How to overclock E6300 to E6600?

Question

Motherboard: GA-P965-DS3
RAM: DDR2-667
FSB:RAM 1:1

To increase the processor speed from 1860 to 2400 MHz, there will be a need to increase the FSB from 266 to 343 MHz.
The problem is I do not know how much to increase the voltage to the processor by? Is there a need to cause the overclocking is not really by a lot.
I will need to overclock the RAM too from 200 MHz to 343 MHz. How do I go about doing this? How much voltage should I add?
DDR2-667 is it enough to pull this off or must I get at least DDR2-800?

Thanks.

This article shows how they overclocked an E6800. Perhaps you can pick up a few pointers from the methods they used.

Ok, first of all overclocking is a very dangerous thing to do and will severely damage your equipment if not done correctly.


BEFORE YOU BEGIN, MAKE SURE YOU HAVE AN UTILITY TO MONITOR YOUR PROCESSOR TEMPERATURE WITH, IF YOU DO NOT HAVE A MONITORING DEVICE, I STRONGLY ADVISE YOU TO NOT OVERCLOCK.

With that said, lets begin.

I reccomend starting off by dividing the RAM speed as much as possible (like a 1/2 divide, example 300 FSB @ 1/2 divide would be 150MHZ memory speed). By dramatically reducing the memory speed, you will be able to eliminate instablility due to memory failures.

Once you've done that, you should start bumping up the the FSB about 5-10 MHZ at a time. Each time you boot into Windows with a new speed, test it with OCCT. Continue increasing the speed of the FSB until OCCT fails. If OCCT fails, power down and increase the voltage little by little until your computer passes OCCT again. Continue this process until you have reached your desired speed. OCCT is used to test general stability, but does not actually mean your computer is stable. Test the processor with PRIME95 for a few hours (I usually try to pass 8 hrs on torture mode). If your processor passes Prime95 for 8+hrs, your processor is quite stable. (You can also do SuperPI 32million to test stability too.)

Now to overclock the memory.
Leave the processor overclocked and begin to bring up the memory divider. It will might not reach 1/1, at this point you can either increase the memory voltage (I have not worked with DDR-2 so I cannot give you any advice on this), or slow down the timings (example, CAS, RAS, RP, etc.) If the memory gets pushed too hard, your computer may not boot (example, press power button, screen is still black, but getting a signal from video). In this case you will have to clear the BIOS in order to reset the overclocking allowing your comptuer to boot again.

Check out this site: http://www.dfi-street.com/forum/showthread.php?t=28049 for a comprehensive overclocking guide that will cover most of what I have just said. (Most of the stuff applies to both AMD and Intel processors).

Final Note: Your overclock may be limited by many factors including your POWER SUPPLY and COOLING. The wattage on the PSU does not always mean that it is powerful, when purchasing a power supply, make sure to check the amperage (A) on the +12V rail, 40+ total amps is very good. Some stock PSU's have as little as 17A (My friend had one of them...) Stock cooling provides minimum cooling, just enough for stock speed, you may be able to OC to 2.4 on stock, but your processor will most likely be very hot.

Feel free to contact me if the guide does not cover all of your questions.
