Overclocking Intel Core 2 Duo E4600 2,4Ghz

August 24, 2012 at 01:41:59
Specs: Windows 7
Hi Everybody,

I'm interested to see if I can improve performance of my current PC as I have no money at the moment to invest into buying new parts.

I have the abovementioned CPU, on a P5K/EPU motherboard, 3GB of RAM and a Radeon 3600 HD 3600 series graphics card.

Please tell me if I need to provide any more data or anything...

Thank you so much,

Your manual:
You did not mention what your memory speed is and this is important. I will outline a few options related to this below.
Fix your PCIe at 100MHz
Disable C1E
Disable Spread Spectrum

With DDR2 800MHz memory:
Set the memory at DDR2 800MHz (freq. 400MHz)
Set CPU Freq. at 400MHz (FSB1600)
Begin setting your CPU multiplier at 7 for a final CPU speed of 2.8GHz
After you reach stability you can begin trying a higher multiplier. Your final speed is calculated by multiplying the CPU Freq X Multiplier (8 X 400= 3200MHz or 3.2GHz). You will probably end up with a multiplier between 8 or possible 9 and most motherboards will allow .5 increments on the multiplier.
7 x 400 = 2.8GHz
7.5 x 400 = 3.0 GHz
8 x 400 = 3.2 GHz
8.5 x 400 = 3.4 GHz
9 x 400 = 3.6 GHz
If your memory is DDR2 800 then it is also running at a freq. or 400 which gives you a CPU/RAM Ratio of 1:1 (optimal) and an FSB1600 which is also best. If you raise the multiplier and it becomes unstable, you will need to raise the VCore voltage a small step or two to achieve stability. Raise it only enough for stability since higher voltage will generate more heat, and never more than your CPU can safely handle (max 1.5Volts).

If your memory is DDR2 667MHz then all of the above applies except that you will use a CPU Freq. of 333 and begin with a multiplier of 8. This will give you an FSB of 1333MHz and keep your Ratio at 1:1 (optimal)
8 x 333 = 2.7 GHz
9 x 333 = 3.0 GHz
10 x 333 = 3.3 GHz
10.5 x 33 = 3.5 GHz
Install CPUz to verify your overclock and Speedfan or HWMonitor to check your internal temperatures. Use Prime 85 for testing stability.

If you cannot achieve stability at a particular setting or you cannot control the temperatures without spending for a premium heat sink, just back down on the OC a notch or two for everyday use.

You have to be a little bit crazy to keep you from going insane.

Dear Fingers,

is this the part of BIOS where i change the information? :


if so, what do I enter and where? I've tried following your advice but however i got the message that overclocking failed so I guess I will need a bit more idiot-friendly instructions...

Thank you very much,

If better gaming performance is what you're after, you'll need a better video card. The HD 3650 isn't much good for gaming.

Your motherboard officially suports up to 1600MHz FSB & your CPU runs at 800MHz FSB. The key to overclocking your system is to run the fastest FSB available while maintaining a FSB:DRAM frequency ratio of either 1:1 or 1:2. You didn't state what RAM you have but I'll assume it's DDR2-800, that means you should be running 1:1 ratio. If you're using Win7 64-bit, it would help to add more RAM, if you have Win7 32-bit, you're good with 3GB.

Here's your overclock settings:

AI Overclocking = Manual
CPU Ratio Control = Manual
Ratio CMOS Setting = 7
FSB Strap to North Bridge = Auto

FSB Frequency = 400MHz
PCIE Frequency = 100MHz
DRAM Frequency = DDR2-800

Transaction Booster = Enabled
Booster Level = 0

CPU Spread Spectrum = disabled
PCIE Spread Spectrum = disabled

The above settings (if they work) will run the CPU at 2.8GHz @ 1600MHz FSB with a ratio of 1:1. If it boots & runs stably & you want to try for more, simply raise the ratio from 7 to 8. That will run the CPU at 3.2GHz, however, a CPU voltage increase may be necessary.

If the system won't boot with these settings, unplug the power cord, use the Clear CMOS jumper to reset the BIOS (move jumper to the "clear" position, wait a few seconds, then move it back) then start over.

Hello, :)

I have an option of ddr2-801mhz, is that it?
