Q6700 Overclock stuck at 3.0Ghz, high temps and instability... HELP!

post #1 of 2
Thread Starter 
Here are my system specs:
Intel Core2 Quad Q6700
EVGA nForce 680i Mobo 122-CK-NF68
4 GB Ram Mushkin HP2-6400
Scythe Ninja Plus Heatsink and Fan
Gigabyte 3DAurora Case - Has 2 Fans on back, 1 on front
EVGA GTX 570 SC

I've read on forums of Q6700 going up to 3.4 Ghz no problem. But I'm having problems getting anywhere near that. This is my first overclock, can someone give me some help?

The highest SOMEWHAT stable build I was able to get is:
9 X 333.5 Mhz = 3001 Mhz @ 1.265 Core Voltage. (Using a 10X multiplier to get up to that core speed was unstable)
Idle temps: 41 - 48 Degrees
Load temps: 67 - 76 Degrees (!!!!) w/ TjMax set @ 90 Degrees

Why are my load temps so high, even though my Core Voltage is no where near the max (1.5V)? I've tried going higher FSB but it requires even more voltage and I'm already high in temps.

Your temperatures are so high because you're using a not so great cooler on a VERY HOT running CPU.

You're hitting a wall with your overclock because you have a 680i motherboard. 680i boards absolutely sucked with quad core chips.

You can try increasing your voltage, but you'll need better cooling for that. I've got my Q6600 at 3.6GHz, 1.58v on my BloodIron (P35). Works like a dream, load temps of 72*C.
