Primer Guerrilla Overclocking Why overclock? How do you want a PC of 30% or more fast, free, and with very little risk? It’sa bit of a no-brainer really is not? We all know that at some point in the future, we will upgrade our PCs, which is usually to solve a performance problem. It is too slow, it stutters and freezes or simply to slow its unusable with new versions of Windows, games or software applications. Overclocking is more popular than ever as a way to get the most out of your PC without having to spend money. With an economic situation where they are which is very compelling. We are unique among PC makers just a few pre-overclocked and optimized PC on the cutting edge of performance curve with our technology Cryo Boost ™. What “Guerrilla Overclocking? Guerrilla Overclocking is a method we have developed ourselves that balances time required to reach a given overclock compared to the benefits. An Internet search or browse forums overclocking reveal pages and pages of material that overclocking is extremely time consuming, full of errors and omissions and assumes much prior knowledge and experience. Our comprehensive process and the method we use to produce our client PC includes: · Hardware design, · overclocking techniques and procedures, · Monitoring and Warning, stress · Database registration and publication, · Operating System Configuration · and, finally, and soak tests. We will not get into the whole method of this practice on the practical primer we are just going to cover enough for you quick results so you can go solo with your own overclocking when you’ve reached the end of the few pages of this article. You could consider it a method for the moment not only poor overclocker it will not take long to learn it also takes only minutes to implement. Although we do not misunderstand the overclocking is very complex and it is as much art as science and the complexity and challenge of extreme overclocking should not be underestimated. What we try to give you a significant boost in performance through a few simple steps and without any complexity. Is not it risky? We’ve been overclocking the memory, graphics processors and motherboards for over ten years and we have not had a single production failure which took place after the overclocking. We have had many failures in the laboratory but that’s what the research laboratory for! We tested several configuration options and test beds many studies have Summer safety limits are, and it is really quite a long way to go before achieving anything like a breaking point in overclocking the hardware. There are lots of free space built at the end quality of technology to cope with widely varying circumstances in which it may terminate the working groups. For example, it is quite typical for a current Intel Core 2 Quad with a 2. 66GHz plant adjust the clock speed to run over. 3 5 GHz without adverse consequences. Overclocker Mission Control There are all sorts of tools that are different suppliers for you overclock, you should leave them on DVD do not bother installing them. They tend to change the dynamic performance based on assumptions, data monitoring and use and can lead to stability problems of confusion or artificial ceilings performance. They also tendency to “smooth overclocking of your PC if the tool is running in your instance of Windows, then there is no overclocking in force at all. The only tool you really need your BIOS and your BIOS allows you to better understand what is happening. The great thing about the BIOS is really, really simple and does what you ask. It is not big enough for many Intelligence is really just a bunch of data that tells your PC how to run in a way that will work as you expect it. There are many complex settings in your BIOS and some are even important, Many simply are not. We will present only a few keys you need to know and make a difference. Clocks The clock speed is generally more for performance than the CPU has more cycles per second to the same task, if it does so more quickly. The clocks also refer to the memory and bus interface and processor speeds. We will try to speed the highest possible common clock. Normally, you find these settings on the advances sometimes called Advanced, Tweaker, or overclocking settings Guru. The table below shows a typical high for 1333 and 1600 motherboard and CPU FSB (or typical upper and lower) . 1333or FSB setting BIOS FSB 1600 expected minimum Upper Limits Using external clock (or reference clock) 400FSB (or Core i7 QPI / AMD HyperTransport) multiplier 1600MHzCPU (usually locked): 10CPU Clock: Clock 4GHzMemory (DDR2) : 1066MHzMemory Clock (DDR3): You may have noticed the 1600MHz FSB is 4x the external clock, and processor speed is x = External clock multiplier (ie Clock = 2. 66GHz = 8 x 333 and 1333 MHz FSB = 4 x = 333). Note also all but Intel Extreme Edition processor AMD Black multiplier can not be changed and is “locked.” Simple is not it! Now if you have a good quality brand or PC motherboard with an Intel or nVidia chipset product over the last three years, your PC will be capable of speeds over and over. nForce 780i chipset with an Intel or P35/X38 or later you can easily exceed a speed of 1600 MHz FSB. In our experience, refine the memory speed is much less important to the overall performance and if you’re really poor time just leave it to the default configuration. The only thing to watch is the default if you just increase your speed you increase the FSB speed of the memory because they are linked and it is very likely that your memory stop working well before reaching the limits of the FSB or processor. Remember to manually “lock” the memory speeds to default production speed and latency, typically at 800 MHz or 1066 MHz for the former Auto for the latter. Each time you increase your FSB you might need to check again that you do not inadvertently increase the speed of memory. The Volt If the power of your PC (volts and amps) had no effect on the rate of clock we not care about power, but it does. As human beings, the more work your processor has more food (in volts and amps) needed to maintain it. We must therefore carefully feed more volts, making it draws more amps (Remember Ohm law; more == more volts amps!). Here lies the crux of overclocking and what differentiates a good speed of a poor slow. If we increase the tension and thus increase the power dissipation (in amperes) the resistance of all circuits involved some of that energy has increased in the heat. Increases in heat from conductor resistance and we are entering a vicious cycle which potentially creates more heat resistance that creates more heat, etc. This cycle is known as thermal and / or runaway current. It is conceivable that adding more tension increases resistance and effectively reduces overclocking height and we have observed this phenomenon empirically. So do not unnecessarily increase your stress that we want them to be as low as we can go out with. The types of increases that we’ll do in this exercise are the order millivolts.’s son inside the integrated circuits are finer than human hair, a beautiful lot, so we have to make changes or small they burn, or resistance Sky High and they will stop functioning. This piece of copper on top of your CPU (known as the IHS Integrated Heat Spreader or) can heat up to 70 ° C and beyond. Now imagine how hot the inside of your CPU are thinner than a human hair need to be able to raise the temperature of several grams of copper that much! Now we are afraid of death will increase the tension stop s to worry about it because the table below lists the limits of maximum operating voltage that keep you well within a large safe. BIOS Setting CPU volts (VCore): 1. 2V to 1. 4VMemory volts (vDIMM) DDR2: 1. 8V 2. 0VMemory volts (vDIMM) DDR3: 1. 5V to 1. 66VMCH volt Core: 1. 2V to 1. 4VCPU VTT (FSB Termination) V: 1. 2V to 1. 4VNorthbridge: 1. 25V 1. 45V Other Settings There are a few other settings below that you can possibly change, but they should not be necessary to refine a overclock near the limits of stability and functionality. C1E CPU BIOS Setting: Consumer-Enabled reduces the CPU power and heat with a capacity idle state CPU TM: Enabled-heat protection, throttle the CPU from overheating, may mislead you by testing your CPU overclocking Execute Disable Bit: protection against viruses Enabled by AIDS-protection code execution in memory pages substantial CPU virtualization: Virtualization-Enabled Layer support HyperThreading CPU: Enabled-CPU Usage Increases effectively a virtual second core heart, supporting an additional thread performance CPU Intel Speed Step (EIST) does Enabled gas CPU voltage and speed to use, could confound the results overclock PCIe Clock: 100 – Can usually be increased by at least 5 % and increase the speed of PCI Spread Spectrum Spread Spectrum-Enabled Disable generally improves stability SATA Configuration: Enhanced-Usually, the default IDE or Enhanced IDE mode which is slow. Change the mode to AHCI or RAID supporting NCQ and up to 300MB / s transfer speed. You will need to have the appropriate drivers installed in Windows first (or already installed.) Vista supports AHCI usually default. Improve PC performance in six Steps Ok now you know all about the basics of overclocking and bounds about where you work, we can now give you one minute and our simple process Six steps to increase the performance of your PC: 1. Put yourself in your BIOS and go directly to the page settings for bus speeds and parameters of the processor 2. Set your BIOS settings and bus speed processor manual, which will open a range of parameters described above, and we will solve in the next three steps. Set your CPU VCore voltage to 1. 4V 4. Set your CPU VTT (FSB Termination) 1. 3V 5. Make sure that the speed of your RAM is set manually in its limits (usually between 800 and 1066 MHz DDR2 or DDR3 1333MHz) 6. The next step depends on the type of processor you have: a. CPU FSB 1333 (multiplier locked): i. Set your external clock up to 400MHz, or FSB your 1600MHz, if available in your BIOS ii. Giving you a new processor speed up to 3. 6GHz b. 1600FSB CPU (Extreme multiplier unlocked): i. Let your external clock at 400 MHz ii. Increase your multiplier to 9, giving you a new processor speed of 3. 6GHz 7. Save the BIOS settings and restart your PC and enjoy up to 30% performance boost + This works exactly as described with 95% of the systems we encounter. If this does not leave you just as described and tension reduction of the external clock, multiplier or FSB speeds back to default and increase gradually one step at a time until you reach a point where your system becomes unstable, then back down. This is more reminiscent of the typical process of overclocking is described elsewhere. It is an iterative process which stops when you are on the brink of stability and go beyond, but this approach takes significantly longer. Arghhhh, My PC froze Is it broken?! If you have stuck to this direction primer and tensions over your PC will not broken. In fact, changing clock speeds alone is very unlikely to do any damage. We have never seen a case where it caused damage, even in laboratories in terms of destructive testing . Heat kills, voltage and current increases which increased the heat! Be very careful when increasing your blood and you’re not known for overclocking does not go beyond what we recommend here above. Now, my PC does not start If you make changes to the BIOS and boot the PC normally, all is not lost. Most modern motherboards have what is commonly called “Crash Free BIOS or something similar. In these cases, a hard power off or just a soft reboot you will display your BIOS settings to factory default BIOS temporarily loaded so you can change the settings of your overclock. Just reduce your overclock as described above or start from the beginning the default settings and gradually change things restart each time until you find what is causing the instability. If you do not have an accident without BIOS or does not work then you need to clear the CMOS BIOS. Refer your motherboard manual for instructions on how to do (it is usually of a single button or a knight). Or simply remove the CMOS battery on the motherboard, which will achieve the same thing. Assumptions we make a number of assumptions about the hardware configuration of your PC you can enjoy this primer. • You have a good intermediate level of understanding of PC hardware, software and operating systems • You are getting comfortable in the PC BIOS and changing settings • You are at ease by changing the configuration of your operating system • We do not cover overclocking your graphics card, but we recommend you do this as it could be the component that you held back, same goes for the memory of your computer Your full has adequate cooling and good quality components installed Conclusion When you consider that a new PC three years ago is now about 20-30% slower than the PC later Today, you can see it now in a PC three years gives you a PC to the current level of performance without additional costs. This is not a trivial exercise and it’s not for the timid or inexperienced but once you’ve captured the essence it is surprisingly simple to do and you get very useful results. Alternatively you can buy your next PC from someone like us, and we do all this and more for you and guarantee, above. Plus, you get a PC that is two to three years ahead of the competition from the point of purchase. Regarding the industry giving you almost 100% more for back your return on investment for most of halving the price of PCs.
