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.

 

[LuKaWin10]

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.

I think it is a Kepler (will check later) because I think Kepler ones have GDDR5 VRAM types and are different in shape and looks!

e6750 default bclk is 333, if you want overclock much have to increase pci freq. but it have a benefit is your ram multiplier is low and oc e6750 don't affect ram too much. there are lot of thing to manage, try 105, 110, 120, 150... pci freq and which your gpu can't operate normal. then overclock bclk. I'm sure it don't damage any ssd hdd when oc pci e freq but it affect gpu, usb device. if you need you can take a photo of voltage in bios setting mb intelligent tweaker then I'll say more. these guide is enough for you to do a little overclock. If want overclock cpu as much as possible never use 2gb ram stick. It usually can't pass 1000mhz and will corrupt data, only use 1gb stick. I recommend use kingston or kingmax, I can normal overclock it more than 1400+mhz without any problem so I have free 1400mhz ram. This is for expert ocer
