boot up. Find and change the CPU overclocking settings, which should be named as 'CPU frequency', 'CPU multiplier', or similar.
Save the changes and reboot the system.If you are lucky, the system should boot up as normal. If the system has no response, you may need to reset the BIOS (By rebooting a few times, shorting the reset pin, Googling, etc.) and test other overclocking settings.VerifyingIntelMost Linux tools do not show the correct overclocked frequency. Fortunately, Intel released an official tool, turbostat, for this purpose. Below are the installation steps:1. Check the current kernel version, and install the required package. # uname -rX.XX.XX-XX-generic# apt-get install linux-tools-X.XX.XX-XX linux-cloud-tools-X.XX.XX-XX2. Install the MSR module.
# modprobe msr3. Open a terminal; run a CPU intensive application, here the OpenSSL speed test.
# openssl speed4. Open another terminal; run turbostat to show the actual frequency # turbostatcor CPU%c0 GHz TSC SMI%c1%c3%c6%c7 CTMP PTMP%pc2%pc3%pc6%pc7 PkgW CorW GFXW100.00 4.39 3.19 0 0.00 0.00 0.00 0.00 83 83 0.00 0.00 0.00 0.00 53.31 44.71 0.000 0 100.00 4.39 3.19 0 0.00 0.00 0.00 0.00 83 83 0.00 0.00 0.00 0.00 53.31 44.71 0.001 1 100.00 4.39 3.19 0 0.00 0.00 0.00 0.00 75Column 'GHz' is the actual frequency the CPU running at. Column 'TSC' is 'timestamp counter' the CPU reported normally running at.
As above shown, the CPU is reported normally running at 3.19GHz while is being overclocked at 4.39GHz.Column 'CTMP' is the core temperature of the CPU core. The core temperature can be used to estimate the Tcase temperature to see if the CPU is overheating or not. Below is a rough formula for temperature estimation:CTMP = Tcase + 15CThe Tcase temperature of Intel CPU can be checked at. In this example, Maximum Tcase of the CPU is 72째C, as a result Maximum CTMP is projected be roughly 87째C. The reported reading 83째C is below the threshold.If the CTMP is too high, you may wish to lower the overclocking frequency or acquire a better CPU cooling fan to avoid overheating.AMDTODO.
With the introduction of its first 45nm PC processors back in 2007, Intel really raised the bar for overclocking headroom.Such is the consistency with which the last of the Core 2 chips achieved monster operating frequencies, it's got to the point where an overclock of a gigahertz or more on standard voltages seems like a God-given right to many enthusiasts.The latest D0 stepping of the Bloomfield Core i7 chip is an extremely nifty overclocker, too. With that in mind, we were extremely anxious to discover whether the microarchitectural changes made with the new Lynnfield Core i5 and Core i7 CPUs would allow the good times to keep on rolling along.Would the added on-die features such as the PCI Express controller put a drag on clock frequencies? Or is Lynnfield another flier from Intel?The short answer is that our fears of an incoming nerf were entirely unfounded. Lynnfield clocks up at least as well, if not better, than existing Intel processors.Intel's now traditional 1GHz+ boost still applies. As for AMD's Phenom processors, unless you have an exotic cooling kit to hand, the meagre headroom they deliver looks pathetic in comparison.Our Phenom II X4 965 Black Edition chip won't clock up by more than 400MHz without massaging the voltage settings.
But what about specifics?The Core i5 750 is officially a 2.66GHz model. Honeywell galaxy software services inc. Our sample chip hits 4.2GHz, using nothing more than a standard air cooler and stock voltages. That's idiot-proof, risk-free overclocking headroom of 1.5GHz.More to the point, it's the difference between 100 per cent smooth frame rates or occasional stutters in demanding games, such as World in Conflict.As for the 2.93GHz Core i7 870, well, it produces a little less impressive results. A maximum frequency on air of 4.33GHz is pretty awesome in isolation, But it's only marginally better than the Core i5 750 manages.That's a pretty poor result given that the Core i7 870 costs nearly three times as much as the 750. As ever, it's a case of diminishing returns as you scale heights of Intel's processor price list.Setting your BIOSFirst a disclaimer. Despite the fact that overclocking has become utterly mainstream in recent years, some risks remain. We therefore suggest you follow a few golden rules.First, never make a change to your system's BIOS settings that you do not fully understand.Second, take small steps, not huge leaps.
Intel Processor Overclock
It'll take a little longer, but you'll get better results and remove virtually all the danger from the process.Third, if you want to guarantee that you don't toast your CPU or mobo, steer clear of voltage tweekery.With that behind us, here's our guide to clocking the twangers out of Intel's new Lynnfield processor.1. We'll focus on the Core i5 750 chip as it delivers the best overclocking bang for your buck. Hop into the BIOS, typically by hitting Del or F2 when the boot splash screen appears.2.
All Lynnfield Core i5 and Core i7 chips have locked CPU multipliers. So as with the non-Extreme Edition versions of the Bloomfield Core i7 chip, the key setting is the base clock. As standard, it runs at 133MHz.3. Your BIOS should also divulge your chip's multiplier setting. If it's not displayed, some simple maths using the operating frequency and the baseclock will give you the multiplier setting.

In the case of the Core i5 750, that's 2.66GHz and 133MHz respectively, which translates into a multiplier setting of 20. Therefore, having set the global overclocking option to manual, you can begin to increase the base clock.4. We'd advise base clock steps of 10MHz at a time which gives you a 200MHz boost in terms of overall operating frequency. Once the new setting has been applied, reboot your PC all the way to the desktop and test for stability. Multi-threaded benchmarks such as Cinebench are handy tools here.As you increase the frequencies, bear in mind that the speed of your system memory is also linked to the base clock. Big overclocks require that you adjust the memory dividers in the BIOS to keep your RAM frequencies under control. Exactly how high your memory can run depends upon both your DIMMs and your motherboard.5.
With the right kit, memory speeds beyond 2GHz are possible. However, remember that Core i5 is not particularly sensitive to memory bandwidth, so chasing high frequencies at the expense of stability isn't worth it.The final part of the Core i5 overclocking equation is Turbo Boost, Intel's auto-overclocking feature. In our experience it actually allows you to achieve higher ultimate frequencies.Our Core i5 chip refuses to boot above 4.05GHz in terms of non-Turbo frequency. But once into Windows, it happily runs at 4.2GHz when Turbo Boost kicks in.
