This is my guide/or kinda like about overclocking,, im not complete sure about somethings so please feel free to correct me if im wrong. any help would be great. And yes i know its short, kinda summarizing/telling about ocing . .
Overclocking is turning your computer components up faster than they were supposed to run out of the box, so you get more of what you paid for, and a faster performance in your computer. There are many ways to go about overclocking that includes Third-Party-Programs or the BIOS (basic input/output system). There are also many different things that can be overclocked in a computer but mainly it is done CPU/Memory related. In order to overclock changing certain settings in the BIOS might affect the system quite dramatically in terms of performance. That’s one of the reasons that most people go on to experiment with this idea. Overclocking also has an effect on companies since it takes advantage of how CPU makers design and manufacture their chips where some problems surge.
To overclock the CPU you will need to overclock the ram also to gain the best system performance. To do this it is appropriate to change certain settings in the BIOS: The Front Side Bus (FSB), the CPU multiplier, and different voltages. The FSB is the speed that the memory talks to the Northbridge (chip or chips that connect a CPU to memory, the PCI bus, Level 2 cache and AGP activities), which then talks to the CPU. The CPU multiplier is a certain number that multiplies the FSB to give it the overall CPU frequency. For example: 10 (Multiplier) x 200Mhz (FSB) = 2000 MHz or 2 GHz. The motherboard, CPU, memory, and the PSU are generally the most important things in the system when overclocking.
Motherboard: Currently the nForce2 motherboards are the best because they offer a lot of features like the PCI lock that so many overclockers are enjoying at the moment, since they can reach FSB speeds of 200Mhz or higher. PCI lock basically locks the PCI bus speed at 33Mhz so that you will not have to use dividers and worry about your PCI bus speed causing problems like hard drive corruption which was a problem before.
CPU: All CPU’s overclock differently, and a system with certain characteristics (Components) may define the overclockability. A CPU’s max overclocking frequency on air is mainly determined by:
- The heat sink and fan. (Temperature)
- Voltage core and its stability.
- Memory rated speed.
- Chipset quality (Stepping: Identifies the CPU and its specifications) and chipset Vdd.
- Chipset (both Northbridge and Southbridge) cooling.
Temperature is important not just because high temperature could damage the CPU, but more importantly the lower the temperature, the more stability the CPU gains through the overclocking process.
A good PSU (Power Supply Unit) gives in stable VoltageCore to the CPU, thus getting a better overall overclock. When purchasing a PSU for a good Overclock focus on the Current Rating (That’s on the PSU line that generates Vcore) and not the total power (Watts).
Dual channel or single channel mode in an NForce2 motherboard does not change the overall performance as much. Also single channel may let the FSB go a bit higher due to memory controller stress at high FSB. On the other hand, dual channel memory controller provides some performance advantage due to the advanced dual memory bandwidth performance.
To get higher FSB, its better to make sure memory module is rated to handle the target FSB at a given Ras/Cas timing and voltage. For these RAS/CAS memory timing such as 6-2-2-2 1T or 6-3-3-2 1T. They refer to:
1. Active (to) Precharge Delay (Tras, tRAS)
2. RAS to CAS Delay (Trcd, tRCD)
3. RAS Precharge Delay (Trp, tRP, Precharge to Active)
4. CAS Latency (CAS)
5. Cmd Rate
Overclock --> Adjust the FSB, multiplier, voltages, memory timings and test for complete stability = Huge improvement in overall performance.
