# Overclocking the i7

#### jdelsignore911

If I try overclocking the core i7 920 will I have to adjust everything in the guide on tomshardware like the memory and fsb speeds. Or can I just increase the speed say to 3.0ghz from 2.66??
Thanks guys for helping (I have never overclocked anything...)

Solution
Dude, seriusl you need to read up more.

The base clock is what sets the speed.

The multi is what the base clock is multiplied by to get the speed.

the i7 920 has a multiplier of 20.

Example:

(Base clock) * (multiplier)= The final speed.

So the stock settings would be:
(Base clock) * (multiplier)= 2.66

and as i have already said. the multipler for the i7 920 is 20 this gives us the following...

(Base clock) * (20)= 2.66

Simple alegebra dictates that the base clock must be 133 in this situation.

_____________________________

So then obviously 150 base clock would give us 3.0 ghz because of the following.....

(Base clock) * (multiplier)= The final speed.

(Base clock) * (multiplier)= 3.0GHz

(Base clock) * (20)= 3.0GHz

(150) *...

You will need to adjust the base clock (because that is what gives you higher speeds)

But all the other stuff is recommended.

You should be able to get it to 3.0Ghz without even changing the voltage. Just raise the base clock from 133 mhz to 150mhz

what is the base block and how do you know 150 mhz is 3.0 ghz??? Im new at this stuff sorry.

Get it?

Yes Thank you. What speed do you think I could get with the stock cooler??

3.3Ghz sounds pretty obtainable...

But it really depends on the chip.

You should seriously consider getting a new aftermarket heatsink if you plan to OC.

What heatsink would you recommend for the i7 920?

The core contact freezer its \$24 on ebay right now but the \$15 mail in rebate is up tomarrow, so hurry!

#### jdelsignore911

Is that on Newegg? I like them but will check it out on ebay.

#### jdelsignore911

##### Distinguished
Should have checked... It is on there sorry...

#### overshocked

^ its cool dude...

I would get that one, it is the best price/performance value

I dont know if it will fit in the Antec 900 though. Will it??

It should... measure it!
