OC I5 2500k help

post #1 of 231
Thread Starter 
Hey everyone,

I still have a I5 2500k 3.3ghz CPU and i want to OC it to atleast 4.0ghz, preferable 4.5ghz. My motherboard is a ASRock P67 Extreme4. I never OC'ed before, i guess to afraid. Since the CPU is 6 years old i am not sure if it's smart to do. But i really would like to hit the 4.0/4.5ghz numbers.

Anyone here who can advice me what to do? I would appreciate it alot! thumb.gif

4.0 GHz would only be a 300 MHz increase because you are overclocking the Turbo frequency which is 3.7 GHz maximum. So, let's shoot for 4.5 GHz.

 

In general, increase the Turbo ratio/Turbo multiplier (whatever your motherboard's BIOS calls it), and also set the voltage manually so that CPU-Z displays at least 1.35V while testing with Prime95.

Thanks for the reply.

I was reading about OC'ing the I5. And what i notice is that alot of people are disabling the turbo boost in the BIOS. What do you think about this?

I don't know. I can't do that with my BIOS or else I can't overclock. It might depend on the motherboard.

 

I have to go though. I have a long day ahead of me. I'll be back when I can though! :)

First of all what CPU cooler do you have ? 4.5 GHZ should be relatively easy to achieve, I don't think you would need more than 1.32v.

Yep, should be more than enough to achieve 4.5 GHz.

Good to hear.

Can i do the OC in the tuning software from ASrock, or do i have to do it in the BIOS?
post #10 of 231
You can do the overclocking from the overclocking software provided by ASrock but it's better to do it from the BIOS as it's more reliable. In most cases you have access to more settings in the BIOS than the software on a operating system.
