Hi can any one tell me how to overclock the following CPU. Intel Core i5 4690 with Asus Z97-A S1150 I'm new to building PC and was wondering it there is any step by step videos or forums.

What would be a safe limited to overclock to? would there be a noticeable difference in performance and gaming?

Will it make a difference to the graphics?

Is there a way of making the system boot up faster? Going to be running windows 7

I have a Coolmaster Evo 212 as a CPU cooler

Thanks :)

Ok then,



With a cooler like that, 4.5Ghz will be a good OC. That'd be a good performance increase, as in gaming, games mostly heavily rely on single thread performance.

Nope, as the CPU is powerful enough to not bottleneck any dedicated GPU, so OCing won't really make any difference to graphics, using Integrated graphics is a different story.

Now to the main thing:
You'll have to increase the multiplier, its like on 35 which means...

Now to the main thing:
You'll have to increase the multiplier, its like on 35 which means 35*100MHz=3.5Ghz, increasing it to 42 will give 4.2Ghz and so-on.

Increase by 1 or 2 first, then boot and check stability using Prime95 and temps using Core Temp or a suitable program. It should contain the 100% load for whatever amount of time you run the test for, 1 hr is the least I'd recommend. The temps shouldn't exceed 72C.

Repeat the steps to increase the multiplier by 1 or 2 then check for stability, till you BSOD while Prime testing, literally! This'd mean you should either go down with the multiplier to get stable OC or increase VCore to be stable on the present config.

Increasing VCore or Voltage manually to something like 1.2V +/-0.5V will most likely solve it.

Try going to 4.5Ghz with this method, you can go further until you can't manage without a VCore of more than 1.35V which I wouldn't recommend, that'd be your final OC, most likely. 4.6Ghz is do-able if you're good enough with this.

NOTE: Test for stability on each step taken, weather its multiplier or VCore.

One minor addition to the above instructions.

If you want to stress test with Prime95 after changing settings, be sure to use version 26.6! The latest version (28.8?) heavily loads the FPU of the CPU by running a high AVX instruction set. This will result in abnormally high CPU temps, which is of no use.
