Is it possible or would it be hard for a newbie like myself to overclock a i5 3.40Ghz haswell to roughly 4.5Ghz?

Current spec:
i5 3.40Ghz haswell
Gigabyte G1 sniper M5
H80i corsair water cooler
8gb DDR3 800 Mhz
2GB Nvidia geforce gtx 770
600w Psu corsair

Is it a 4670k?

It should be pretty easy.

4.5 sounds quite high?

I would run something like 3.8Ghz with 4.2Ghz boost.

Try it and benchmark the hell outa it

H80i should be enough for 4.2-4.4ghz, entirely depending on your CPU (Silicon lottery), and of course case cooling.

I have quite a similar setup but running 4.6ghz with a H100i. It all depends on volts.

Check the following guide for gigabyte OC tips

It's going to be a fun journey, let us know how you get on.

Yeah its a 4670k. This is going to be the first time i try to OC but i feel i have the right system now to do so. If anything it's going to be a great learning curve.
Thanks for that OC guide make, i've been searching around for something like this, it's a great help. I'll report back with results soon hopefully.

Idle temps 27C + Corsair Vengeance C70 Midi Tower Gaming Case hopefully this helps
Wish me luck

Sorry but thats really poor advice from an overclocking forum, if you can't add to the thread please don't bother in future...

You do have the right system.

You should be able to get 4.4-4.5, depending on your chip.

The guide Make linked is good but lengthy.. Ill take some snippets out for you..

An Easy 4.4/4.5/4.6GHz Template:
Here are the settings I used; you can use them as a template for your settings:

Profile #1 Basic Profile:
CPU VRIN Override LLC: Set to Extreme (this is to make sure VIN doesn’t droop)
CPU VRIN Override Voltage: 1.7-2.0v (reduce if temperatures too high is causing instability, increase if temperatures are fine and you are unstable)
VCore: 1.24-1.34v
Ring Voltage: 1.15 or 1.2v
CPU Multiplier: 44x-46x
BCLK: Auto
Turbo: Auto
C1E, C3, C6/C7, and EIST: All Disabled

Profile #2(trade VIN for vRing):
CPU VRIN Override LLC: Set to Extreme (this is to make sure VIN doesn’t droop)
CPU VRIN Override Voltage: 1.7-1.8v
VCore: 1.25-1.32v
Ring Voltage: 1.2-1.26v
CPU Multiplier: 44x-45x
BCLK: Auto
Turbo: Auto
C1E, C3, C6/C7, and EIST: All Disabled

Use either of these two profiles, though i think profile 2 looks better as VIN may cause higher temps.

Use the lower values first (at x44 multiplier) and if it BSOD's move the vcore up a bit..

For example, if you start at x44 with 1.25v and it crashes take it up to 1.26v and so on.
