I've had a 920 D0 at 4GHz 24/7 for a year and a half. No issues there, it's all just free performance should you choose to use it![]()
Coming up to 17 months i7920 at 4.2GHz, no problems at all, as peeps have suggested just overclock it to a 950 3.2GHz, you should not have any problems at that speed in the long run..

Just be mindful of your temps and cooling. If you're just on stock cooling I'd highly recommend you get a good cooler before attempting this.
