Okay so i just overclocked my core i7 920 @ 2.66 Ghz to 3.045Ghz ( i know you can barely call it overclocking, but until i get a new cpu cooler its gonna stay like this)

But the only thing i did was change the AI Tuner to manual and the Base Clock (bclk) to 145... Is the right thing to do, no need for any voltage configurations just yet, at a clock this low?

And additional questions..
What exactly does Intel SpeedStep and Intel TurboMode do? what happens if i turn them off?will it effect my CPUs life spand?

most OCing guides will explain all the questions you asked. speedstep is for when your cpu is idle. it will reduce the cpu multiplier to a lower setting and you should disable. it is recomended that you disable turbo mode when OCing. turbo mode allows you to OC one core and leave the other cores at lower settings. it is a problem when it is enabled because it reduces the clock speed automaticaly when the cpu reaches full load.

The best overclocking can be achieved in the Bios. The 920 is a great overclocker and I wish I would have bought that instead of my i-7 940. Anyways the best overclocking is achieved in the Bios. In my Bios, I go into manual AI Tweaker mode and I raise the block multipier amd turn turbo off. Just paly with it. I used no voltage changes with my Cooler Master CPU Cooler and went from 2.93ghz to 3.42ghz with temps maxing at 48C. I highly recommend the V8 Cooler Master but it is huge and you need a big case. The other option is the Astek Liquid CPU Cooler. A bargain for water cooling. Turbo is like a self overclocking feature. I would turn it off if you plan on overclocking and from what I seen I noticed the highest overclocks with turbo off.

I just bought a i7 920, but I'm currently using the box cooler. Is it even worth it to try to gain a few clicks using this cooler?

by saying box cooler, I take you mean the standard intel heat sink cooler. Well thats up to you. You could go 3.0ghz or higher. But you have to monitor the temps. Download Realtemp 3.00 and make sure you do not over heat the cpu. The more heat to the cpu the less overall lifespan of the cpu. liquid or high perfomance air coolers are not that much. You decide. A high temp for the 920 would be arounf 67.5C. I myself would not go over 58C on full load.

Any more questions I would be happy to answer. Good luck

Cool...thanks for the info. Normally I buy an aftermarket cooler, but since I wasn't even planning on upgrading and just got caught up in the newer stuff while looking I ended up ordering parts and forgeting to get one.

I'll check out realtemp, but I've gotten so much performance gain in Lineage 2 (the main PC game I play) that I haven't decided if I wanted to OC.
