Question Overclock Intel Core 2 duo E6750 on Stock cooler for E6600

[LuKaWin10]

Hello, I want to overclock my Intel Core 2 duo E6750 to 3 GHz with my E6600 stock cooler. My GPU is GT 730, mobo is P35-DS3 rev 2.1, RAM is DDR2 Kingston 400 MHz and PQI CORP. 300 MHz DDR2 4 GB TOTAL. I want to overclock it, my bios is F14, if you need more, tell me. I want to do this for fun and answer is this possible!

You won't get much with the stock cooler. Maybe 5% or so overclock which will be lost in the noise as it were.

So I won't be able to have 3 GHz?

Correct.

Correct.

Maybe less?

As said. MAYBE 5% higher than stock but no more.

I see a problem here. P35 is not able to run the memory slower than the FSB so at stock speed with 1333FSB (it's quad-pumped so 4 x 333) you are already running the DDR2 at least at 333MHz. If that "300MHz" PQI is only DDR2-667 then you'd probably have to either remove it or considerably raise the voltage or lower timings to get it to run at the standard 400MHz of DDR2-800 needed to run at the usual 1600MHz FSB used by Extreme processors.

At 1600, 8 x 400 = 3.2GHz from your E6750 which should only require a minor bump in voltage. Figure on about 68w of actual CPU power consumption, up from the 50w actual of stock (yes, these used much less than their rated 65w TDP, a concept foreign to the Intel of today), which should be pretty warm on the stock cooler but acceptable. It's a pretty unimpressive 500MHz overclock because the stock FSB is too high (better to start with a 800 or 1066 FSB chip if you wish to overclock since those will have higher multipliers) but this is exactly what allows for overclocking on a stock cooler. After all the cooler was designed to handle 65w TDP.

If your GT730 is a Kepler instead of Fermi, then it should overclock like crazy, like +350MHz. If it's Fermi then you would quickly run into the 75w power limit since even at the stock 700MHz it's already at double the wattage of the Kepler at 49w.
