Going to overclock new computer using program, need help.

[Iruleyousuck]

Graphics card = Geforce GTX 260
Processor = Intel quad core Q9550 @ 2.83
Memory = 8gb 800mhz Kingston ram.
Motherboard = Asus Nvidia750i sli

My OS Is windows vista 64bit home premium.

Now, All I want to do is overclock my cpu to 3.00 and I'm going to use a program called "Clockgen" To do it. Now, My main question is how? What would i have to change my fsb to, to show i can get 3.00? and theirs other options as well like ram, which is at 400, PCIE which is 99.95 and PCI which is 33.31. Should i change anything else or just only the fsb?

Today's processors are usually "multiplier locked" and your Q9550 is no exception: its FSB multiplier is locked to 8.5. The default FSB of 333 MHz times 8.5 gives you the stock speed of 2830 MHz.

Since you can't change the multiplier, you'll raise the FSB frequency to 350 MHz for example, giving you a CPU frequency of 2.975 GHz. In most Core processors, the CPU voltage must be raised slightly to keep it stable. Look at the stock voltage and raise it in the smallest possible increments. Run a benchmark to check for stability, raise again if it crashes, repeat.

According to one source, the Q9550 ran fine at 450 MHz FSB (3.825 GHz CPU) at 1.31 volts. Your mileage may vary. NEVER EXCEED THE RATED MAX VOLTAGE of 1.3625V. You'll be sorry. Don't do it.

Aside from the CPU, you'll want to look at your memory. Since you have 800 MHz RAM, your memory:FSB ratio is probably 1.2. Different BIOSes report this in different ways. The gist is that "800" memory really runs at 400 MHz (it's DDR, or double data rate), and you need to tell the motherboard what the ratio between your memory speed and FSB speed is. 400:333 or 1.2 is typical. Sometimes the BIOS lets you choose the frequency directly, like "800."

Now, if your FSB is at 350, the ratio would be 400:350 or 1.143. This choice often isn't available, so you'd want to keep it at 1.2 and run the memory at 420 MHz. Any good quality memory is able to keep up with an overclock this small. Try raising the DRAM voltage from 1.8V to 1.9 or 2.0 volts if you run into problems.

Unless you've got a "Monday sample" CPU, it should easily overclock to 3.4 GHz (400 MHz FSB, memory:FSB at 1:1) with just a small increase in core voltage. Remember to monitor the temperatures and replace the stock cooler with something beefier if it gets too hot. 50°C (122°F) at idle is OK, 70°C (158°F) is not.

The PCIe clock should be kept at its default (100 MHz), the same goes with the PCI clock (33.33 MHz).

Oh, and before you do anything drastic... Google is your friend.

Hope this helps.

I'm not an expert on overclocking, though I have done it, but it's best to overclock from BIOS rather than using a program.

ya dont use a program use you computers bios there are tut. for OC on many fourms try the EVGA fourms they have a few good guides on OC CPUs
