i7 4770k Overclock? Please Help!

[bdank2]

Hi, I want to overclock my CPU to 4.2Ghz, I watched linus's guide but it didn't really help me. I don't know what voltage to set, linus set his to 1.2 but that was for 4.6Ghz, I'm just wondering whether that would be too high for only 4.2? Can anyone help me, a guide which is simple would be great!]

 

My Specs are down below...

 

These are my pc specs:

Motherboard: Gigabyte Z87x-ud3h

CPU: i7 4770k

CPU Cooler: Corsair H100I liquid cooler

GPU: EVGA gtx 780 acx FTW

Power Supply: Corsair CS750M Gold

RAM: 16gb Corsair Vengeance Pro 1866mhz

it depends on the chip, some overclock great, others cant for shit.

1.2v is good for 4.2, linus got lucky with his clock and voltage normally for a 4770k at 4.6ghz you would need 1.4ish

To be really concise, here's how you do:

 

- Set the voltage to manual and let the default value

- Increase CPU ratio by 1

- Test (Prime95,...) for ~20mn

 

Crash? Increase voltage by a 5mV -> Test again

Stable? Increase CPU ratio by 1

Rince and repeat.

 

Be careful about your temperatures though, the 4770K is well-known for hitting high temps really fast. Try to keep it under 80°C. If you can't, time to reduce overclock or buy a new cooler.

 

EDIT: To give you an idea, my 4790K hits 4.6GHz at 1.33V and peaks around 80°C, watercooled. You should be able to go for 4.2GHz for anything between 1.15V to 1.25V depending on your chip.

Thanks so much I'll try 1.2, is there any other settings I need to change in the bios before I overclock, I got a little lost in his guide haha..

Try 1.125 volts for 4.2 GHz. It should be stable for a 4770k. If its not, increase it to 1.150.

Great news guys, I tried 4.2ghz at 1.5V and is been testing on PRIME95 for about 10 minutes and the top temp 50 degrees. Thanks so much

1.5v !?!?

Turn that DOWN. 1.3-1.35v safety MAX. You're going to fry your chip. You can't just use the core voltage to OC. You need to manually tune all of the voltage settings (cache, VCCIN, RAM, and offsets if you're fine tuning).

I think he mean't 1.15V

I think he mean't 1.15V

I hope so

[bdank2]

Yeah SO SORRY I meant 1.15V hahaha
