I have here the ways on how to overclock your computer, just follow every step because this are a very crucial ways and you must really focus very carefully for each instruction. After all, what you will do is to make your PC a powerful one.Overclocking your PC is like getting a free upgrade. By adjusting the speed at which your desktop system’s core components–processor, memory, and motherboard–operate, you can score a noticeable performance gain.
It’s not for the faint of heart (or hardware), however. You can cause your system to become unstable and, in a worst-case scenario, damage components and void your warranty. But if you’re ready for the challenge, read on. This crash course will take you through the basics–and, with luck, help you keep the crashes at bay.
INSTRUCTION:
Step 1: Get the right hardware~
Overclocking can save you cash by letting you buy lower-end equipment when building or upgrading a PC, or help you squeak a little more performance out of an older system. If you’re buying parts with overclocking in mind, research them first in online forums because some processors, motherboards and memory have better reputations for overclockability than others.
Three key components determine your PC’s overclocking potential. First, you need a motherboard with a BIOS that lets you adjust your processor’s speed. Most motherboards you can buy for building your own PC allow this. (These same boards also tend to be used by smaller PC makers in their systems.) Until recently, few motherboards from major PC makers such as Dell and Hewlett-Packard gave access to overclocking settings, though the capability is present in their newer enthusiast systems.
Next is the processor. The fastest ones have little headroom for overclocking–typically, they’re already running at close to their peak speed. Conversely, midrange processors often cost less than half what the current top-end CPU does, but they are often overclockable into the same speed range as a high-end CPU.
Finally, you can overclock memory, though only the newest DDR2 and DDR3 modules can be pushed hard enough to deliver a significant performance boost. Your graphics card (if your PC has one) is a potential fourth overclocking candidate, but the procedure varies by the model you have.
Step 2: Beat the heat~
Running your processor and other components at higher-than-rated speeds increases the heat inside your system, so to keep things running reliably, you may need to boost your PC’s cooling. The main target here is the heat-sink/fan combination that cools your processor. Using standard coolers, some processors, such as Intel’s quad-core Core 2 chips, already run uncomfortably hot at stock speeds when working at full capacity. If you encounter heat troubles (operating temperatures vary by processor, but should be between 30 and 65 degrees Celsius), a CPU-cooler upgrade is order.
A cooler like Thermalright’s Ultra-120 eXtreme can significantly boost your overclocking potential. With this heatsink and a 1,600rpm 120mm fan, our maximum temperatures with a Core 2 Extreme QX6700 processor dropped from 85 degrees Celsius to a more manageable 63. Heat pipe-equipped heatsinks such as the eXtreme have gotten good enough that water cooling is needed only for extreme overclocking. Just be warned: Some upgrade CPU coolers require you to remove the motherboard to install them–the cooler may use a nonstandard backing plate (the heatsink screws into this) that needs to be situated underneath the motherboard.
Step 3: Overclock your processor~
Before you start overclocking, you need to understand how your processor’s speed is determined. While newer processors typically have an internal speed (the rate at which they execute instructions) anywhere from 1.6GHz to 3GHz, they communicate with the motherboard and memory much more slowly. The communication channel used for this is called the front-side bus (FSB) with Intel processors or HyperTransport (HT) with AMD chips.
The speed of your CPU’s FSB is tied to the speed of your motherboard’s system clock or the circuit that controls the speed of all of your computer’s operations. (This value is usually listed in the BIOS.) The FSB speed is reached by multiplying the system clock speed by another value (usually 4 for current Intel processors, but it can vary depending on the CPU model). For example, a motherboard running a Core 2 Duo chip on a 1,066MHz FSB has a system clock of 266MHz (266 times 4 equals 1,066), and a Core 2 Extreme chip with a 1,333MHz FSB has a system clock speed of 333MHz (333 times 4 equals 1,333). This is important to overclocking because most chips are overclocked by increasing the system clock value to speed up the FSB.
To actually make the change, enter your motherboard’s BIOS settings screen. (Typically, you press Delete or F2 upon booting; check your motherboard manual.) Some manufacturers disable or hide overclocking settings; on some Award BIOS setups, you must press Shift+F1 to enable the advanced settings.
Look for a section labeled something like Advanced Chipset Features or Chipset Configuration. Then, find the FSB setting and increase it. (Note that while many BIOS setup utilities call the setting something like FSB Frequency, you’re actually adjusting the system clock–this mislabeling is why the number you see for the setting is typically in the range of 266MHz to 333MHz, even though your PC’s FSB is more likely in the range of 800MHz to 1,333MHz.) A 5 percent increase is a good conservative start. Reboot your system, and see how things run. If everything’s good, try adding another 5 percent at a time, until stability or heat issues arise. Then back down to the most recent stable value.
Sometimes slightly increasing the voltage of your processor or chipset in the BIOS settings can alleviate stability problems, but it also ratchets up the heat and can even damage components if you choose a value dramatically higher than the default. Start one notch up from your CPU’s default value (usually shown in the BIOS) and see if that helps; if it doesn’t, go up one notch at a time, checking for a spike in heat or instability after each increase. Many newer motherboards offer an Auto voltage setting that increases voltage automatically when overclocking; choose this if available.
It’s much easier to overclock today’s high-end processors. The Core 2 Extreme, Pentium 4 Extreme Edition, and Athlon 64 FX chip families have unlocked multipliers, allowing you to speed them up without altering the FSB or HT bus. For instance, the 2.66GHz Core 2 Extreme QX6700 has a default multiplier of 10. Changing it to 11 boosts its internal speed to 2.92GHz (266MHz times 11); 12 gives you 3.2GHz.
Step 4: Overclock your memory~
You can get an additional, smaller performance boost by overclocking your PC’s RAM. Many newer motherboards offer direct control over memory speeds. In such a case, you would use the same techniques as for overclocking the processor: Boost in small increments, then test for stability. How far you can go varies by the RAM. We easily boosted Corsair’s XMS3 DHX DDR3 1,333MHz memory, for instance, to 1,450MHz. But an older set of Corsair XMS2 DDR2 675MHz modules only reached 700MHz before stability troubles welled up.
Also, you may have to increase latency (a setting that dictates how long the system waits between memory accesses) to run the memory safely at faster speeds, which can nullify the benefit of the faster clock rate. How much you might need to tweak latency varies dramatically, depending on not just the speed of the RAM, but also its type (DDR, DDR2, DDR3). For more guidance, check the RAM manufacturer’s Web site–enthusiast brands such as Corsair and OCZ often have references showing recommended latency values at overclocked speeds, and their forums are usually full of useful examples.
Some motherboards tie memory speed directly to FSB or HT speeds, so boosting those also overclocks the memory. If that’s the case, however, you may need to adjust the memory settings in the BIOS to a slower-than-rated speed to compensate. For example, if you have 533MHz DDR memory and you boost your FSB by 20 percent, you may need to lower your memory settings to 400MHz or even 333MHz to keep the memory speed in a safe range. Otherwise, your memory could end up clocked at the equivalent of 640MHz, a speed at which it’s unlikely to run in a stable fashion.
Step 5: Troubleshooting and testing~
Overclocking too aggressively can lock up your system or cause it to crash when you first boot. If yours does, reset the computer, enter the BIOS, and try reducing speeds or increasing voltage to try and get a successful boot. If you can’t get into the BIOS at all, power off completely and restart.
Some motherboards, Asus models among them, reset to default speeds if an overclocking attempt fails. If your motherboard doesn’t, you may have to clear the CMOS memory, which contains your clock settings, to get back to square one. You generally accomplish this by moving a jumper on your motherboard to another set of pins, then moving it back. Check your motherboard manual for the procedure and the location of the jumper.
The first major test of a successful overclock is whether your system successfully loads Windows. If it does, your next step is to give your PC a workout using a series of software tools to test its stability. If it passes muster, pat yourself on the back–and enjoy your free upgrade.
…that’s it guys, hope this can help you in any ways! happy tweaking your PC… c”,)
