Hi everyone, i've got a Core 2 Duo E6750, a Mobo Asus Stiker 2 NSE, 4Gb Ram(1600MHz), GTx 560Ti and i can´t overclock my CPU more than 3GHz or it will start heating a lot, i've seen people overclocking to 3.4GHz, without changing the core voltage (1.35v) and I got it to 1.36v and I only can overclock it to 3GHz so it doesn't heat up a lot. Please help me.

What CPU cooler do you have? What is it doing to hinder a further OC.

stock CPU cooler, what is hindering a further OC is the Temperature of the CPU

STOP!!! Get an aftermarket cooler. DO NOT OC on a stock cooler. EVER!!!

It was on an open air test bench. DO NOT continue. Every CPU behaves differently, even 2 separate E6700 can have different temperature ceilings.

Coolermaster Hyper 212 Evo should do well and it isn't expensive.

will that work for a core 2 quad q9660 or a q9550? What do you think of corsair H50?

The Corsair H50 is horribly overpriced for the performance it gives.

Yes it will fit a 775 socket. Note at the bottom :

Settings from what? PC or overclock?

So with that Cooler Master Hyper 212 EVO, i will be able to overclock it to 3.5~3.6GHz, right?

The OC... What settings are you using to try and hit 3GHz?

The 6700 is on 65nm, which isn't famous for hitting around 3.5GHz. A few can, but most won't. 3.0-3.2GHz should be doable.

it's the 6750 not the 6700 (the best sk. 775 for overclock). i already hit 3 GHz but i want more (3.4 GHz at least ) but i can't because it's temperature stays at 90ºC at gaming, but at 3.00GHz stays at 45~50ºC

i don't remember me very well but i think that is this:
FSB: 1500
Ram(ddr3): around 1400MHz
core voltage: ~1.36v

Ok....

1500 / 4 = 375. 375 * 8 = 3000GHz. Can't figure the ram speed but sounds like you are using ~ double the FSB. Assuming you are using 1600MHz ram that shouldn't be the issue. Nice to see the voltage isn't to high.

What happens when you use 400FSB? Drop the CPU multiplier down to 6x. This should give you a 2.4GHz CPU. But it will tell us if your Nvidia chipset board can even handle 400MHz.

my CPU multiplier is already at 6.0, my Ram is 1600MHz but this motherboard only accept 1333MHz ram (or 1600MHz overclocked), and i only got it around 1400MHz (i selected an memory level up to pc3-11... dont remember very well) tommorow i will bring some screenshots because i'm not at home and don't got my pc here

? I thought you said you were running it at 3GHz? 375MHz * 8 = 3Ghz. (yes, I made error in post above...) If you are running a 375MHz FSB, you only have the CPU running at 2.25GHz?

To make OCing easy change the FSB:RAM ratio to 1:1. That way you don't have to worry about the ram.

and i am but the multiplier is only 6x(i think), but tomorrow i will bring some screnshots

Depends. It will keep it cooler. Might help, might not.

here are the screenshots (what u can't see in the first one due to the flash isnt important, it's just says cpu level up--> auto; and memory level up-> auto; ai overclock tuner--> manual)

The 212 is better. I saw the 212+ onsale on newegg for $20 after rebate. (might have been $25, don't remember.) If the Evo is too much, the 212+ is still good.

Ok, from what I can see. CPU multiplier is 8, so you are running 3GHz. (375*8) Memory is linked and at auto, so change that. Drop the CPU down to 6 or as low as it will go, link the memory at 1:1, and then bump the FSB up to 400/1600MHz. See if it boots.
