Increaseing The Clock Multiplier
quite healthy. If your system becomes unstable during this test, or your temperatures reach unacceptable levels, you'll need to go back and readjust your clock speed, multiplier, and voltage. What is it exactly, and what is the motherboard? Consequently, processors produced in the same batch with identical FSB ratings may end up with different speed ratings because of multipliers assigned to them.
The goal here is to get better, stable performance for your money.

Cpu Bus Frequency 8350
Some CPU engineering samples may also have the clock multiplier unlocked. Therefore, as you try to overclock BCLK, the VTT voltage(aka IMC) is what you'll need to increase. Overclockers tend to refer to the base FSB clock rather than the effective speed, because the base clock frequency is usually the value shown in the system BIOS. Like so with Terran Conflict running: __________________ Best Regards from Steve in Portsmouth, UK.
Front-Side Bus All processors have a core bus speed, which most refer to as the front-side bus. Lower the iGPU's frequency, so that, as we up BCLK, it won't ever go higher than its default. You should now have settings that just barely cause your computer to become unstable. Evolution Cp Multiplier Sorry There was an error emailing this page.
Still other motherboard BIOS menus may allow you to change FSB and multiplier settings. What Is Cpu Multiplier POST A COMMENT 0 Comments View All Comments PIPELINE STORIES + Submit News NVIDIA Releases Android 7.0 Update for SHIELD Tablet Eurocom Launches a 780 W External PSU for Laptops GlobalFoundries Note that Intel's latest CPUs also have a feature called Turbo Boost that allows the CPU to run at clock speeds higher than the default speed under certain conditions. http://www.tomshardware.com/answers/id-1793612/difference-changing-bus-speed-multiplier-phenom-965.html What i wonder is if its the base frequence (200MHz) of the CPU that wears out the components or the multiplied frequence.
All rights reserved. Cpu Multiplier Calculator Regardless of the method you use to overclock your computer, ensure that you make changes in the smallest increments possible and use benchmarking or burn-in software to verify stability before increasing Would any part of the CPU take any damage if i increased the FSB and lowered the CPUs multiplier to lets say: FSB 266MHz x4 = 1066MHz RAM 533MHz x2 = In PCs, the CPU's external address and data buses connect the CPU to the rest of the system via the "northbridge".
What Is Cpu Multiplier
For Core 2 processors, the first clock of note belongs to the front-side bus. Visit Website Clock multipliers on many modern processors are fixed; it is usually not possible to change them. Cpu Bus Frequency 8350 FSB raising requires much more stress testing time to reach stability, and even when you think you have it stable something as simple as opening your favorite game can bring your Clock Multiplier Circuit Subscribe ▲ Learn more about PCWorld's Digital Editions 🔎 Home News Reviews How-To Video Business Laptops Tablets Phones Hardware Security Software Gadgets Subscribe Resources PCs Phones Printers Ultrabooks
The FSB is notable because processor clock speeds are determined by the product of the base FSB clock and the CPU multiplier. Laptops are not very good candidates for overclocking, as their cooling capabilities are limited. This may seem like a long time, but your goal is to ensure rock-solid stability at long periods. What you can do does depend on the motherboard and the maximum FSB the processor is stable at, and the Asus P5KPL has many versions with bioses of different ability. What Is Cpu Clock Ratio
Of course, the CPU isn't the only system element that bases its clock speed on the front-side bus. No two systems will overclock the same, even if they have the exact same hardware. However, if you want to overclock the processor as much as possible, you'll probably need to increase both the FSB and multiplier. There are also slight differences when it comes to overclocking AMD versus Intel, but the general process is the same.
Part 3 Raising the Multiplier 1 Lower the base clock. Clock Multiplication Definition That should give us a memory clock of 780MHza little slower than stock for these DIMMs, so we're sure overclocked RAM won't be a source of instability. Gaming systems made by these companies, though, usually do allow you to adjust some speed and voltage settings in the BIOS.

In this guide, we'll cover exactly how to take the RAM, CPU, iGPU, and QPI frequencies out of the equation, and then we'll go over actually finding the upper limit for Overclocking with voltage increases will shorten the life of your hardware. The internal frequency of microprocessors is usually based on front side bus (FSB) frequency. What Is Base Clock Bumping it up 10% would change the base clock to 110 MHz, and the clock speed to 1.76 GHz. 5 Run a stress test.
Last edited by system7; 01-30-2011 at 06:51 AM. For example, the Core 2 Duo E6750 is advertised as having a 1333MHz front-side bus. Increasing FSB and memory speed while keeping CPU frequency stable (by lowering the multiplier) should give a tiny performance boost without risking the CPU. Finding the perfect balance is the goal. 2 Raise the multiplier.
Increasing the multiplier raises the speed of the processor only and does not increase the FSB data bandwidth speed between the CPU and memory modules. Gigabyte labels the base FSB clock as the CPU Host Frequency. The time now is 08:37 PM. A 400MHz memory clock corresponds to an effective memory data rate of 800MHz. (This 2:1 ratio between the base memory clock and the data rate holds true for all DDR memory
Next, change BCLK from 133 to 150. Co-authors: 72 Updated: Views:2,036,749 Quick Tips Related ArticlesHow to Construct a Simple 5V DC Power SupplyHow to Install a MotherboardHow to Upgrade Your Laptop's RAM MemoryHow to Underclock a PC Home That's a story. Depends on the processor.
