Going Quad

Thanks Blitzen thats good to know. I may give it a go at the weekend.

Yes - out of spec voltage or out of spec temps will reduce lifespan. You don't need to go out of spec on either to get a good overclock though.

My Q6600 can go to 3.4ghz without any voltage adjustments so, in theory, it shouldn't affect the lifespan of the core.
3.6ghz is possible in some cases without voltage adjustements aswell. (only a lucky few though as most do require a little juice increase)

I wouldn't be so sure about those clocks now. Alot of the latest Q6600 batches are coming with VIDs of 1.3250v, which is much higher than the older batches. This generally translates into a lower overclock. My Q6600 is stuck at 3.1Ghz and a few other people who bought recently on here and over at xs are hitting the same wall.

Still, 3.1Ghz is fast but I invested in a QX6700 to get higher hopefully - will be a shame to lap a £590 chip and void the warranty, but meh...

My advice if you want a high clocking Q6600 is to head to eBay and pick one up a used one for £130.
